This is for all of those that dont think slapper bars work on Mopars.I ran the Dart today and had my best 60' of 1.60 flat with the slapper bars i got off craiglist for $30.00.Notice in the second vid how the whole car lifts front and back ,and the rearend slams down hard.The track sucked for traction IMO,but i still was yanking both front wheels about 3 inches in the air all day long (first time to get the wheels up on it ever).Not bad for 4.10 gears and a high first geared Powerglide ,behind a 10 to 1 smallblock. .Time for sum more motor and gears.

Cool. I think the whole 'slapper bars don't work on Mopars" myth was started by DC as a ploy to sell more pinion snubbers.

Slapper bars, will work fine until your torque output combined with final gear multiplication overpowers the short front MP spring segments leverage ability vs the cars transfer weight on said axel.

The result when that happens, is extreme rear body lift bouncing off its axel arc limits thereby creating a porpoising effect.

Your car with the powerglide vs it weight will be more forgiving with slapper bars vs a 727.

Your cars running great, but if you get much faster with more power/torque. You will see first hand the limits of the slapper bars on the short front spring segment Mopars. So far youve done great IMO With some good adjustable rear shocks you may be able to take those slapper bars to even faster ETS. mike

I'm Happy that the bars worked for you. Sometimes it is amazing what $30.00 can do for you!! But to be honest with you...if the slapper bars work, that means either your leaf springs are too soft or you shocks are worn out. The slapper bars just keep the front of the leaf springs from winding up. A good set of springs that are correct for the car should do the same thing......but $30.00 is a lot cheaper that $330.00 for a good set of springs.

With SS springs you dont want or need slapper bars. The design concept of the SS springs is to make them extra stiff enough in the first place. With even more biased design stiffness on the passenger side, where its needed to prevent unwanted axel rotation.

If your hanging slapper bars on SS springs all your doing is adding extra ballast weight.IMO mike

Its odd Sam .My 60's went down about .004,but my ET was about the same as it was before.My previous best was a 7.27 in the 1/8 before with a 1.63 60 ,but i could only muster a 7.29 with a 1.60 60 .I was having sum problems with the car wandering on the big end in both lanes all ten passes.They ground the track recently and theres not much traction on the big end .The car is also about 60 lbs heavier than the last time i ran it.I got sum of it back gutting it more,but between the rollbars ,rear fire wall ,and the heavy slapper bars its heavier .The car is deadly consistant though in the 60' .I was getting either a 1.61 or a 1.60 60 foot every pass all ten passes .Now i just need to motor her up with more cam and stiffer valve springs .Only problem i had was the tach quit working on the first pass.I kept trying to fix a wiring problem between rounds ,but it was the tach.I ended up buying one at the track from a vendor (and got raped) ,but i had to have it.It sucks not knowing what rpm your doing a burnout at ,launching at ,or trying to shift at .Car ran good though ...

very cool car but it really doesn't prove anything. we ran the same 60' in my sons chally with a pretty much stock 340. with bone stock 6cyl front and rear suspension. if you really want to prove it helps make a pass record the times and come back and take the slappers off. I'll bet you will see no difference

No extensions on the jets.In that on vid where it shows my car from the rear ,im not the car sounding like its getting in and out of the throttle its the guy in the other lane.He was having bad traction issues all day with that thing .He had a blown big block in it and it drowned mine right out in the vid ...

Proly had a 3 spd trans behind the 340 with lower gears as well .I proved that slapper bars can stop spring wrap ,and control wheel hop ,create lift (hence the wheelies all day),and lower your 60 foot ,plus make your car more consistant on a Mopar for $30.00(i'd have to say that either a 1.60 or a 1.61 on ten passes in a row is fairly consistant).What more is there to prove ???

anything that stops worn out springs from wrapping may help. but the true test would be doing like I said. try them with and then with out back to back.

3 inches or 3 foot whats the difference.Air is air .Trust me it pulled both of them off the ground evenly a few inches.Unless about 40 people were pulling my cord .I felt the front tires hit every time as well .No it didnt get on the bumper ,but thats not the slapper bars fault.I dont have the gears, stall, or motor for that kinda show ...

Slapper bars are a cure (stiffens the front half of the leaf springs) for a problem (weak front spring halfs winding up), just like pinion snubbers BTW, is your car hesitating at all on the initial hit? If so fix that and see how much your sixty ft. times increase9lower)

Re: For all of you that think slapper bars dont work ... - 02/28/10 03:13 PM

While I think any forward progress is good, I agree with most of the posters about it helping but only at the level you're at now. Something else too... How sure are you that the springs are good? That might explain the "wandering" you feel in your seat. Not traction, just not good suspension control at higher speeds. That is a sing of bad springs too. The deal with the lack of traction bars on mopars comes from having a snubber that's properly set up and traction bars, which can interfere with each other. I also agree that a Glide with 4.10s will hit much softer than a 727 with the deeper first. I think you would go faster with 3 gears providing you can actually hook it with the extra torque that gives.

Heres a vid of my car the last time i ran before the slapper bars.Notice how it comes off the line and jerks to the right .No lift on the rear of the body and this was with the springs clamped in three spots on the front segments.It still wrapped the springs bad ,so bad that the shocks had dents in them from rolling into the rearend housing.My 60 foots ranged anywhere from 1.65 most of the time to 1.71.Best 60 at that point was 1.638 once on a well prepped track.Now my 60's are 1.60 or 1.61 everytime and it lifts the front and back of of the car evenly with no spring wrap ,and pops the wheels off the pavement.My point is that noone said before that slapper bars work in sum applications on Mopars.I always heard a blanket statement that "They just dont work on Mopars".All im trying to say is that they do work if setup right ...

Nice results! I had a set of HD Lakewoods that had been on my shelf for 20 years after pulling them off a 69 Super Bee project car. I figured what the heck and put them on my Plymouth and they really work great.

You guys that say they just stiffen the front segment are wrong; they act as a lever to apply lift at the front spring eye. Most of the info in those old Mopar manuals shouldn't be taken for gospel. The traction bars can be very effective with some combinations, but of course there are other and sometimes better ways to get the job done.

in that video it looked like the car went where it was aimed and then you corrected it. it didn't jerk right it just drove where it was headed. there are way to many varibles that can effect traction. so only a back to back same day same conditions could prove it helps one way or the other. you will hear some people say snubbers don't work also, and yes they are both band aids to weak or bad springs. but they can help prevent spring wrap if adjusted right just like your slappers. but add another 100hp then come back and tell us if they will work.

Re: For all of you that think slapper bars dont work ... - 02/28/10 04:49 PM

Shocker, they are working well if you have no spin off the line. Might require some better shocks down the road to expand the range of hp and torque they can control.
I wouldn't worry too much about those that want to pick apart what you are doing. Just refine your data recording for your own purpose, keep an eye on what out there works, and how. With enough shock control and travel, combined with front suspension tuning, you might not need to upgrade till you need a full cage!

Years a go I used them on my duster mainly to prevent the windup which worked great for that but I took it a step further and shimed the right side so it would hit first kinda like the same theory used with SS springs.

Re: For all of you that think slapper bars dont work ... - 02/28/10 06:18 PM

Slapper bars are just like any suspension mod. They either work for you or they don't, for what ever reason. Find the reason, make the adjustment , or modification, and it can work.

The only drawback from using a slapper that I saw, happened to my buddy. He ran an AMC rear end from a AMX in his 343 powered Spirit.

First time out at the track he broke the spring perches off. Had that repaired.

The next time out, he spun the center of the axle housing, causing the tubes to break the factory welds. The driveshaft took a beating and he also broke the rear tailshaft housing of the 4 gear trans.

Well, he had all that repaired and switched to an automatic AMC 727.

He has no issues now. The car hooks hard and fans the rear segment of the springs like a peacock. It was something to see. I wish I had a camera with me that day.

The only concern about slappers has always been breakage somewhere in the suspension, etc.

He is planning on upgrading to Cal Tracs eventually.

Your right the car picked up and i learned my lesson about how slapper bars wont work on a Mopar .Im not saying that slapper bars are the only option or the best ,but they are very cost affective .Please keep in mind that we are just a bunch good old boys having fun at nostalgia drags ,not a bunch gold chainers that just sit back and throw money at are cars .If a cheap solution is solving the spring rap problem on my car (which is the only car im concerned with at this point ),then i will take it.If you want to send me a set of Caltracs and mono leafs for free ,i will be glad to give them a try for you ,and let you know what happens .Till then i will use whats working now .BTW i have never heard the statement that "slapper bars will work fine on a Mopar up to a certain hp ",i have always heard the blanket statement "they wont work on a Mopar ".I was just trying to show that they can work is all ,but anything can be picked to death ,and what if'd to death as well ...

Thanks for the support man ... Im gunna get a set of adjustable shocks for it next .I only race the car a half a dozen times a year proly ,but i always want to go a little faster each time out (who doesnt).She will come around a little at time ,solving one problem at a time...

Re: For all of you that think slapper bars dont work ... - 02/28/10 08:13 PM

I am not saying they will not work but side by side runs would give better info. the point I was trying to make is that at your power level it doesn't take much to get a handle on traction. imo a good set of shocks would probably help more than the slappers. I ran snubbers for years and adjsuted properly I know they can work at a mild power level. I am a fan of your car and it's good to see you have it performing better know matter what you had to do.

I can top that! I bought a pair for $20 at Carlisle last year for my 92 D150. I race it occasionally and didn`t want to spend the $ for Cal-Tracs, I couldn`t leave over 1,600 with out wheel hop and tire spin. I put the bars on , clamped every leaf in front of the rear housing and replaced the air shocks with a set of B body Ranchos I had on my Dart when I had S/S springs and now I can leave at 2,000 with out spinning. It only runs low-mid 15s but its not spinning anymore.

Did you make all those changes at one time, if so
I'll bet the biggest factor was the adjustable shocks
that didnt let them hit the end to cause the lift
on the axle.
Anything that helps the car is worth the price, but
every thing DOESNT work on ALL cars

Re: For all of you that think slapper bars dont work ... - 03/01/10 01:06 AM

I know that! I`ve been flogging my Dart for 28 years and have made a lot of changes that didn`t help/work. I did the mods in stages, I think the shocks helped as I can adjust them and they have to be better than stiff air shocks. I was pretty happy with the minimal investment in the setup as its not my primary race vehicle. If I ever get a few extra bucks I`d like to try a drag radial or some type of dot legal race tire I can drive to the track with. As I said its not real fast but everytime I race it I go rounds.

i had slappers back in the day- the good ones that replace the spring plate, and they worked fantastical! the only reason i got rid of 'em was they hung down just a little too low, and the policia took exception. they really do work. in your application and mine, anyway.

Re: For all of you that think slapper bars dont work ... - 03/01/10 05:38 PM

I ran slapper bars on the Spirit with great success. A friend of mine has a Spirit also (a little quicker and lighter than mine) that had slapper bars on it too. He bought CalTracs and installed them on his and didn't pick up anything at all.... we had the slappers dialed in that good. Mine was preloaded a bit on the right side and the car launched straight and level and would get a couple of inches of air every time and it seemed to launch good no matter how bad the track was.

Both of our cars had a little problem when shifting into second on marginal tracks though. You could feel the rear end lift, but not bite.

My 60's were right at 1.58/1.59 when it was a good day and the car was running 7.25 or so.... that was in real good air at Ennis.

Here is a video of the car launching against another car I built. the wagon is using Cal Tracs.

It's nice to try and improve the performance of your car with simple fixes just to see if it works or not.I know todays traction aids are way better then what we had years ago and in fact i'm still running a snubber on my and i have no reason to spend the big $ for Cal Tracs when the car works just fine.
Here's a vid of my car with a fresh 408 in the beginning of last year.It was opening day and the traction was almost non existant.

1.60 short times with a 8.0" tires and spinning?
Like someone stated, they were a crutch to help and problem else where. Springs, Shocks or whatever. I run a 9.0" tire with springs. I have no snubber or bars. I foot brake the car with a 727 and 60's are always one the money at any track. The best 60 foot is a 1.42
Now I would work on getting the car to hook with out the slapper bars. After the car is working "right" with out the bars, and see what happens then.

1.60 short times with a 8.0" tires and spinning?
Like someone stated, they were a crutch to help and problem else where. Springs, Shocks or whatever. I run a 9.0" tire with springs. I have no snubber or bars. I foot brake the car with a 727 and 60's are always one the money at any track. The best 60 foot is a 1.42
Now I would work on getting the car to hook with out the slapper bars. After the car is working "right" with out the bars, and see what happens then.

Not sure if it was spinning before or not.I do know that it was rapping the springs badly .It dented both shocks where they hit the rearend housing .Big diff between a 727 first gear and a PG first gear .Gears multiply torque big time ,and also create better 60's in the process if it hooks up.Try to get a 1.42 60' with your motor with a PG and 4.10's on 8.5 slicks with 3500 launches (Traction bars or not ).Saying one motor/car gets these 60' times and this one doesnt without listing other details is kinda like people saying they are better at setting the car up because they beat a 440 big block with their 360 ,but they left out small details like :The 440 had 9 to 1 compression and stock cam in a 4,400 pound New Yorker and their 360 had 14 to 1 compression and a .600 lift solid roller cam and was in an altered.Small little details like that can have small little bearings on things .See what im getting at ?

Another choice that can work very well for some combos is the old South Side Machine lift bars,Jegs has taken them over and sells them under the Jegs name. I purchsed a new set off Ebag a year ago for $22.00. Shocks are a KEY to making any suspension work well.

The ones i got for cheap are real old .I have been told by a few that they are old Foxcraft Comp lift bars.I was told by the guy that i got them from , that they were purchased in 1970 for a GM by his father.The hole spread for the U bolts on the spring plates were the same as my Darts and had a plce for the shock bolt on both sides front and back.The only problem i had was that the plates hit the backing plates on the brakes slightly .I trimmed off about a 1/4 inch and the went on no problem .The snubbers i used are just Mopar front A arm bumpers (cost me like $6.00 at Oreillys).They are directly under the spring eyes in the second hole of the bars .I kept trimming the snubbers (only about 3/8 of an inch) till they were touching the spring with me in the car ,but not compressed.Seemed to work well .I also used a flat plate with 2 holes drilled in it to go between the spring and the bars at the rear clamp location behind the axle with a U bolt ,to make it fit snug .Mine are slightly nosed down on my car ,but get perfectly straight when i launch.It lifts the rear off the car as well as the front ...
