delivering your oil

here is the question...should you put slapper bars on a mopar? i was laughed out of the forum 5 years ago when i asked this question, but since then several drag racers have told me that traction bars work better than adjustable pinion snubbers. what is the consensus here?

if i was going to add a set, i'd use these ansen ground grabbers:

They get one more chance and they wil come off. Right at th etrack as a matter of fact. [IMG]http://i66.tinypic.com/pui5j.jpg[/IMG] Coming soon!!!!

Mopar always claimed that their springs were biased side to side and the muscle cars had longer front segments to minimize wind-up. Fine - for the stock tires! But as soon as you stuck some different rubber on the rear that changed things. Now you had the option of a s/s spring, an adjustable snubber or both. Let's face it, a) the springs weren't cheap and b) the snubber was either "on" or "off", meaning to make it plant the tires it pretty much had to be touching the floor and that gave you a lousy ride if you left it there. The slapper bars were a different animal, relatively inexpensive and they could be "tuned" such that they wouldn't do anything until you "got on it" and the springs started to wind up. So my opinion is if they work for your Mopar, they belong on it.

Springs, shocks, pinion angle, drive height, weight transfer, tire compound, etc, etc. But not slappers. And, to be honest, the only thing that pinion snubbers ever did for me was stop the rear U-joint from being twisted out when I had poor rear set-ups way back when. Master, again and still

Slappers typically hit the leafs just aft of the main eye, right in the weakest part of the spring. If the are doing that, good chance your going to bend your main leaf as it trys to lever the car's body up. Think of it this way, would you use a floor jack in this spot? That's what slappers are doing.

CalTrac's obviously work and they are slapper bars that were refined to a fully functioning level. The "poor man's 4-Link" as one could say. They basically reapply the wind-up forces into a downward motion for the axle. And one of the reasons the old Direct Connection manuals pumped up the P-snubber and rejected the slapper bars was to sell their own product. R.I.P.- Gary "Coop" Davis 02/09/68-05/13/04

They keep the pinion from walking up the ring gear. Like this: Traction bars stop it and snubbers stop it. One stops it from the center and one stops it from the outside. The reason traction bars are frowned on in the Mopar ranks is because Mopar sells a snubber. Reason two is that a lot of traction bars are built for Brand X and therefore extend beyond the front shackle. In fact a lot of traction bars are 21 inches or better but the front spring segment is 20 inches for A-Body and as long as 24 inches for the Barges. I believe Mopar Performance also sold clamps for the front spring segments to stiffen the front segment up. So yes. If you're getting wheel hop then traction bars can and will work. The only thing about traction bars is that some of "Those Guys" have been known to twist their housing on launch.

I just assumed they were made to advance to the next screen as part of a slide presentation or something like that. I wonder how many people now have their traction bars sticking out the back thanks to me.

It looks like the front of the car would be to the right of the graphic (we're looking at the right side of the car in the diagram), the rear leaf spring shackle is on the left side of the graphic, at the back of the car.. it looks like the tire is rotating clockwise, moving the car forwards... looks correct to me.

Wrong! When you look at this picture, the pinion is going towards the ground, that is the opposite of what happens. When you accelerate the pinion will go in the opposite direction, or up.

On a well set up leaf spring car, a pinion snubber is a band aid at best. Great for propping the door of the shop open for a breeze. Clamp the snot out of the front segments and the snubber isn't even needed.

I dont mind the snickers about the traction bars on a mopar thing,it works for me,with out them it goes up in smoke and has some wheel hop with 12" rim and a 29x15x15 M/Ts that is not good. with the lift bars it hooks out the hole and no spin or hop from the alxe. i would run the ansen ground grabbers or ssm lift bars not the cheap autozone/lakewood slapper bars for chebbys run what ya brung Last edited by scratchnfotraction; 05/01/12 09:39 AM.

They do make the ride a tad rough... I was thinking of trying them on the Charger as they are a lot cheaper then Cal-Tracs
