Sure, there are guys that run this set up... but I have to ask.... why. To me its a redundancy thing. Lets break it down, the front segment of the spring does the same job as the ladder bar... it holds the axle in place and lifts the body but the spring has possible rap up where the bars dont. Next is the rear portion of the leaf spring... this is the part that allows the body to move up and down.... and hold the body up. This is the equivalent to the coil on the shock.... they are equal but the leaf weighs more. Shocks... they both do the same job but the coil over shock has a couple of alum parts to hold the spring Over all.... why run both it would be heavy....

Heres the thing , If we go coil over I have to step up from super stock to pro stock , we tried heavy springs in front of axle with lighter springs aft of axle with sliders , bent the hell out of the springs so we went heavyer and truck wont stay on the ground,took out some spring & we added ladder bars and rear is too stiff , bars fighting leafs but best so far, the floaters look like they are made for spring under axle we are over axle? if we flip the floaters upside down we raise the rear up too high? trying to keep the weight as close to the ground as possible
are we talking drag racing or mud bogging?

once you put the ladder bars and floaters on the leaf springs merely hold the car up.this will work fine especially on the street.leaf springs alone can wrap up and cause wheel hop and other issues.some times slapper bars can help . with ladder bars the rearend wants travels in a different arch then when bolted solid to the leaf springs,thus the need for the floaters.they allow the rearend to move without binding. but leafsprings are heavy and do not allow the chassis tuning advantage of coil overs.coilovers also require some sort of track locater to control side to side movement which sometimes can cause street driving problems.not an issue on a drag only car i have done it both ways with no problems although i give the ladder bar/coilover set up the ![](/ubbthreads/images/graemlins/thumbs.gif)

Looks like you will be making your own floaters. Or if you can have the same IC of the front spring eye and the front heim joint on the ladder bars(same fore and aft and vertical height) you would have a common IC and wouldnt be fighting each other ![](/ubbthreads/images/graemlins/wave.gif)

are you saying to shorten the ladder bar to the same lenght as the leaf mounting point?

Now theres a thought, The springs can be any lenght as long as long as thier not coilover , if the front of the spring is the same lenght as the ladderbar even if they are different hights the arc should be the same?

The issue of 2 IC points is they would fight each other, the farther apart the greater the fight, try to get the same IC points. Also does it really have to be a spring, YEARS ago I clamped a steel bar to my leaf spring to stiffen it up for traction, it worked great, took out all of the flex in the front segment. Like I said earlier the front just holds the rearend in place and gives lift to the body..... can you just put a steel bar in, in place of the spring, clamped or welded to the rearend and a front eye welded to the bar.... just thinking out loud ![](/ubbthreads/images/graemlins/wave.gif)

my pops car has been 1.19 60' 8.30 @ 170 3400lbs, 10.5w's. On ladder bars, floaters, and factory leaf springs. It does work.

you can throw enough HP at something and still go fast. but what is the reason for running a set up like that when there is better ways to do it? is it because of the class, to save a few bucks? etc. just curious?

You need a set of sliders on your set up instead of a floater kit,IMHO ![](/ubbthreads/images/graemlins/scope.gif) We used them years ago on a drag car with ladder bars, it would hook up in a mud pit in the middle of a rain storm ![](/ubbthreads/images/graemlins/whistling.gif) It least it seemed like it would ![](/ubbthreads/images/graemlins/thumbs.gif)

We have sliders @ the back of leafs , they let the rear end of the leaf flex a little but still too stiff , yanked the leafs out this morning to get some clean measurements , going coilover would be really easy but that boots us out of class , I can build floaters for spring over axle or change out to a longer spring to match my IC< MR P > or I can go coil spring like a chebby and stay in my class? Got 2 weeks to figure it out , I think the 4 links work with leafs cause of the 4 hiem joints pivot , the ladder bar is like a solid truss , not much give ,I have never raced at Lee Co. , they run mostly hill & hole , they have a flat track but only ran rails last year, if they open the flat up we will go its about 2hr drive. Well now my mess is apart so keep the ideas comming ![](/ubbthreads/images/graemlins/beer.gif)

you see this car.. ![](http://img.photobucket.com/albums/v506/smokinwoody/mikes56.jpg) very old school gasser..uses the stock leaf suspension with long set of ladder bars and NO floaters.. thats what they did back then and thats whats still on this car...he uses a BOP rear(saginaw 9 1/4") that uses a welded seamed axle housing... the two different motions or archs of rthe leaves and the ladder bars caused the seam to split open on the axle housing... just so you know what can happen without a floater to allow the axle to rotate with two oposing forces... I did fi the rear for him but he was missing pieces from his floater kit so I beefed the axle housing and the ladder bar connection points till he gets the parts or revises the rear suspension.. that 56 goes high nines and I cant figure out how it still passes tech...

I'm sure it has enough IC before it binds up that allows it to hook.... but then again its busting up parts doing it ![](/ubbthreads/images/graemlins/wave.gif)

If you wanted to change your system some you could do like the old pro stockers, they used a leaf and a bar on top of the axle that acted like a four-link. I'm sure someone has a pic of that set up ![](/ubbthreads/images/graemlins/wave.gif)

That car was built in 95, It is just simple, it works. The car would hook at test and tune like it would on raceday. When our competitors were changing 4-link bars, checking how far the zip tie moved up on compression and making shock ajustments we were setting in the trailer talking and having a good time. Low Mantinence! And I know when you get a 4 link car set-up you don't have to mess with it but you don't even have to go through getting it right.
oh OK, good to know thats a better set up than a 4 link. heck I may change mine ![](/ubbthreads/images/graemlins/thumbs.gif)

I seen a stock elim. car set up this way. The back was bolted on to the plate that holds the spring and the front was a pice of tubing that slid inside of anouther tube that was mounted to the front spring eye bolt by 2 clips welded to the outer tube. The stockers have to have a bolton suspention. This car ran 1.30 60s and 10.00 with this setup. On your truck I would think the spring was on tob of the rear, so you would have to find a way to mount it underneath. You might try a leaf link suspention with a bar going from the top of where the rear mounts to the spring to the front frame at the spring mount. good luck and I did see where you are keeping the springs as per class rules ![](/ubbthreads/images/graemlins/biggrin.gif)

Well, Thats a Great example as to how well leaf springs and ladders can hook.
A 1.36 60 ft. hook should be good for a 10.0 run.
That car is certainly Hooking but not Booking for its 60 ft, ET. Still, Overall not bad IMO. For its ET its a Hook monster, mike ![](/ubbthreads/images/graemlins/thumbs.gif)

ive got a 78 dodge 4x4 full size. using a ladder bar with a floater and drag shocks it works great in the drags and also in the pits. my bars mount at the center of weight on the truck. it is like the kit from jegs (not the CE kit) but adapted to go over the axle. we also have a truck with the CE kit. i think you can stay lower that way. a few other guys brag how they are running the ladder bar with no floater or slider.... but those trucks wheel-hop like crazy!!! also seen it done with the spring slider but the guy who built mine prefers the floater. i will try to get some pics. BTW your bars look a little short.

The bars are 33" we had long bars and had too much lift , I want to keep the front wheels in the mud , wheelies are fun but too hard to recover from if your not dead on, The CE sliders we have arent enough , I will check jeggs for the floater kit thanks ![](/ubbthreads/images/graemlins/thumbs.gif)

Was thinking about this why do you nead the front half of the spring, just put the ladderbars in the front and a leaf from say the back half of the cal track single leaf spring and a watts link or a diagnal link. ![](/ubbthreads/images/graemlins/biggrin.gif) So what you think
We just put 2 leafs back in down from 4 & have around 2" of down travel now thats not too stiff, than it starts to bind and stiffen up , with the 4 leafs you could not move the back of the truck down at all, I am thinking of pulling the last spring and trying it with only the main spring ,gota check rules
