Can anyone recommend any good sources of info on the various rear suspensions currently being used on mods? I am looking to get a better understanding of some of them especially the mono leaf and multi leaf setups. Any good sources of info and or pics and diagrams? I am planning on getting the Steve Smith book on mods but was looking for other sources if there is any better. I am going to be running a mod some this year and need to get a better understanding.

Chassis builders are the best source of info. Mono's run pretty good, but why would you want the extra maintenance? Get the bars and get forward bite AND be able to drive the car through the corners, not throw it through.

3 link is the easiest rear suspension to understand. most of the winning here in iowa is with a 3 link car. 3 link is my std suspension although i can and have built 4 links before.

In my humble opinion i would not spend the time fooling with the mono leaf set up.

I have ran this suspension for years and had nothing but trouble. If the coil spring sliders were not binding then the leaf spring sliders were.

And just about the time you get it dialed in the leaf springs begin to wear out which is usally about 6 to ten nights.

Believe it or not the shackles on the leaf springs work the best and dont bind as easily, as the other slider box set ups.

I would never run another mono leaf car, but if thats what you have or want to run, then Buzzard Chassis is an excellent place to talk to someone that knows and builds multi or mono leaf set ups thats all they build.

THey currently are running a mono on one side and a multi one the othere side and doing really well, there cars are tough beat.

More power to them, but I want nothing to do with a multi or mono leaf rear.

3 link or 4 bar or Z link is much better set up in my opinion.

I personally would turn the car into a 3-link they are pretty easy to maintain and alot more adjustable. ANYWAYS YOU DON'T WANT A STORAGE SHED FULL OF JUNK LEAFS. But for any reason you can't and have to run the leafs i would run the multi leafs with a lift bar.check with PRO-CHASSIS they bulid them and are pretty fast around here. We have worked on one before and know somethings about them SPRINGS LF1000 RF900 LR L31 RR L21 RIDE HEIGHTS LF 7INCHES RF 7 1/2INCHES START WITH ABOUT 115-125LB BITE ON LEFT REAR HOPE THIS HELPS

I am building two cars right now that have leaf sping setups. One with half springs and coils and the other multileaf and mono with coil. If you need more info: JP77j@aol.com
The only problem with the leaf spring is you have to throw the left one away every 6 or 7 nights but they are cheap. Most of the problem with leaf springs is you can't easily adjust the roll center. Also you give up roll steer with the leaf springs (lengthening the wheel base with eccentric on the right side is not roll steer)which means you have to slide the car around the corner loosing traction all the time. We're trying the half leafs with panhard and coils in January just to see what it'll do. Hope this helps.

i have always ran half leafs with a jbar and a dual spring touque link. i have found that this setup works real good. i run a dw8 on a rough fast 3/8th mile. you get the great forward traction of leafs with the roll center adj of a three link. i also 86ed those junk eliminators in favor of ***** jacks a year ago and have had no bind problem.
