I use standard leaf setup on a camaro. Does anyone have any experience with sliders. Also I have heard you can setup your rear spring mounts so they can be adjusted as weight jacks. any info on this would be greatly appreciated.......thanks

sliders are the best...

90-10 shock on top.

75xracer: I'm driving a smiliar car, an early 70s Malibu full-framed car, 3200#s, similar front spring rates (weights?).When I bought the car, it had matching (2 AFCO 20228s)multi-leafs on rear.
I raced it a same track where previous owner raced it. I experienced bad push. As soon as I changed LR leaf to heavier rate (AFCO 20228HD on L, 20228 on R), no push, won heat race 1st time out.

Curious as to what's the reasoning behind moving leaf (assuming y'all are running multi-leafs) forward? What's the proper method for doing this? How far forward? etc etc

#1-Lets get this outof the way. AFCOS suck. I bought five sets of the same rate because I was suspicious of their quality. Out of five sets the ride height was different on all five,a TWO inch swing, I dont know about you but I dont want to have to worry about new parts being good or not. I can feel my springs losing rate or hook and I may have to change at the track and it is hard to find level ground at the track. Dont run sliders run shackles they are cheaper and way less maintenance. Dont out think yourself on this leaf spring deal.

Will a 90/10 shock (dampener) really help on a leaf spring car? Couldn't you achieve the same thing by adding a leaf or 2 to the left side? We're having a discussion with the tech guy about allowing a 90/10. He thinks it really won't help on a leaf car. You see, the new rules say "ONLY 4 shocks per car and no torque absorbing devices" Thanks

i believe what you're refering to is a housing floater. competition engineering makes them for drag racers using ladder bars with leaf springs. they're available at summit for $96.00 a pair.

I dont get the sliding leafs forward, ive raced with leafs for 8 years. and it was my understanding from landrum, that the front of the leaf is the trailing arm, and the back is the spring, which makes up most movement and has the rating..

moving leafs foreward will stiffen spring wrap up under acceleration and soften the heck out of the spring i would think?????

why not just add a half leaf to the front, to stiffen it on acceleration, if its hopping??

you are correct, however, as shipped the front of the spring is more of a spring and less of a trailing arm than some might like.

sliding leafs forward will soften the rear a little more than it stiffens the front so adding a leaf to the front would seem to be the way to go. I find doing both and/or upping the rate of the base spring to be a good solution.
