rear shock mounting question

rear shock mounting question - 12/03/12 07:28 PM

I have an older alston chassis roadster with a ladder bar rear suspension. my question is this..the rear shocks are mounted on the
front of the rear end, they are double adjustables and I would think that if they were mounted on the rear of the rear end, they would work better, like the pivot axis would be moved back and allow more
functionality. Would it be better to have them mounted on the back side? also it would free up room to install an anti-roll bar, any thoughts on that also, some people say not to install an anti-roll on a ladder bar suspension, but I would think it would still work...Thanks for any info.

With a ladder bar there isnt much of a reason to install the antiroll bar...the suspension by design doesn't have much roll to it....the shocks would work better behind the rear end....

I agree that the shocks will work better mounted on the back but also think the antiroll bar will help stabalize body pitch and roll under acceleration with any suspension.They can also act as a tuning devise for preload.

If you move the shocks to the rear you MIGHT need softer
springs ... its a ratio so if you figure the ratio
to where they mount now then figure the ratio to
where they would mount on the rear side then you can
determain the spring rate.... as for anti roll on a
ladder bar... if the back end (chassis, bars, or rear
end itself) is flexing then yes a anti roll will help
but by the design the bars and rear end should be a
solid piece and shouldnt be moving from one bar to
the other

I had figured I would need lighter springs, luckily I have a new set of 90lb. ones I can try, I'm going to move the shocks, it cant hurt, I'm still on the fence about the anti-roll though, It was probably the best thing I ever did to my old car, but that was a 4 link, great tuning tool as well, thanks for the info

I wont build a 4 link set up without a anti roll
