flat springs plus shackle reversal = ?

If a person is using some pretty flat Wrangler springs on a CJ wouldn't a shackle reversal be counter productive? Does this make sense? What do you guys think of shackle reversals on trail only rigs (important...not important)?

Re: flat springs plus shackle reversal = ?

I run a shackle reversal on my CJ with YJ springs. I have heard that if you keep the shackle in front, like stock, It will help put more presure on the front tires for better traction. A shackle reversal will ride nicer, but on mine, if I brake hard, I can get the front fenders to rub on the tires. So far that is the only bad thing I can say about my shackle reversal.

Thanks, Ray

Re: flat springs plus shackle reversal = ?

I run shackle reversal on my cj5 with original springs. It works great. If you have arched springs Ive heard that you have to get drivshafts that have longer travel. But if you have flat springs the spring will negitve arch during articulation so the drive shafts dont need to be long travel. Others here may disagree but this is how it was in my case. I am also running SOA so my case may be different from yours

Re: flat springs plus shackle reversal = ?

a shackle reversal with flat springs (in my opnion) will of be no benifit if your looking for on-road ride quality improvement.
it's because the axle will move back during compression while hitting bumps (with flat springs and the shackle up front)
and with arched springs and shackle up front the axle will move forward during compression 1/2 the distance the lower shackle bolt moves forward. bla bla bla
i think ride quality has much more to do with good quality springs with properly valved shocks, than which end the shackle is on[img]/wwwthreads_images/icons/smile.gif[/img]

but i do like the "aproach angle" improvement and less "plowing or digging" while off-road

It's a waste *if* the springs are perfectly flat. As long as there is some arch to them, you'll see the benefits of the reversal on handling.
