Hey has anyone heard of doing this or having to do this with a 4" lift that has the adjustable rear control arms. In the advertisement its new coil mounts and the ad states that it allows relocation of rear coil mounts after axle pinion has been raised ( after fitment of a CV driveshaft). Not sure if this is needed or if anyone has done it.

 

I used rock krawlers coil shims to straighten out my rear coils. They are a lot cheaper and easier to install. I didn't want to cut off my rear mount if I didn't have to.

 

I have a RE 4 1/2 inch lift and my rear coil springs were bowed after the pinion angle was adjusted. There is not enough material on the stock spring perches to cut them off and then weld them back on in the correct position. I used the JKS spring perches to align the springs, good product and easily corrected the bowing of the springs.

 

nice post RubiRed...that about answers that
