has anyone tried using TJ coils on their JK? as long as they are the same diameters and fit in the retainers, does anyone see any problems with this? maybe they wouldnt give as much lift or as good of a ride since they might be different spring rates. if they fit, it might be a cheaper option for lifting your JK since TJ parts seem to be less expensive. just a thought, and curious if anyone else has tried it or considered it.

 

I believe there is a thread on this already. Can't remember the exact outcome, it was doable, but there were some issues.

 

i searched, but havent come up with any results. maybe im missing it?

 

I would think the spring rate would be different, specialy on a 4 door. It would sag HARD

 

iI used 4" Pro Comp front coil springs that were marketed as being for a TJ. I actually got 4 3/4" of lift out of them. Only reason I'm no longer using them is because I upgraded to 6" coil springs.

The reason I went with the TJ springs was because I only got 3.5" out of a 4" Pro Comp coil spring that was marketed for a JK.

Pro Comp is the one who actually recommended this set up and it worked fine for me....
