Fox Coil overs on a Rockwell jeep

chasensun · Jan 17, 2013

I need some help with my coil overs. The nitogen is low in them and I've tried reseaching what pressure to run them at. All I can find is a 200 psi max is this accurate or can I put more in them. They are 2" 16" Fox coil overs. Any adv I can get I will appreciate it. Rockwell YJ on 47" ltbs so its a heavy one. Thanks

All the pressure is for in a coilover is to pressurize the oil. It does very little to affect spring rate or damping.

Are you trying to accomplish something else by adding more pressure?

What TBI said is right, I've got a Rockwell rig also that is pretty heavy, 200 psi is all I have in my kings.Your springs and Valving is what you need to play with if your having roll issues.If that's the problem post up your spring rates and I will check it against mine.

Thanks for the input! It seemed like the shocks were too soft and collapsed too easy. I checked the pressure and it was 150 psi and I couldn't get more in it. After researching I found the shock had to be completeley out with no load to increase pressure. Again thanks for the input.
