Rubicon Express RE1454 4.5" Extreme-Duty Leaf Spring for Jeep YJ

You will love the ride quality with these. night and day difference from the RC springs.

Installed these in a spring under configuration on my 93 YJ. Springs ride well & flex very nicely on the trail. Couple things to warn you about: 1) It is very easy to experience shackle inversion with these springs due to their high arch. I bent one on my 1st trip out on them & they will invert every wheeling trip unless you fabricate a shackle stop (easy fix if u can weld at all, just weld a decent thickness lag bolt or steel dowel perpendicular to the shackles line of movement on the back of the factory spring hanger or wherever u want the shackle to stop). 2) if u plan to run teraflex revolver shackles with these springs & your hangers are in the factory locations the shackles will drag on the frame in the front under certain situations & will clap against the frame in the rear again due to the springs high arch & shorter eye-to-eye measurement. The clapping in the rear when driving over bumps isn't a big deal but can be annoying. The dragging in the front on the D/S is a different story as from what I could see the shackle can jam & bind against the steering box brace & hardware causing damage. I chose to not run the revolvers in the front due to this. 3) I had to cut the military wrap off of the front of the spring in order to get clearance between the spring & shackle cross brace. This all depends on shackle design (if I remember right, mine are Rugged Ridge & definitely provide 5/8" lift). Overall, I would recommend these springs to a friend but I would also share my experiences with them so that they could make an informed decision. Great springs, they just come with some extra considerations.

I just read a lengthy review here and I have to tell everyone that if you have to modify these springs you installed them backwards. The military wrap goes into the frame, the other end goes to the shackle. Look for pdf instructions on similar springs through the rubicon express website.
