Quadratec Maximum Duty 2.5" Coil Spring Suspension Lift Kit with Shocks Reviews
not happy with the rear shocks on this. I have lost the upper rear bushings already and only have them less than a year and the lower bushings on the rear are not holding up that great either.
Installed in May 2019. Everything was easy to put on. Four months later after a couple of 4x4 trips I noticed some bad rattling and discovered that the upper rear shock bushings had come out of the shocks on both sides separating the shocks from the tie straps. I had to make and install “shims” that slide over each side of the T strap to hold the bushing in place. I don’t know if this has happened to anyone else but I hope Quadratec does something about this product problem.
Just a word to the wise I'm shutting down my 2013 JK sport unlimited for the second time for the rear axle tracking support bracket cracking away from the Dana 44 rear axle on the on the left side. Once I can see for welding flaw etc on the Dana but twice now leads me to believe that this kit (8.0 shocks) puts an inordinate amount of tension on this bracket. Beside the 33's I run on stock rims and this lift there are no other mods. Big thing here is it's not even an off roader.
