Rubicon Monotube RXJ701/RXJ702 which are really great heavy duty shocks, an option when ordering the kit and 100 times better than stock! The quality of the kit is impressive, especially the johnny type joints, intructions cant get any better, springs make the stock one's look like a joke. The old factory control arms look like weak flimsy units after you get them off and the factory rear swaybar links were plastic! If I could afford this kit I would buy it, this is how Chrysler should have built the Jeep TJ. I may even try to purchase the springs seperately to upgrade my existing cheap procomp lift which only came with lower control arms, springs, and shocks but procomps $700 price tag speaks for itself as a low end kit.
