After installing a 2.5L Terra-Flex lift on my 2-door JK, the steering was VERY lively. She'll dance like a ballerina all over the street. I wanted it to calm down and help with the journey. I was very "skeptical" about how much it would change the ride. I didn't want to spend $200 on Maybe. I bought them for $89. If I was going off-road or having trouble driving a Jeep, I would come up with a more powerful solution. They go easily, I installed them on the outgrowth (no bushings). Turn off all wheels and go. Used AVE directions as Rubicon directions SOSUT. You have to cut the screw on the passenger side, I don't know who has the strength to rip off the exhaust pipe. Save yourself a penny, visit Ace and buy a new screw for both ends. M12 - 90mm length - 1.50 thread fits factor screw. If you have some time. Torque wrench and I want to save some money. It's an easy 2 hour install and well worth it.
