I ordered a 2.2 perf shock stabilizer from RC when i ordered my 3.25" lift. They sent me there Hydro instead, so i called and they sent me the 2.2 perf shock, told me to keep the other one, and threw in a Rough Country Suspension Systems full window sticker. SCORE!
well the 2.2 perf shock is way way way too stiff, makes the ride crappy! i had a hard time just pulling the piston out of the shock body, i had to hook one end on to my tow hook and pull on the body to get it extended, the jeeps responce and handling went to crap vs. using the stock stabilizer.
So i have the hydro still, that i never put on, it is a lot smoother and 10x easier to pull out and push in, i may throw that on instead...
maybe the 2.2 stabilizer is designed for 40's
