Im sure its been gone over before but i want to know how happy everyone is with the RK 2.5 stock mod kit. I have been thinking about getting the RC 3.5 series 2 lift but have heard some bad stuff about it. Springs sagging ect. My jeep is and will be driven on the highway going to and from work. Sometime longer distances as i drive a few hundred miles to go to work sometime. I want to run 35s on my stock wheels.
