I did the lift with Rough Country. Went with the 4" lift. I opted for the 2.2 shocks (their upgrade from the hydro 8000's) but am wondering if I should have went with the Nitro 9000's. 2.2 are a hydraulic shock and the 9000's are nitro charged (200psi). What are you guys running on your Jeeps. Hydraulic or nitro charged?
