Modifications needed to fit the chevy 1500 crew cab !
The aircell was all it was described and it will fit the 2008 chevy crew cab but the original bumper cups need to be removed to allow 1/2'' free space between the aircell and the axle pad to allow for a normal ride while unloaded . I decided to remove the cup with a grinder and that allowed the 1/2'' free space unloaded .possibly there is a different aircell that will fit without modifications. I pulled a 16' steel enclosed trailer 400 miles and had no sway or sag ! The aircell worked great
