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
Air lift air cell on GMC Sierra 1/2 ton.
This is a great product. The first day I had them I loaded a single layer of granite boulders in the truck bed and it rode level as if there was no load at all. I used both spacers for max height, and leaves about 1.5" clearance between the air cell and the axle.
Kit came the bump stop and cup quality is good the hardware included was low quality I downloaded the installation guide off of the air lift web site no biggie, the spacer didn't fit my truck correctly had to pick up some different hardware from the CAT dealer, bolts good to 150,000 psi and different grade 8 washers to correct the fit. The air cells perform as they advertise my truck was very stable and handled well with our camper in the back.
