BDS Suspension 4" Suspension Lift Kit - Chevy Trail Boss / GMC AT4 4WD

Go even further with your Trail Boss or AT4 with these 4" IFS systems. Engineered for not only offroad capability with clearance for up to 37s, this kit maintains on-road handling and has been confirmed compliant with FMVSS 126 (ESC System) standards.
