About this kit
3.5-Inch Lift Kit, fitment-checked
Rough Country 21800 raises the 2021–2024 Chevy Tahoe 4WD by 3.5 inches while keeping the factory Adaptive Air Ride system working through all its height settings. It is built specifically for air-ride trucks: Z71 models with Adaptive Air Ride are covered, and Z71 models that also carry Magnetic Ride Control are not. Forged aluminum upper control arms with pre-installed POM ball joints do the front work.
This 3.5-inch lift kit for the 2021–2024 Chevy Tahoe 4WD is aimed squarely at trucks with factory Adaptive Air Ride, and it keeps every factory ride-height setting functional. Forged aluminum upper control arms with pre-installed POM ball joints handle the front; strut spacers and ride height sensor relocation brackets go in at both ends. Rough Country lists the job at 5-6 hours, with minor trimming needed. Wheels must be 20 inches or larger, and the published tire chart runs from 275/65R20 on factory wheels up to 33x12.50R22 with trimming. Shipping weight: 25.5 lb.
