Important Notes
- Although extremely rare, front and/or rear drive-line vibration may occur and require drive-line modification.
- This kit is not designed for dually models, but may be easily adapted to accommodate your truck. Please contact customer support and they will help you find a solution.
- This lift will require replacing your truck's factory rear block to achieve a level stance; total height gained will vary depending on the size of the factory block.
- Exhaust modification may be required to clear the front driveshaft on gas models. See installation instructions for more information.
- Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid/eliminate driveshaft vibration.
