• Full length replacement coil springs add additional ride height while maintaining ride quality.
• Heavy-duty track bar re-centers front axle, adds strength and limits lateral movement.
• Radius arm drop brackets correction position front axle allowing use of the factory radius arms.
• Rear lift block and longer U-bolts for easy installation and level stance.

Important Note: 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. This lift will require replacing your truck's factory rear block to achieve a level stance. Exhaust modification may be required to clear the front driveshaft on gas models. Two-piece rear drive shaft? Add a carrier bearing drop kit to reduce post-lift driveline angles and avoid / eliminate driveshaft vibration.
