Important notes

• Requires minor cutting and drilling during installation.
• Factory rear overload springs must be removed on equipped models.
• Does NOT fit dually models due to u-bolt design variances.
• Gas models may require exhaust modification for driveshaft clearance.
• Does NOT work with factory wheels. Models equipped with factory 17-inch wheels must use 17-inch or larger aftermarket wheels due to larger calipers and rotors.
• A torsion bar removal tool (RC 1067) is recommended for ease of installation.
