By installing this part you are accepting full responsibility and liability for proper wheel and tire fitment after installation.
It is the installer’s responsibility to properly align the vehicle before use. Using a wheel tire fitment combination that results in any contact from the tire and/or wheels with the new installed ReadyLIFT® upper control arm or inner fenders at any point including full steering lock will void the Ready-LIFT® warranty and may result in failure of the ball joints. Failure to do so may cause damage to your vehicle and/or injury or death to the driver and passengers.
Final Checks & Adjustments
Post Installation Warnings: Once the vehicle is lowered to the ground, check all parts which have rubber or urethane components to insure proper torque. Torque wheels to factory specs. Move vehicle backwards and forwards a short distance to allow suspension components to adjust. Turn the front wheels completely left then right and verify adequate tire, wheel, brake line, and ABS wire clearance. Test and inspect steering, brake and suspension components for tightness and proper operation. In-spect brakes hoses and ABS lines for adequate slack at full extension. Failure to perform the post in-spection checks may result in vehicle component damage and/or personal injury or death to driver and/ or passengers and void your warranty. Test drive vehicle and re-check the torque of all fasteners and re-torque wheels on vehicle.
Wheel Alignment/Headlamp Adjustment:
It is mandatory to have a proper and professional wheel alignment performed by a certified alignment technician. Align the vehicle to factory specifications. It is mandatory that your vehicle alignment be checked after any off-road driving. In addition to your vehicle alignment, for your safety and others, it is necessary to check and adjust your vehicle headlamps for proper aim and alignment.
Vehicle Re-Torque and Safety Inspection:
Upon completion of all services and adjustments performed on your vehicle, and within 50 miles of driv-ing, check to ensure all fasteners and hardware are properly torqued to specification as noted in the vehicles factory service manual or the torque chart included.
