Installation Instructions 44-2157 (Covers All F150 MLS Complete Kits)
Please read Instructions thoroughly and completely before beginning installation.
Installation by a certified mechanic is recommended.
ReadyLIFT® Off Road Suspension is NOT responsible for any damage or
failure resulting from improper installation.
Safety Warning: Suspension systems or components that enhance the on and off-road performance of your vehicle may
cause it to handle differently than it did from the factory. Extreme care must be used to prevent loss of control or vehicle rollover during abrupt maneuvers. Always operate your vehicle at reduced speeds to ensure your ability to control your vehicle
under all driving conditions. Failure to drive safely may result in serious injury or death to driver and passengers. Driver and
passengers must ALWAYS wear your seat belts, avoid quick sharp turns and other sudden maneuvers. ReadyLIFT® Off Road
Suspension does not recommend the combined use of suspension lifts, body lifts, or other lifting devices. You should never
operate your vehicle under the influence of alcohol or drugs. Constant maintenance is required to keep your vehicle safe.
Thoroughly inspect your vehicle before and after every off-road use. It is the responsibility of the retailer and/or the installer
to review all state and local laws, with the end user of this product, related to bumper height laws and the lifting of their vehicle before the purchase and installation of any ReadyLIFT® products. It is the responsibility of the driver/s to check their surrounding area for obstructions, people, and animals before moving the vehicle. All raised vehicles have increased blind spots
and damage, injury and/or death can occur if these instructions are not followed.
Installation Warning: All steps and procedures described in these instructions were performed while the vehicle was properly supported on a two post vehicle lift with safety jacks. Use caution during all disassembly and assembly steps to insure
suspension components are not over extended causing damage to any vehicle components and parts included in this kit.
Included instructions are guidelines only for recommended procedures and are not meant to be definitive. Installer is responsible to insure a safe and controllable vehicle after performing modifications.
ReadyLIFT® Off Road Suspension recommends the use of an OE Service Manual for model/year of vehicle when disassembly
and assembly of factory and related components. Unless otherwise specified, tighten all bolts and fasteners to standard
torque specifications listed within the OE Service Manual, or as referenced in the torque specification list provided in these
instructions.
Suspension components that use rubber or urethane bushings should be tightened with the vehicle at normal ride height.
This will prevent premature wear or failure of the bushing and maintain ride comfort. Larger tire and wheel combinations may
increase leverage on suspension, steering, and related components. Due to payload options and initial ride height variances,
the amount of lift is a base figure. Final ride height dimensions may vary in accordance to original vehicle ride height. Always
measure the vehicle ride height prior to beginning installation.

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. Inspect brakes hoses and ABS lines for adequate slack at full extension. Failure to perform the post inspection checks may result in vehicle component damage and/or personal injury or death to driver and/
or passengers. Test drive vehicle and re-check the torque of all fasteners and re-torque wheels on vehicle. Re-adjust headlamps.
Vehicle Handling Warning: Vehicles with larger tires and wheels will handle differently than stock
vehicles. Take time to familiarize yourself with the handling of your vehicle.
Wheel Alignment/Headlamp Adjustment:
It is necessary to have a proper and professional wheel alignment performed by a certified
alignment technician. Align the vehicle to factory specifications. It is recommended 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 driving, 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.
