ReadyLift® (Part# 66-2515 & 66-2516) Installation Instructions

SAFETY WARNING:ReadyLift Suspension Inc. recommends this system be installed by a professional technician. In addition to these instructions, professional knowledge of disassembly/ reassembly procedures and post installation checks must be known.

PRODUCT SAFETY WARNING:Modifying your vehicle ride height may result in the vehicle handling differently than a factory equipped vehicle. Extreme care must be used to prevent loss of control or vehicle rollover.

Failure to drive your modified vehicle safely may result in serious injury or death. ReadyLift Suspension Inc. does not recommend the combined use of suspension lifts, body lifts, or other lifting devices. You should never operate your modified vehicle under the influence of alcohol or drugs. Always drive your modified vehicle at reduced speeds to ensure your ability to control your vehicle under all driving conditions. Always wear your seat belt.

Pre-Installation Notes

1. Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/reassembly procedures of OE and related components.

2. Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.

3. Larger rim and tire combinations may increase leverage on suspension, steering, and related components.

When selecting combinations larger than OE, consider the additional stress you could be inducing on the OE and related components.

4. Post suspension system vehicles may experience drive line vibrations. Angles may require tuning, slider on shaft may require replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced.

5. Secure and properly block vehicle prior to installation of ReadyLift Suspension Inc. components. Always

wear safety glasses when using power tools.

6. If installation is to be performed without a hoist, ReadyLift aSuspension Inc. recommends rear alterations first.

7. 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 attitude. Always measure the attitude prior to beginning installation.

POST-INSTALATION WARNINGS

1. Check all fasteners for proper torque. Check to ensure for adequate clearance between all rotating, mobile, fixed, and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floor boards and wiring harness. Check steering gear for clearance. Test and inspect brake system.

2. Perform steering sweep to ensure front brake hoses have adequate slack and do not contact any rotating, mobile or heated members. Inspect rear brake hoses at full extension for adequate slack. Failure to perform hose check/ replacement may result in component failure. Longer replacement hoses, if needed can be purchased from a local parts supplier.

3. Headlight adjustment is highly recommended.

4. Re-torque all fasteners after 500 miles. Always inspect fasteners and components during routine servicing.

Tire and Wheel Fitment

For 35” tires: 35x12.50 Mounted on a wheel no wider than 9.5” with 0 offset or 5.25” backspacing.

For 37” tires: 37x12.50 Mounted on the factory wheel or on a wheel no wider than 8” with a +35 offset or 6” backspacing. Please note that with this fitment the tire will rub a little at full turn on the radius arm.

You will also need to pull the inner fender liner back with both of these fitments.

The best way to accomplish this is to install the ReadyLift® inner fender liner support kit. Drill an 1/8” hole on the inner lip of the fender liner and an 1/8” hole on the underside of the body. Using the self-tapping screw and speed clip provided attach the bracket to the fender liner then attach the other end to the body. See photos below.
