THANK YOU FOR CHOOSING SUPERLIFT FOR ALL YOUR SUSPENSION NEEDS!

Read And Understand All Instructions And Warnings Prior To Installation Of the System AND Operation Of the Vehicle.

INTRODUCTION BEFORE INSTALLATION

Installation requires a professional mechanic. In addition to these instructions, professional knowledge of disassembly/reassembly procedures and post-installation checks must be known.
PRIOR to the beginning, inspect the vehicle steering, driveline, and brake systems, paying close attention to the suspension link arms and bushings, sway bars and bushings, tie rod ends, pitman arm, idler arm, ball joints and wheel bearings. Also check the steering sector-to-frame and all suspension-to-frame attaching points for stress cracks. The overall vehicle must be in excellent working condition; repair or replace all worn parts. Read instructions several times before starting.
Read each step completely as you go.

Be sure you have all the needed parts and know where they are installed.

• Front-end alignment is necessary.
• A foot-pound torque reading is given in parenthesis ( ) after each appropriate fastener.
• Tool and Wrench/Socket size is given in brackets { } after each appropriate step.
• Always wear safety glasses when using power tools.
• Prior to attaching components, be sure all mating surfaces are free of grit, grease, excessive undercoating, etc.
• Do not fabricate any components to gain additional suspension height.
• A factory service manual should be on hand for reference.
• 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 the original vehicle stance.

BEFORE YOU DRIVE

• 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 components for clearance.
• Test and inspect the brake system. Perform a 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.
• Perform headlight check and adjustment.

WARNING
It is the ultimate buyer’s responsibility to have all bolts/nuts checked for tightness after the first 100 miles and then every 1000 miles. The steering, suspension and driveline systems, plus wheel alignment should be inspected by a qualified professional mechanic at least every 3000 miles.

TIRES & WHEELS
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.

NOTE
Stock 17” and 18” Wheels Will Fit back on the vehicle once this suspension system is installed.

WARNING
ANY larger or wider tire & wheel combination other than listed Will Require Vehicle Trimming.

IMPORTANT PRODUCT USE AND SAFETY INFORMATION / WARNINGS

As a general rule, the taller a vehicle is, the easier it will roll over. Offset, as much as possible, what is lost in rollover resistance by increasing tire track width. In other words, go “wide” as you go “tall”; always use as wide a tire and wheel combination as feasible to enhance vehicle stability. We strongly recommend, because of the rollover possibility, that the vehicle be equipped with a functional roll bar and cage system. Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur. Generally, braking performance and capabilities are decreased when significantly larger / heavier tires and wheels are used. Take this into consideration while driving. Also, changing axle gear ratios or using tires that are taller or shorter than factory height will cause an erroneous speedometer reading. On vehicles equipped with an electronic speedometer, the speed signal impacts other important functions as well. Speedometer recalibration for both mechanical and electronic types is highly recommended. Do not add, alter, or fabricate any factory or aftermarket parts to increase vehicle height over the intended height of the SUPERLIFT® product purchased. Mixing component brands is not recommended.
