3.5” Lift Kit
INSTALLATION INSTRUCTIONS MAKE SURE YOU HAVE THE CORRECT LIFT FOR YOUR VEHICLE:
Double check the Year, Make, Model, Lift Height and KIT Part Numbers.

Prior to beginning the installation, OPEN the boxes and CHECK the included components compared to the Parts Breakdown. Check all parts and hardware in the box with  the parts list below. Be sure you have all needed parts and know where they install.
IF you find a packaging error, contact SUPERLIFT directly. Do not contact the dealer where the system was originally purchased. You will need the control number from  each box when calling; this number is located at the bottom of the part number label and to the right of the bar code.

How to Read the Kit Breakdown Charts:
The ‘KIT BREAKDOWN’ lists Part Numbers, Quantities & Part Description of the individual components & Hardware Bags that are included in each box. The ‘HARDWARE BREAKDOWN’ lists the Part Numbers, Quantities & Part Description of the individual components.
THANK YOU FOR CHOOSING SUPERLIFT FOR ALL YOUR SUSPENSION NEEDS!!

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 beginning, inspect the vehicles 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 needed parts and know where they install.

NOTES:

• Do NOT install this suspension system in conjunction with any other type of aftermarket or fabricated components to gain additional suspension height.
• Do not fabricate any components to gain additional suspension height.
• Prior to attaching components, be sure all mating surfaces are free of grit, grime, grease, undercoating, etc.
• Front end alignment is necessary.
• Tool and Wrench/Socket size is given in brackets [ ] after each appropriate step.
• A foot-pound torque reading is given in parenthesis ( ) after each appropriate fastener.
• Always wear safety glasses when using power tools.
• 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 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 brake system. 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. Perform head light check and adjustment.

WARNING…
It is ultimately the 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 factory, consider the additional stress you could be inducing on the factory and related components.
Stock 17” & 18” wheels WILL fit back on the vehicle once this suspension system is installed. ALL tire & wheel combinations should be test fit prior to installation.  Some minor trimming maybe required. Some minor trimming will be required with certain wheel/tire combinations. Trimming will normally include the bottom edge of the inner fender shrouds and/or lower corner of front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower tires will reduce/eliminate trimming required.

IMPORTANT DISCLAIMER: The provided tire/wheel recommendations are approximate. Actual dimensions of a given tire size can vary considerably from one brand  to another. Manufacturers’ wheel offset and backspacing measurement points are not always consistent. Backspacing greatly impacts tireto-fender clearance when turning.
Wheel width and backspacing influence whether the tires protrude past the fenders, and to what extent.

46. When the tires and wheels are installed, always check for and remove any corrosion, dirt, or foreign material on the wheel mounting surface, or anything that contacts the wheel mounting surface (hub, rotor, etc.). Installing wheels without the proper metalto-metal contact at the wheel mounting surfaces can cause the lug nuts to loosen and the wheel to come off while the vehicle is in motion.
47. Lower vehicle to the floor.

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 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.
