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.
Engineered for 4WD Models ONLY.
Fits:

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.
If being installed on a 2009 Model, You MUST Order a #77-15-9922 Separately!!
Vehicles Equipped with a 2-Piece Rear Driveshaft, You MUST Order #9935 for the
Carrier Bearing Shims.
• 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 original vehicle stance.

INSTALLATION INSTRUCTIONS
FORM#9922.02-05202019 PRINTED IN U.S.A. PAGE 2 OF 26
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.
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.
Stock 18” & 20”Wheels Will Fit back on
the vehicle once this suspension system is installed.
ANY larger or wider tire & wheel
combination other than listed Will Require Vehicle
Trimming.
IMPORTANT DISCLAIMER: The provided
tire/wheel fitments 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 tire-to-fender
clearance when turning. Wheel width and
backspacing influence whether the tires protrude
past the fenders, and to what extent. Considering
these important factors, we recommend that
you fit-check your tire/wheel selection prior to
purchasing.

When the
tires / 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
metal-to-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.
Retighten lug nuts at 500 miles after any wheel change, or anytime the lug nuts are loosened. Failure
to do so could cause wheels to come off while vehicle is in motion.
Lower vehicle to the oor. The suspension is now supporting vehicle weight.
