INTRODUCTION

Installation requires a professional mechanic. The overall vehicle must be in excellent working

condition; repair or replace all worn parts.

Read instructions several times before starting. Be sure you have all needed parts and know

where they install. Read each step completely as you go.

NOTES:

• Prior to beginning the installation, check all parts and hardware in the box with the parts list below.

If you nd 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.

• The ball joints DO NOT come pre-greased---They MUST be greased prior to installation.

• Front end alignment is necessary.

• An arrow on diagrams indicates which direction is toward the front of the vehicle.

• A foot-pound torque reading is given in parenthesis ( ) after each appropriate fastener.

• Do not fabricate any components to gain additional suspension height.

• Prior to drilling or cutting, check behind the surface being worked on for any wires, lines, or hoses

that could be damaged.

• After drilling, le smooth any burrs and sharp edges.

• Prior to attaching components, be sure all mating surfaces are free of grit, grease, excessive

undercoating, etc.

• A factory service manual should be on hand for reference.

• Use the check-off box “” found at each step to help you keep your place. Two “” denotes that

one check-off box is for the driver side and one is for the passenger side. Unless otherwise noted,

always start with the driver side.

PARTS LIST … The part number is stamped into each part or printed on an adhesive label. Identify

FORM#3600.03-111017 PRINTED IN U.S.A. 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.

FORM#3600.03-111017 PRINTED IN U.S.A. PAGE 10 OF 10 always use as wide a tire and wheel combination as feasible to enhance vehicle stability.

Avoid situations where a side rollover may occur.
