SUPERLIFT 2021 Ford Bronco 4WD 2.5 Inch Lift Kit Instruction Manual

SUPERLIFT 2021 Ford Bronco 4WD 2.5 Inch Lift Kit

Product Information

The 2021 Ford Bronco 4WD comes with a 2.5 Inch Lift Kit, designed to provide additional suspension height. This lift kit is manufactured by Superlift, a trusted brand for suspension needs.

Installation Requirements

• Installation should be performed by a professional mechanic with knowledge of disassembly/reassembly procedures and post-installation checks.
• Prior to installation, it is important to inspect the vehicle’s steering, driveline, and brake systems. Pay close attention to suspension link arms and bushings, sway bars and bushings, tie rod ends, pitman arm, idler arm, ball joints, and wheel bearings. Check for stress cracks in the steering sector-to-frame and all suspension-to-frame attaching points. Repair or replace any worn parts.

Installation Instructions

1. Double-check that you have the correct lift kit for your vehicle by verifying the Year, Make, Model, Lift Height, and KIT Part Numbers.
2. Read the provided kit breakdown charts to understand the Part Numbers, Quantities, and Part Descriptions of the individual components and hardware bags included in each box.
3. Before starting the installation, read the instructions several times to familiarize yourself with the process.
4. Inspect all parts and ensure you have everything needed for installation.
5. Follow each step of the installation instructions carefully.

Precautions and Recommendations

• After installation, check all fasteners for proper torque and ensure adequate clearance between rotating, mobile, fixed, and heated members. Verify clearance between exhaust and brake lines, fuel lines, fuel tank, floorboards, and wiring harness. Check steering components for clearance.
• Perform a test and inspection of 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. Replace hoses if necessary.
• Perform a headlight check and adjustment.
• It is the buyer’s responsibility to have all bolts/nuts checked for tightness after the first 100 miles and then every 1000 miles. Regularly inspect the steering, suspension, and driveline systems, as well as wheel alignment, at least every 3000 miles with the help of a qualified professional mechanic.
• When selecting larger rim and tire combinations than factory specifications, consider the additional stress that may be induced on the factory and related components.

Note: The provided tire/wheel recommendations are approximate. The 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 fitment.

INFORMATION

MAKE SURE YOU HAVE THE CORRECT LIFT FOR YOUR 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’s 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.

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 are 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 with the original vehicle stance.

BEFORE YOU DRIVE

• Check all fasteners for proper torque.
• Check to ensure 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 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 the 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 may be 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 the lower corner of the front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower tires will reduce/eliminate the trimming required.

IMPORTANT DISCLAIMER:
The provided tire/wheel recommendations are approximate. The 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.

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.
