Read And Understand All Instructions
And Warnings Prior To Installation Of
System And Operation Of Vehicle.
Your truck is about to be fitted with the best suspension system on the market today. That means you will be driving the baddest looking truck in the neighborhood, and you’ll have the warranty to ensure that it stays that way for years to come.
Thank you for choosing BDS Suspension!
BEFORE YOU START
BDS Suspension Co. recommends this system be installed by a professional technician. In addition to these instructions, professional knowledge of disassembly/ reassembly procedures and post installation checks must be known.
FOR YOUR SAFETY
Certain BDS Suspension products are intended to improve off-road performance. Modifying your vehicle for off-road use may result in the vehicle handling differently than a factory equipped vehicle. Extreme care must be used to prevent loss of control or vehicle rollover. Failure to drive your modified vehicle safely may result in serious injury or death. BDS Suspension Co. does not recommend the combined use of suspension lifts, body lifts, or other lifting devices. You should never operate your modified vehicle under the influence of alcohol or drugs.
Always drive your modified vehicle at reduced speeds to ensure your ability to control your vehicle under all driving conditions. Always wear your seat belt.
BEFORE INSTALLATION
• Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/reassembly procedures of OE and related components.
• Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.
• 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.
• Post suspension system vehicles may experience drive line vibrations.
Angles may require tuning, slider on shaft may require replacement, shafts may need to be lengthened or trued, and U-joints may need to be replaced.
• Secure and properly block vehicle prior to installation of BDS
Suspension components. Always wear safety glasses when using power tools.
• If installation is to be performed without a hoist, BDS Suspension Co. recommends rear alterations first.
• 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 attitude. Always measure the attitude prior to beginning installation.

This kit is designed to work with 18x9 or 20x9 rims with 4-1/2” backspacing. Max tire size is
35x12.50 for 6” kits, 33 x 12.50 for 4” kits. Front wheel well modifaction is required to clear a 35” tire, see end of instruction sheet.
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 gear 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.
Longer replacement hoses, if needed can be purchased from a local parts supplier.
Perform head light check and adjustment.
Re-torque all fasteners after 500 miles. Always inspect fasteners and components during routine servicing.

It is critical that this hole is drilled to the correct size. Remove any burrs that could keep the rivet nut from seating flat against either side of the hole surface.
Note: If the correct drill size is not available, it is possible to drill the hole to an available smaller size and slowly grind it out to until the rivet nut fits tight.
Rivet Nut Installation Tool Assembly
3. For a 3/8” rivet nut, place the provided 3/8” SAE flat washer on the 3/8” x 1-1/2” bolt, followed by 7/16” hex nut and then a 3/8” serrated washer. Figure 1 Thread this tool assembly into the rivet nut.
4. For a 1/2” rivet nut, place the provided 1/2” SAE washer on a 1/2” x 2” bolt followed by a 9/16” high nut and 1/2” serrated edge lock washer.
Thread this tool assembly into the rivet nut as shown. Figure 1

Rivet Nut Installation
5. Place the installation tool with the rivet nut threaded on the end into the appropriately sized hole.
6. For a 3/8” rivet nut, hold the nut closest to the rivet nut still with an 5/8” wrench and tighten the 3/8” bolt with a 9/16 wrench to set the rivet nut. Be sure to hold the rivet nut flush to the surface and square to the hole as it is tightened. Figure 2
Note: If available, an impact gun is recommended for tightening the bolt to ensure the rivet nut remains square to the hole and to ease holding the nut from spinning.
7. For a 1/2” rivet nut, hold the nut closest to the rivet nut still with an 7/8” wrench and tighten the 1/2” bolt with a 3/4” wrench to set the rivet nut. Be sure to hold the rivet nut flush to the surface and square to the hole as it is tightened. Figure 2

Torque Specifications
8. 3/8” rivet nuts will approach 40 ft. lbs for maximum grip strength. Do not exceed 45 ft-lbs when setting the rivet nut.
9. 1/2” rivet nuts will approach 90 ft lbs for maximum grip strength. Do not exceed 100 ft-lbs when setting the rivet nut.
Note: If using the recommended inpact gun, use caution to not exceed the recommended torque specifications.
Rivet Nut Tool Removal
10. Once the center bolt is tightened, remain holding the nut from spinning with the wrench and loosen the center bolt to remove the installation tool.
*IMPORTANT* It is very important to hold the nut as the bolt is loosened because the grip of the star washer will try to spin the rivet nut and ruin the installation.
11. Verify proper installation by checking for consistent rivet nut deformation to see the threads are square and centered to the rivet nut.
