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.

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.

HOLE PREPARATION
2.
Drill hole to appropriate size for rivet nut installation. 1/2” Rivnuts require an 11/16” hole and 3/8” Rivnuts require a 17/32” drill. 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.
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. (Fig. 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. (Fig 1)
FIGURE 1- 1/2” RIVET NUT SHOWN

16 | 012610
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. (Fig. 2)
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. (Fig. 2)
FIGURE 2 - 1/2” RIVET NUT SHOWN
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 impact 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.
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.
