Read and understand all instructions and warnings prior
to installation of system and operation of vehicle.
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.
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
Pre-Installation Notes
1. Special literature required: OE Service Manual for model/year of vehicle. Refer to manual for proper disassembly/
reassembly procedures of OE and related components.
2. Adhere to recommendations when replacement fasteners, retainers and keepers are called out in the OE manual.
3. 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
4. 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.
5. Secure and properly block vehicle prior to installation of BDS Suspension components. Always wear safety glasses
when using power tools.
6. If installation is to be performed without a hoist, BDS Suspension Co. recommends rear alterations first.
7. 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
1. 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.
2. 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.
3. Perform head light check and adjustment.
4. Re-torque all fasteners after 500 miles. Always inspect fasteners and components during routine servicing.
