The BDS NX2 series gas shocks offer impressive performance on and off-road. Standard in most BDS lift kits, these nitrogen-charged, twin-tube shocks offer 10-stage velocity-sensitive valving for lightning-fast damper performance and control.

Note:

This kit only fits vehicles equipped with a short arm lift system. This kit requires shocks in the stock location or appropriate limiting straps to avoid hanging the front axle from the dual shock cylinders. If the correct stock location shocks are not installed or limiting straps are not used.

Improve ride quality and capability with the FOX 2.0 performance series IFP shocks. Specially designed for BDS lift systems, these FOX 2.0 aluminum body shocks offer improved cooling capacity and corrosion protection. These shocks use race-proven vehicle-specific valving along with an internal floating piston (IFP) monotube design to separate the shock oil from high-pressure nitrogen to eliminate aeration and maximize performance on/off-road.

Note:

• This kit is designed to work with vehicles that have the BDS long arm system installed.
• This kit requires shocks in the stock location or appropriate limiting straps to avoid hanging the front axle from the dual shock cylinders.
• If the correct stock location shocks are not installed or limiting straps are not used, order 2 stock location shocks and 4 bracket location shocks with this system.

Steering Dampers may differ from the installation image.

Note:

• This is an end-to-end style dual stabilizer.
• This system will work on stock height vehicles.

BDS Suspension's revolutionary spring-loaded, full-floating RECOIL traction bar system is engineered to improve traction and limit axle wrap without limiting suspension travel or decreasing ride quality. These traction bars offer you the freedom to tune the spring tension for optimal performance on-road, off-road, towing, or competition pulling. These traction bars can be used on stock height or lifted trucks and work with both lift blocks and replacement leaf spring kits.

Reduce rear pinion angle change commonly referred to as axle wrap during acceleration with these BDS heavy-duty traction bars. Tubular design for good looks as well as serious axle control.

 Bracket kits are vehicle specific. The frame brackets install by drilling mounting holes for the brackets while the axle brackets install using a set of u-bolts. The traction bars and mounting brackets use a durable gloss black powder coat finish.

Note:

• Choose this option if your driveshaft has 3" or more clearance to the crossmember and you have an automatic transmission. See installation instructions for measurement details.
• 03-12 2500 Gas models will require modification to the front exhaust crossover pipe on driver's side for proper clearance

Note:

• Choose this option if your driveshaft has 3" or more clearance to the crossmember and you have a manual transmission. See installation instructions for measurement details.

Choose this option if your driveshaft has less than 3" of clearance to the crossmember and your truck has the factory transmission mount p/n 52121938AA. See installation instructions for measurement details.

Note:

If your driveshaft has less than 3" of clearance to the crossmember and you do not have the provided transmission mount part number then contact BDS Tech Support.
