Fox 2.0 Series Shocks (2x)
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.

These new track bars are a massive upgrade to the factory unit, constructed from 1-3/8 solid steel stock reinforced with gusseted ends to handle whatever on-road and off-road abuse you can through at it. Adjustments are made at the 1-3/8-12 fine threaded center turnbuckle with pinch bolt ends to allow easy tuning to properly recenter the front axle for a range of lift heights. The track bar is formed for proper clearance around critical front-end components and is designed to easy installation without the need to clear the factory frame and axle mounts. Both ends use high-durometer polyurethane bushings with thick-walled steel sleeves for strength and reliability. Parts come with a high-quality textured black powder coat finish for a great look and excellent corrosion resistance. They are designed for use on 0-3" of lift and can be used in combination with most aftermarket track bar brackets to be used on taller lift heights.
