Front 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.
