Internal Bypass technology allows both compression and rebound damping to be controlled based on the position of the suspension. A hydraulic bump zone is activated in the last few inches of suspension travel.

Position-sensitive damping allows for an initial plush ride and progressively increases in firmness through the damper's stroke.

Internal Floating Pistons (IFP) in each aluminum damper work to help assure maximum damping and sustained fade-free performance.

2.5-inch diameter aluminum bodies lower overall suspension weight and increases the shock fluid capacity for greater cavitation resistance.

Larger inner piston valving circumference allows for better tuning resolution, and custom valving, shock fluid, and nitrogen gas pressure improve bump compliance and help maximize seal life.

Hardened, oversized shock shafts are protected by redundant dust boots.

Utilizes all OE chassis fasteners, mounting points, and bushings for added durability.
