FOX Race Series 2.5 x 2.0 Bump Stop Eye-Eye Mount
The FOX Race Series 2.5 x 2.0 Bump Stop Eye-Eye Mount delivers patented internal bypass technology for smooth oil flow early in the stroke and building pressure at full compression to maintain tire contact. Built for off-road race trucks, UTVs and custom suspensions, it absorbs hard landings with a 2.5-inch aluminum body, 7/8-inch shaft and redundant seals proven in desert racing and short course. This eye-to-eye component fits universal race setups requiring precise bump control.
