Fox Factory Race Series 2.5 x 2.0 Internal Bypass Bump Stop, Eye-to-Eye Mount (981-25-048)

The Fox Factory Race Series 2.5 x 2.0 Bump Stop (981-25-048) utilizes patented internal bypass technology to deliver progressive damping, effectively managing the final inches of suspension travel to provide a near-endless feel. Designed for high-speed off-road environments, this eye-to-eye mounting bump stop allows oil to flow around the piston during the initial stroke before building significant pressure at the bottom-out point for maximum vehicle support.

Built with a 2.5-inch aluminum body and a massive 7/8-inch hard chrome-plated 4130 chromoly steel shaft, this unit is engineered for brute strength and redundant sealing in harsh conditions. The proprietary Cerakote protective ceramic coating over a zinc-plated basecoat offers extreme corrosion resistance, while the JM92 MIL-SPEC oil ensures consistent damping performance during intense racing use.
