FOX Factory Race Series 3.0 External Bypass Rear Shocks (Pair) – QAB – 2017–2018 Ford Raptor

FOX Factory Race Series 3.0 QAB External Bypass Rear Shocks (Pair)

2017–2018 Ford Raptor (Gen-2)

Inspired by professional off-road racing technology, the FOX Factory Race Series 3.0 External Bypass rear shocks deliver massive gains in ride control, heat management, and suspension performance for Gen-2 Raptors.

These shocks use external bypass tubes to create position-sensitive damping, allowing the suspension to ride smoothly through normal travel while automatically increasing damping force during aggressive compression, hard landings, and high-speed off-road impacts.

FOX Quick Adjust Bypass (QAB) technology allows fast, tool-free tuning of bypass zones so you can quickly dial in compression characteristics for different terrain and driving styles.

Combined with FOX’s External Cooling System (ECS2) and finned remote reservoirs, these shocks maintain consistent damping performance even during extended high-speed desert runs.

Designed as a true bolt-on upgrade, these shocks install directly into factory mounting locations with no fabrication required.
