The HydraStrike Disogrin seals are used to deliver exceptional sealing performance and long-term wear resistance in harsh off-road environments. These oversized industry leading seals provide a larger contact surface that better resists contamination, reduces leakage, and maintains consistent damping performance over time. Providing a hydraulic bump that stays smooth, reliable, and serviceable even after repeated harsh impacts.
The massive 5/8” wide Polytetrafluoroethylene (PTFE) lined shaft bearing is built into the HydraStrike to better distribute side loads and reduce friction under compression. This wider bearing improves stability during angled or high-speed impacts, minimizing shaft deflection and premature wear. The PTFE lining ensures smooth operation without binding, all while extending the service life in demanding off-road conditions.
The HydraStrike body threads allow direct compatibility with existing Fox weld-in mounts allowing upgrading simple for users already running Fox hardware, eliminating the need for cutting, re-welding, or replacing mounts. It provides a true bolt-in performance upgrade path that saves time and money.
Each HydraStrike includes a molded rubber strike pad with an integrated steel core to refine impact feel and reduce noise at full compression. This design softens harsh bottom outs while maintaining durability, making it ideal for daily drivers and trail rigs. The steel core ensures long-term strength without sacrificing performance.
HydraStrike is built around a .125” wall tube shaft, providing a substantial strength advantage over the thinner .085” wall designs. This thicker shaft improves resistance to bending and deformation under extreme loads, increasing durability during hard impacts and aggressive driving. Giving you the confidence to push your suspension to its limits.

THE TECH
Front HydraStrike Hydraulic Nitrogen Charged Bump Stops
Incredible Strength
HydraStrike is built around a .125” wall tube shaft, providing a substantial strength advantage over the thinner .085” wall designs. This thicker shaft improves resistance to bending and deformation under extreme loads, increasing durability during hard impacts and aggressive driving. Giving you the confidence to push your suspension to its limits.
Industry Leading Disogrin Seals
The HydraStrike Disogrin seals are used to deliver exceptional sealing performance and long-term wear resistance in harsh off-road environments. These oversized industry leading seals provide a larger contact surface that better resists contamination, reduces leakage, and maintains consistent damping performance over time. Providing a hydraulic bump that stays smooth, reliable, and serviceable even after repeated harsh impacts.
PTFE Lined Shaft Bearing
The massive 5/8” wide Polytetrafluoroethylene (PTFE) lined shaft bearing is built into the HydraStrike to better distribute side loads and reduce friction under compression. This wider bearing improves stability during angled or high-speed impacts, minimizing shaft deflection and premature wear. The PTFE lining ensures smooth operation without binding, all while extending the service life in demanding off-road conditions.
Internal Reservoir
The HydraStrike’s internal reservoir is engineered to maintain a precise nitrogen charge while keeping it completely separated from the shock oil. This separation eliminates foaming, stabilizes pressure, and ensures damping remains consistent no matter how hard the suspension is pushed. It’s a design focused on durability, consistency, and uncompromising off-road performance.
Molded Rubber Strike Pad
Each HydraStrike includes a molded rubber strike pad with an integrated steel core to refine impact feel and reduce noise at full compression. This design softens harsh bottom outs while maintaining durability, making it ideal for daily drivers and trail rigs. The steel core ensures long-term strength without sacrificing performance.
