The Fox 2.5 Aluminum Shock Reservoir Clamp Kit (803-02-089-KIT) is a pair of extruded aluminum clamp halves, a top and a bottom, that hold a 2.5" remote reservoir shock body to Fox's reservoir mounting hardware. Fox's own install sheets list the top and bottom halves as separate part numbers (026-01-167-1 and 026-01-167-2) for its 2.5 reservoir coilovers. The kit packages both halves with fasteners so you can secure a reservoir without sourcing hardware separately. Compared with generic hose-clamp setups, the machined aluminum halves give the reservoir a fixed, repeatable seat, which matters on off-road builds where a loose reservoir can rattle against the frame or tire. Owners on user forums commonly describe the reservoir position as the main variable, so the clamp is only one part of a sound mount. Expect to plan the reservoir hose routing before you tighten anything. Owners on user forums of 2.5 remote-reservoir coilovers report that hose length and clearance around the sway bar links and coil springs can limit where the reservoir sits, and some rotate the reservoir toward the frame or mount it higher to gain room. Fox's install sheets advise loosely pre-assembling the clamp nearest the front of the vehicle, then tightening once the reservoir is positioned, and pointing the reservoir outward from the shock body. Fitment for the clamp depends on the mounting bracket you use, so verify your bracket type and vehicle application before ordering.

No. This kit is designed for a 2.5" diameter reservoir. Fox identifies the top and bottom halves as 2.5 reservoir clamps, so confirm your reservoir diameter before ordering.
Owners on user forums report that hose length and clearance around sway bar links and coil springs often determine placement. Many find that rotating the reservoir toward the frame or mounting it slightly higher gives the hose more room. Check hose routing through full suspension travel before final tightening.
Installation is a moderate DIY job that comes down to positioning rather than difficult fasteners. Fox's install guidance recommends loosely assembling the clamp closest to the front of the vehicle first, then tightening it after the reservoir is set. Keep the reservoir oriented outward from the shock body and check that the hose clears the spring, sway bar links, and frame at full articulation before torquing. Owners on user forums say the most common problem is hose length, so measure the reservoir position and hose path with the suspension at full droop and full compression before drilling or final tightening. Fox's install sheets vary by application, so follow the guide supplied for your specific bracket and vehicle.
