Factory-Fit Fox Performance for the Grenadier — Without Compromising OEM Reliability
The Fox 2.5 Performance Elite Series shocks are a bolt-on solution tuned specifically for the 2022+ INEOS Grenadier. The 2.5-inch aluminum bodies with external reservoirs increase oil capacity, allow additional shock stroke to maintain available travel, and eliminate the harshness associated with nitrogen ramp-up under compression. The result is a shock that performs meaningfully better than OEM on rough terrain while remaining comfortable and predictable on road.
The DSC EVO (Dual Speed Compression Evolution) adjuster features Variable Valve Control (VVC) on the high-speed circuit — a design that adds high-speed compression damping without adding preload to the shim stack. Independent high and low-speed circuits mean you can add clicks of high-speed compression to handle big hits without sacrificing small-bump sensitivity. The adjuster is strategically positioned to eliminate interference with aggressive tires at full lock. Available as front only, rear only, or the complete front + rear set.
Configuration Options
-
Front + Rear Set — complete upgrade for both axles (2 front + 2 rear shocks)
-
Front Only — front axle upgrade (2 shocks, part 883-26-166)
-
Rear Only — rear axle upgrade (2 shocks, part 883-26-273)

FAQ
How many shocks are included per option?
Front Only and Rear Only options each include 2 shocks (one per side for that axle). The Front + Rear Set includes all 4 shocks for a complete vehicle upgrade.
Will this affect my Grenadier's factory warranty?
Fox shocks are a direct bolt-on replacement using factory mounting points. As with any aftermarket part, consult your dealer — but the installation itself does not require permanent modification.
What does DSC EVO actually change vs standard shocks?
DSC EVO gives you independent control over high-speed and low-speed compression damping. On trail, this means you can run more high-speed compression for big hits while keeping low-speed soft for small bumps and body roll. Standard adjusters typically compromise one circuit to improve the other.
Is this a significant upgrade over OEM?
Yes — the external reservoir alone adds meaningful capacity and stroke over the factory units. Combined with DSC EVO tuning, the Grenadier rides noticeably better on rough terrain while remaining composed on road. Fox specifically tuned this application for the Grenadier's character.
