MTS Off-Road High Volume Reservoir Caps (FOR FOX SHOCKS)
*Does NOT Work for Walker Evans Reservoirs*
Includes 4 Reservoir Caps
Made for Fox Reservoirs 2.5" in diameter
Our MTS Reservoir caps allow for easy and regular nitrogen service, and allow you to exceed 200 PSI.
Easy and regular checks: With our easy-to-fill Schrader Valve, your nitrogen can be checked and filled faster and easier than typical pellet caps. Nitrogen should be checked at least twice a season, as shocks typically lose 30 PSI every 6 months. Going below 150 PSI can cause cavitation in your shocks, which can cause unnecessary heat, premature wear, and a decrease in handling.
Higher PSI Capacity - MTS Reservoir caps allow for up to 300 PSI of nitrogen, while OEM pellet cap styles will not allow you to exceed 200 psi, and for larger vehicles and more aggressive drivers, this extra nitrogen will prevent cavitation and added bottom-out resistance.
This definitely fits well and hold firmly, but the value is not what I anticipated. The fasteners are silver and stick out like a sore thumb. The mount between the plate and the clamp seems to made out of PETG 3D printed material, it could have at least been a more sturdy material. The mount should also be printed with a few more layers in height to give a bit more clearance. Although not NEEDED, a sheet with quick instructions would have been nice as well. I would recommend this for a 2026 Pro XP, but it should be about 50% off its current price.
