MTS Off-Road High Volume Reservoir Caps (for Walker Evans Shocks)
Upgrade your shock service routine with MTS Off-Road Schrader Valve Reservoir Caps for Walker Evans shocks — easy nitrogen access, leak prevention, and up to 300 PSI capability. Not compatible with Fox reservoirs.
The MTS Off-Road Schrader Valve Reservoir Caps (For Walker Evans Shocks) are precision shock reservoir accessory components designed to replace stock caps on Walker Evans shock reservoirs with diameters from 2.0″ to 2.5″. These caps include integrated Schrader valves for simpler and faster nitrogen pressure checks and fills compared to traditional pellet caps. They allow you to maintain proper nitrogen pressures — up to 300 PSI, which can help reduce cavitation and improve shock performance over stock caps that typically limit nitrogen to ~200 PSI.
⚠️ Important: These reservoir caps do not work with Fox shock reservoirs — they’re specifically for Walker Evans setups.
Key Features:
-
Includes Complete Set of 4 Caps: Four reservoir caps sized for your chosen configuration (e.g., all 2.5″ or mix of 2.0″ & 2.5″).
-
Schrader Valve Access: Built-in Schrader valves make checking and adding nitrogen quick and easy.
-
Higher PSI Capability: Supports up to 300 PSI nitrogen fill — more than many OEM pellet caps.
-
Leak Prevention: Replaces stock reservoir caps to eliminate leaks and provide sealed access under pressure.
-
Walker Evans Compatibility: Made specifically for Walker Evans shock reservoirs sized 2.0″ – 2.5″.
-
Not Compatible with Fox: Won’t work for Fox reservoir systems — separate Fox-specific caps exist.
Fitment:
Designed specifically for Walker Evans shock reservoirs with 2.0″ to 2.5″ bore. Typical applications include many Polaris RZR, Can-Am Maverick X3, and other UTVs equipped with Walker Evans remote reservoirs. Always confirm reservoir diameter and shock brand before purchase.
