Precision Valve Shims for Vanguard Mud Motors | Mud Motor Central
Mud Motor Central Anti-Valve-Float Shims are engineered to increase valve spring seat pressure and prevent valve float in high-RPM mud motor applications. When upgrading to performance cams, stainless valves, ported heads, or higher compression builds, valve float becomes a common issue—causing lost RPM, misfire, and even valve-to-piston contact.
These precision-machined shims install under the valve spring to tighten up the spring’s seat pressure, ensuring the valve stays fully controlled throughout the entire lift cycle. Ideal for Vanguard 25–40 HP EFI builds running big cams, billet components, or extended wide-open-throttle use.
A simple and inexpensive upgrade that dramatically improves high-RPM stability and reliability in performance mud motors.
