The Manley BBM R/M 1.810-inch exhaust valves are precision-engineered performance components designed for high-output Mopar RB-series engine applications. This set includes eight stainless steel valves, each featuring a 1.810-inch head diameter and a 0.342-inch valve stem, suitable for both street and competition builds.
Manufactured from premium stainless steel alloy formulations, these valves provide the thermal stability and flow characteristics necessary for sustained high-RPM operation and elevated boost conditions. The design ensures compatibility with OEM valve guides while maintaining the rigidity required for high-lift, high-duration camshaft profiles.
Manley valves are particularly beneficial for builds that experience aggressive power adders or extended wide-open-throttle duty cycles, addressing the common failure modes of OEM RB-series valves under extreme conditions. These valves are a reliable choice for enthusiasts looking to enhance their engine's performance and longevity.
