Description

Manley Budget series replacement valves are high-quality valves at very affordable prices. All valves are made from stainless steel (intakes are NK-840; exhausts are XH-422) with chrome stems and hardened valve tips. They are original equipment shapes with forged and machined finishes. Both the materials used and the heat-treating processes are superior to those of the original equipment replacement pieces.
