Valves
Your engine breathes, adjusts timing, and manages fluid flow through a network of valves—and every one of them must open and close with absolute precision. This collection brings together the valves you need to build, rebuild, or upgrade your vehicle's most critical systems.
We carry intake and exhaust valves in stock and oversized diameters, from stainless steel to titanium and sodium-filled options, along with valvetrain components like valve guides, seals, and keepers. You'll also find PCV valves, wastegate valves, blow-off valves, check valves, and fuel system valves—all from manufacturers who understand the heat, pressure, and fatigue cycles these parts endure.
How to choose:
- Match the valve to your cylinder head's seat dimensions and stem diameter—always verify against your engine builder's specs or OE measurements.
- For forced induction or high-rpm builds, consider upgraded materials and multi-angle valve jobs to improve flow and heat dissipation.
- When replacing a failed valve, inspect the guide, seat, and related components; a dropped valve is often a symptom, not the root cause.
- System-specific valves (PCV, wastegate, etc.) should match the intended boost, vacuum, or pressure levels exactly; a wrong spring rate or seal material can cause drivability issues or even engine damage.
Whether you're lapping in a single replacement or assembling a full valvetrain for a race motor, we have the precision components to keep everything sealing and flowing as designed.
