Valve Spring Retainers
Supertech retainers are CNC machined from high strength, hardened, aerospace certified titanium alloy. Designed to add strength while offering significant weight reduction over steel, all of our titanium retainers are finished to precise tolerances.
For certain applications we also offer retainers in high strength and hardness aluminum alloy as well as chromoly steel, giving builders the right balance of weight, strength, and cost for their combination.
Key Features
- CNC machined from aerospace certified titanium alloy
- Significant weight reduction over stock steel retainers
- Hardened for durability under high spring pressures
- Aluminum alloy and chromoly steel options on select applications
- Precise tolerances for consistent installed height
- Matched to Supertech springs, keepers, and valve grooves
Applications
For any high-RPM build where valvetrain mass matters. Always pair the retainer with the correct keeper angle and valve groove configuration for your application.
