Description

Kit includes all 12 retainers and all 12 dual valve springs

Retainers:

CNC machined retainers from high strength and hardened aerospace certified titanium alloy. Designed to add strength while offering weight reduction, all of the titanium retainers are finished to precise tolerances

Valve springs:

Computer designed
Extreme wire stress levels
Optimized harmonics
Superior materials

"Our valve springs are computer-designed for long durability under extreme conditions.

There is more to the design and manufacturing of valve springs than achieving pressure and lift. Superior design makes a big difference in valve spring operation and your confidence that they will perform under any condition.

Our valve springs are designed to ensure that wire stress levels do not surpass the limits of stress defined in the diagrams of fatigue.
We use superior materials to manufacture valve springs. For most of our applications, we use wire made from Superclean Chrome Silicon Vanadium alloy. Vanadium increases the tensile strength and improves the life of the spring. High-stress spring applications often call for Chrome Silicon Vanadium Molybdenum+Ni to reach a higher tensile strength and achieve more durability during application.
We measure the natural harmonics of the springs to make sure they are away from the normal engine operation, and we confirm the inner and outer springs counter each other for good control of the valve train operation.
We include a gas nitriding process before shot peening that helps improve the fatigue life of the spring." - SUPERTECH
