All Supertech valve springs are made of Superclean premium chrome-vanadium steel alloy for higher efficiency and durability at high speed.

The use of high-quality steel alloy provides an additional benefit in the form of better structural memory for all our springs.

Our valve springs are computer-designed to ensure that stress levels do not exceed the stress limits specified in the fatigue graphs.

Combined with our high-quality steel alloy, it gives Supertech valve springs more durability in extreme conditions, giving the racing engine a serious advantage in both performance and durability.

Supertech pushers are manufactured from high quality military-certified titanium alloy and are machined on CNC to provide tight fit.

Our high-quality pushers are among the best in the industry.
