Információ a termékről

All Supertech valve springs are made of Superclean premium chrome vanadium steel, which ensures higher performance and durability at high revs.
The use of high-quality steel alloy provides the additional advantage 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 charts.
Combined with our high-quality steel alloy, Supertech gives the springs greater resistance under extreme conditions, providing the race engine with a major advantage in terms of both performance and durability.
Supertech cam followers are manufactured from a high quality, military-grade titanium alloy and are machined on a CNC to ensure a tight fit.
Our high quality followers are among the best in the industry.
