These seals offer 700% more bending strength and are 85% harder than other after market competitors . We offer Classic apex seals in 13B and 20B versions and with OR without apex seals springs.
One of the main reasons for developing this product is to correct a problem seen in other seals - the tendency for them to develop chipped corners, especially under severe conditions such as detonation in turbo applications. Even though these new seals are harder, they are much less brittle than previously developed products.
