RA 2mm Classic Apex Seals
Our RA Classic Seals are running in hundreds of race and street cars throughout the world. They are perfect for stock engines and boosted street and track cars.
We offer a choice of Race springs (for high performance engines) and RA Classic springs, for stock engines.
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.
