Regular price $698.50 USD
Regular price Sale price $698.50 USD

The BMW S85 engine is known to have valve springs that often break, even in a stock engine. We recommend replacing the valve springs with these economical and high quality beehive valve springs from Supertech. These are a great compliment to our Stage 1 and Stage 2 cylinder heads.

Supertech Valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high rpms and better memory. Computer designed to ensure that wire stress levels do not overpass the limits of stress defined in the diagrams of fatigue for long durability under extreme conditions. Computer software also allows Supertech to make sure that the harmonics are well under control.

These springs have been thoroughly tested and performed flawlessly with nearly all the cams from Schrick.
