Supertech BMW S65/S85 Beehive Valve Spring - Set of 40 (Use w/Factory Retainer & Base)

This is a set of 40 Supertech Beehive valve springs designed specifically for BMW S65 and S85 engines. These springs are intended to be used with your factory retainers and bases, making them a direct replacement for your original valve springs. If you're rebuilding the top end of your S65 or S85, or looking to upgrade to a more robust setup, these springs are a solid choice.

Supertech uses a beehive design for these springs, which is notable for its ability to reduce mass compared to traditional dual-wound springs. This lighter weight allows the engine to rev more freely and can help prevent valve float at higher RPMs. The springs are made from high-strength materials to handle the demands of these high-performance V8 engines. They are designed to maintain consistent pressure across their lifespan, ensuring reliable valve operation.

This set includes 40 individual springs, enough for a complete engine installation. When installing, ensure you follow the manufacturer's recommended procedures for valve spring replacement. Using the factory retainers and bases means you're working with components already proven to fit your engine, simplifying the installation process. This upgrade is a key component for anyone looking to ensure the longevity and performance of their S65 or S85 engine.
