Supertech Titanium Retainer BMW S85- Set of 40

If you're working on the high-performance S85 V10 engine found in certain BMW M models, these Supertech Titanium Retainers are a key component for rebuilding or upgrading your valve train. This set includes 40 retainers, enough for all 40 valves in the engine. They are specifically designed to work with Supertech valve springs and are made from high-grade titanium to reduce weight and improve valvetrain stability at high RPMs.

Titanium is significantly lighter than the stock steel retainers, which means less mass moving around in your valvetrain. This reduction in reciprocating mass helps the engine rev more freely and can improve its ability to handle higher engine speeds without valve float. The material itself is also very strong and resistant to heat, making it a solid choice for performance applications where the engine will be pushed hard. Supertech is well-known for producing reliable valvetrain components, and these retainers are a popular choice for S85 builds aiming for improved performance and durability.

When installing these retainers, it's important to ensure you are using them with compatible Supertech valve springs and that all other valvetrain components are in good condition. Proper installation is crucial for the longevity and performance of your engine. This set is designed as a direct replacement for the factory retainers, simplifying the installation process for experienced mechanics and engine builders.
