What is the main benefit of using dual valve springs?

Dual valve springs, with an inner and outer spring for each valve, are designed to prevent valve float. This occurs when the valve train cannot keep up with the camshaft at high engine speeds, and dual springs provide the necessary force to keep the valves properly seated.

What type of wire is used for these springs?

These springs are made from high-tensile wire. This material is chosen for its ability to withstand the significant stress and heat generated within the engine's cylinder head during operation.

Are retainers and locks included in this kit?

This kit specifically includes the dual valve springs. Retainers, locks, and other associated valve train components are typically sold separately and should be confirmed based on your specific engine build requirements.

Product Details

Supertech is well-known for making performance engine components, and this dual valve spring kit for various BMW engines is a prime example of their focus on precision and reliability. If you're rebuilding the top end of your S42, M42, M50, S50, M52, or M54 engine, this kit is designed to handle the demands of higher lift camshafts and increased RPMs.

This kit includes dual springs, which means you get an inner and outer spring for each valve. This setup is crucial for preventing valve float at high engine speeds. The springs are made from high-tensile wire, a well-built material that can withstand the constant stress and heat inside the cylinder head. Each spring is carefully matched to work together, ensuring consistent valve control and preventing resonance. This attention to detail helps maintain proper valve seating and can contribute to improved engine response and durability under demanding conditions.

When installing this kit, it's important to ensure all components are clean and properly seated according to the manufacturer's specifications. This kit is a significant upgrade for performance builds, allowing your engine to breathe and rev more freely. Always refer to the manufacturer's installation instructions for precise details on assembly and any specific tool requirements.
