Supertech BMW S63 V8 Conical Spring Kit - Rate 83lbs (Ex) 80lbs (In)

This is the Supertech conical spring kit for the BMW S63 V8 engine. These springs are designed to handle the demands of high-performance engine builds, offering improved valve control at higher RPMs. The conical shape allows for a lighter spring overall while maintaining the necessary seat and open pressures for reliable operation under stress. This kit includes the necessary valve springs to replace the stock units in your S63 V8.

Supertech uses well-built materials and advanced manufacturing processes to create these springs. The exhaust springs have a rate of 83 pounds per inch, and the intake springs are rated at 80 pounds per inch. This specific spring rate is chosen to work effectively with aggressive camshaft profiles and increased boost pressures often found in modified S63 engines. The conical design also helps to reduce valve float and ensures the valves close consistently, which is crucial for maintaining engine power and preventing damage at high engine speeds. Proper valve spring selection is key to unlocking the full potential of a performance engine build.

When installing this kit, it's important to follow the manufacturer's recommended procedures. This typically involves careful disassembly of the cylinder head and proper installation of the new springs and any associated components. Ensure you have the correct tools and knowledge for working on the valvetrain, or consult a professional mechanic. This kit is intended for enthusiasts looking to build a more robust and higher-revving S63 V8 engine.
