Supertech BMW B58 Beehive Valve Spring Kit (Set Pressure 84 at 37mm)

Supertech is known for making well-built valvetrain components for performance applications. This specific kit is for the BMW B58 engine, featuring beehive-style valve springs designed to handle increased engine speeds and valve lift.

These springs have a set pressure of 84 pounds at 37 millimeters installed height. The beehive shape allows for lighter retainers and reduced mass at the valve tip, which helps improve valvetrain stability at higher RPMs. This can lead to more consistent valve control and better overall engine performance, especially when you're pushing the engine harder. The kit includes all the necessary springs for a complete engine build.

When rebuilding or modifying the top end of your B58 engine, using a matched set of valve springs like these from Supertech ensures proper valve seating and prevents valve float. Always refer to the manufacturer's installation instructions for correct spring height and any specific tool requirements.
