What is the primary benefit of using dual valve springs?

Dual valve springs offer increased seat and open pressures compared to single springs. This helps prevent valve float at higher engine speeds, allowing for more consistent valvetrain operation and improved performance in modified engines.

What materials are used in the Supertech dual valve spring kit?

The springs are made from high-tensile chrome-silicon wire. This material is chosen for its strength and its ability to maintain consistent tension under repeated stress, which is crucial for high-performance applications.

What components are included in this valve spring kit?

This kit typically includes the dual valve springs themselves, along with the necessary retainers, and any required locators or seats for proper installation. It aims to provide a complete package for your valvetrain upgrade.

If you're rebuilding the top end of your S42, M42, M50, S50, M52, or M54 engine, these springs are a critical component for ensuring your valvetrain operates correctly at higher RPMs and under more aggressive camshaft profiles. They are built to handle the demands of performance builds where stock springs might not be up to the task.

Supertech uses high-tensile chrome-silicon wire for these springs, which is known for its strength and ability to withstand repeated stress without losing its tension. The dual spring design offers increased seat pressure and open pressure compared to single springs, which is essential for preventing valve float at high engine speeds. This improved control over the valves helps maintain consistent performance and can protect your engine from damage caused by uncontrolled valve movement. The kit includes springs, retainers, and any necessary locators or seats, providing a comprehensive solution for your valvetrain upgrade. When installing, pay close attention to the spring pressures specified by Supertech for your application to ensure proper setup and optimal performance.

This kit is a solid option for enthusiasts looking to push their BMW engines further. Proper installation is key to realizing the full benefits of these springs, so ensure you follow the manufacturer's guidelines or consult a trusted mechanic. The materials and design are intended to offer reliable performance for modified engines.
