Supertech Ford RS 2.5L / Volvo 5cyl 80lbs/33.5mm Beehive Single Valve Spring Kit

Supertech is well-known for making solid engine components, and this valve spring kit is a prime example of their work. This kit is specifically designed for Ford RS 2.5L and Volvo 5-cylinder engines, giving you a direct replacement for your stock springs. If you're rebuilding the top end of one of these popular engines, especially if you're looking to handle more aggressive camshafts or higher RPMs, a well-built valve spring is crucial for keeping everything in sync.

This kit features beehive-style single valve springs, which are lighter than traditional dual springs. This weight reduction helps reduce stress on the valvetrain and allows the engine to rev more freely. Each spring is rated for 80 pounds of seat pressure and has a 33.5mm installed height, ensuring it works correctly with your cylinder head and camshaft setup. The beehive shape also helps to reduce spring surge at higher RPMs, contributing to more stable valve control. Supertech uses strong materials and precise manufacturing to ensure these springs can handle the demands of performance applications.

When you're working on these engines, especially for performance builds, ensuring your valvetrain is up to the task is key. This kit includes the single valve springs you need to get the job done. Always refer to your engine's specific service manual for installation procedures and recommended spring seat pressures for your particular camshaft and application.
