Supertech Ford Coyote Beehive Valve Spring OD .989in/.693in - 91lbs / 1.575in - Single

These Supertech beehive valve springs are built for Ford Coyote engines. The unique beehive shape allows for a smaller retainer, which reduces mass up top and helps the engine rev more freely. This particular spring offers 91 pounds of seat pressure at 1.575 inches installed height, and 196 pounds of open pressure at 1.150 inches. This makes them a solid option for stock to mildly modified Coyote engines looking for improved valve control without excessive spring pressure.

The springs are made from high-strength spring steel, ensuring they can handle the demands of the Coyote's valvetrain. They are designed as a direct replacement for the factory springs, making installation straightforward for those rebuilding or upgrading their engine's top end. Proper installation involves ensuring the valve guides are in good condition and the spring seats are clean and flat.
