Valve Spring Cups- 1.550 x 1.680 OD x .577 ID

The Valve Spring Cups 1.550 x 1.680 OD x .577 ID from HOWARDS RACING COMPONENTS are precision-engineered valve spring locators designed for high-performance engine builds and racing applications. These components serve a critical function in maintaining proper valve spring seating and alignment within the cylinder head, ensuring consistent valve actuation and preventing spring coil bind during aggressive valve lift events. Engine builders and performance enthusiasts rely on quality spring cups to protect their valve train investment and maximize reliability under extreme operating conditions.

Manufactured from steel and finished in black oxide, these valve spring cups feature a 1.680-inch outer diameter with a 0.577-inch inner diameter bore, accommodating valve stems with a 1.550-inch spring diameter specification. The 0.060-inch thickness provides optimal load distribution while maintaining the structural integrity required during high-RPM operation. Black oxide coating offers corrosion resistance and a professional appearance while reducing friction against the valve spring seat. Each set contains 16 cups, supplying a complete small-block engine installation with pairs for all eight cylinders.

These spring cups are ideal for serious engine builders preparing small-block performance engines for street, strip, or competition use. Proper valve spring cup selection is essential when upgrading to higher-lift camshafts or stiffer valve springs, as mismatched components can lead to premature wear or catastrophic valve train failure. Installation requires careful alignment during cylinder head assembly to ensure even pressure distribution across the spring seat. Buyers seeking valve spring cups for sale should verify compatibility with their specific valve spring specifications and cylinder head design before ordering.
