Single Valve Springs - 1.437

The Single Valve Springs - 1.437 from Howards Racing Components is designed for automotive enthusiasts looking to enhance their engine's performance. These springs are particularly beneficial for those who require reliable valve control at elevated RPM ranges, making them ideal for street and mild performance builds.

Constructed from high-tensile coil wire, these precision-engineered springs provide the necessary fatigue resistance and load consistency for extended engine operation. The 1.437-inch outer diameter is crucial for ensuring a proper fit within the cylinder head's existing spring pocket, while the correct spring rate is essential for preventing valve float and maintaining optimal valve timing.

Engine builders and mechanics will find these springs particularly advantageous when upgrading or refreshing a complete valvetrain assembly. Proper selection based on camshaft specifications and intended RPM limits will maximize engine longevity and performance.
