Dual Valve Springs - 1.540

The HOWARDS RACING COMPONENTS Dual Valve Springs – 1.540 OD are designed for engine builders and performance enthusiasts who require reliability under high-stress conditions. These dual valve springs are a crucial upgrade for applications where stock springs fail to provide adequate load and control, making them suitable for street performance engines, competition packages, and cylinder head rebuilds.

Constructed from precision-wound steel, these dual valve springs feature a 1.540-inch outer diameter and are engineered to maintain consistent load curves and extended service life. The dual configuration allows for higher spring rates and improved harmonics compared to single springs, reducing the risk of coil bind and enhancing damping characteristics to maintain valve timing across the RPM range.

Ideal for high-performance engine builds, these valve springs are particularly beneficial for applications targeting stability at high RPMs. They are compatible with classic small-block engines commonly found in street rods, muscle cars, and vintage racing platforms, ensuring that valves remain seated and preventing float during operation.
