Construction & Design

This valve spring is manufactured from high-quality corrosion-resistant steel, providing excellent resistance to wear, fatigue, and heat. The innovative single beehive shape reduces the overall mass of the spring, which improves valve train dynamics by minimizing inertia and enhancing response times. This design also facilitates better heat dissipation and reduces the risk of coil clash during high RPM operation, making it suitable for both street and competitive racing environments.

Each spring is precision engineered to exact tolerances, ensuring it perfectly matches the valve train geometry of the 5.7L Hemi engine. This guarantees reliable performance whether used in stock rebuilds or high-performance engine builds.
