Valve Spring - HDEP EPA07/EPA10/GHG17
Detroit Diesel

This high-performance valve spring is essential for ensuring stable valve operation under high loads and RPMs typical in heavy-duty engines. With a free length of approximately 99.40 mm and a wire diameter of 4.85 mm, it provides robust tension to keep valves sealed tightly against their seats. The inner diameter of 19.30 mm and outer diameter of 29 mm are designed for compatibility with specific valve guides and retainers, promoting smooth valve motion. The compressed length of around 60.90 mm allows for effective clearance once installed, ensuring reliable valve closure. Manufactured from high-grade steel, it offers excellent fatigue resistance and thermal stability, critical for demanding engine cycles. Regular inspection of valve springs like this one is vital to prevent valve float, misfires, or engine damage.
