Spring Valve - Heavy Duty EPA07/EPA10/GHG17
Detroit Diesel

This steel valve spring for HDEP engines maintains critical tension on the valve during high-speed operation, ensuring proper sealing of the combustion chamber. Its 99.90 mm free length and 4.50 mm wire diameter are tailored to withstand the intense cyclical forces in EPA07/EPA10 and GHG17 applications. The spring's resilience prevents valve float and misalignment, which could lead to performance drops or engine damage. Its robustness under thermal and mechanical stress makes it a vital component in maintaining consistent valve timing, emission standards, and fuel economy. Ensuring the integrity of this spring through quality parts from Source One Parts Center helps preserve engine longevity and operational reliability.
