Reduce heat. Minimize friction. Prevent spring failure.
Valve springs operate under constant motion and extreme stress, generating heat through both internal flexing and external contact with surrounding components. This friction and heat leads to fatigue, loss of spring tension, and eventual failure — especially in high-RPM applications.
For complete valvetrain coverage, pair with our valve coatings and cylinder head coatings.
Reduces internal flex friction and external contact wear.
Less friction means lower operating temperatures.
Prevents fatigue-related spring pressure loss.
Extends life in high-RPM and race applications.
Valve springs generate heat from two sources: internal flexing as the spring compresses and rebounds thousands of times per minute, and external friction where coils contact each other and surrounding surfaces. This heat buildup is the primary cause of fatigue and tension loss.
Dry film lubricant coating (DFL-1) creates a slick, low-friction surface that reduces both internal and external friction. This lowers operating temperatures, minimizes wear during continuous cycling, and helps maintain consistent spring pressure throughout the engine's operating range.
Properly applied coatings are extremely thin and do not affect spring rate or installed height — they simply add durability.
They reduce friction and heat buildup caused by constant spring movement, helping improve reliability and longevity.
No. Properly applied coatings are extremely thin and do not interfere with spring rate or operation.
Heat is generated through internal flexing and friction between contacting surfaces during continuous cycling.
No. They benefit any engine where valvetrain durability and consistent performance are important.
Highly recommended. Multiple springs generate more friction and heat, making coatings especially valuable.
Improve durability, reduce wear, and prevent failure with coatings designed for high-stress valve train components.
