Outer Valve Springs With Damper- 1.354 Dia.

The COMP CAMS Outer Valve Springs With Damper (Part 910-16) is a performance-grade valve spring assembly designed for high-RPM engine builds and racing applications. Each set contains 16 outer valve springs with integrated dampers, engineered to manage valve train harmonics and prevent spring surge at elevated engine speeds. The 1.354-inch outer diameter and 458 lb/in spring rate make this component suitable for naturally aspirated and moderately boosted engines requiring robust valve control.

With a 1.280-inch coil bind specification, these springs offer a working range optimized for street and competition use without excessive preload. The damper component absorbs oscillations within the valve train, reducing noise and extending component lifespan under demanding conditions. COMP CAMS valve springs are manufactured to strict tolerances and undergo rigorous testing to ensure consistent performance across the entire set. The verified specifications—458 lb/in rate and 1.354 in OD—are critical for compatibility with existing valve hardware and cylinder head geometry; buyers must confirm fitment with their engine specifications before installation.

This valve spring set is intended for engine builders, performance shops, and enthusiasts undertaking cam upgrades, head porting, or increased-lift valvetrain modifications. Proper installation requires correct valve spring installed height measurement and compatible retainers and keepers. The outer spring is typically paired with an inner spring in a dual-spring arrangement common in performance engines, providing the outer damping layer while the inner spring carries primary load.

COMP CAMS is recognized for precision valve train components across street, strip, and road racing segments. Selecting the correct spring rate and outer diameter ensures the valve train closes reliably under boost, high RPM, and sustained acceleration without coil bind or float conditions.
