Outer Valve Spring With Damper- 1.440 Dia.

The Outer Valve Spring With Damper - 1.440 Dia. from COMP CAMS is a precision-engineered valve spring assembly designed for serious engine builders and performance enthusiasts seeking reliable, repeatable valve control in high-RPM applications. This set of 16 springs addresses a critical need in modern performance engine development: maintaining consistent valve actuation while managing harmonic instability that can lead to premature spring failure. Whether you're building a competition small-block, stroker motor, or upgrading a street machine, quality outer springs with dampers separate reliable long-term durability from catastrophic mid-season failures.

This outer valve spring delivers a 350 lb/in spring rate with a 1.100-inch coil bind specification and a 1.440-inch outer diameter, making it compatible with most modern small-block and mid-sized engine platforms. The integrated damper works by dissipating resonant energy that builds during rapid valve cycling, reducing harmonically-induced fractures and maintaining stable spring preload across extended engine operation. COMP CAMS' manufacturing precision ensures consistent wire diameter and coil geometry across the full set, critical factors that prevent individual springs from fatiguing at different rates—a common problem with lesser-quality alternatives that leads to uneven cylinder pressure and misfires.

Builders upgrading to higher-lift cam profiles, increasing engine displacement, or pushing RPM limits benefit most from this damper-equipped outer spring design. The set of 16 springs ensures you have enough for complete cylinder coverage on most V-8 configurations, with spares for testing or future builds. Installation requires careful attention to spring seat height, installed load measurement, and proper shimming to achieve the target preload—professional installation or detailed cam manufacturer specifications are strongly recommended to maximize spring life and engine reliability.
