Valve Springs - Triple 1.686in

The Valve Springs - Triple 1.686in from COMP CAMS is a high-performance triple-spring assembly engineered for serious engine builders and racing enthusiasts who demand reliable valve control at extreme RPM levels. This set of 16 valve springs is designed for elite race applications where precision valve seating and consistent lift response are non-negotiable. Triple-spring configurations provide superior stability compared to dual-spring designs, eliminating valve float and maintaining accurate valve timing under aggressive cam profiles.

Each Valve Springs - Triple 1.686in features a 712 lb/in spring rate with a 1.161 inch coil bind specification, delivering the stiffness necessary to control modern high-lift camshaft designs without premature failure. The 1.686 inch outer diameter is a standard competition size that fits most small-block and big-block cylinder heads with ported or stock configurations. COMP CAMS' precise manufacturing tolerances ensure consistent spring pressure across all 16 units, critical for balanced engine performance and preventing weak valves that can cause compression loss or bent pushrods.

Professional engine builders, bracket racers, and weekend track competitors rely on these triple valve springs when installing performance camshafts that exceed factory spring capabilities. Installation requires removing the cylinder head and using a valve spring compressor tool—a task best performed by experienced technicians or qualified machine shops. Compatibility spans multiple Chevy, Ford, and Mopar platforms with aftermarket or race-prepped heads. For builders seeking maximum valve control with minimal risk of float or breakage, this COMP CAMS set delivers race-proven reliability at competition-grade specifications.
