Comp Cams Valve Spring & Retainer Kit GM LS - Dual Spring 26925CS-KIT

If you're building or refreshing an LS engine, valve spring performance directly impacts your engine's ability to safely sustain high RPM loads and cam aggression. The Comp Cams 26925CS-KIT delivers a proven dual-spring design with the right spring rate and bind characteristics to prevent float while maintaining reliability under sustained boost or naturally aspirated power. This is a critical foundation piece for any serious LS platform engine.

The dual-spring configuration provides superior stability compared to single-spring designs, resisting harmonic resonance and valve float at elevated engine speeds. The Viton seal and steel seat construction ensure longevity and consistent performance across extended duty cycles, whether you're tracking your engine or running consistent street/strip duty.
