The CB Performance VW650 Dual Valve Springs are engineered for high-performance engines, designed to rev up to 8500 RPM. These top-tier dual springs are a drop-in upgrade for heads machined to fit VW diameter dual springs.

Crafted from NASCAR-grade proprietary material, they offer unsurpassed high-cycle fatigue life, ensuring extreme endurance and reliable valve control while minimizing valve float. The springs undergo extensive surface finishing, including nitriding, polishing, heat set, and micro shot peening, making them ideal for both street and strip applications.

NOTE: For optimal performance, pair with CB Performance Titanium Retainers and Chromoly Super Duty Pushrods. Always verify spring clearance to prevent coil bind, especially with high-lift cams (e.g., Eagle 2289/2298 with 1.4 rockers). Professional installation and precise measurements are recommended to ensure safe operation.
