COMP Cams Valve Springs Nascar

These COMP Cams NASCAR Dual Valve Springs, part number 927-12, are built for demanding engine builds where reliability under extreme conditions is key. They feature a 1.551 inch outside diameter and are designed to be installed at a height of 1.950 inches. This dual spring setup offers improved stability for your valve train, especially when dealing with aggressive camshaft profiles and high RPMs. The NASCAR designation suggests these springs are engineered to withstand the kind of stress found in competitive racing environments, meaning they're well-built for any high-performance street or track application.

When you're building a serious engine, the valve springs are a critical component that often gets overlooked. They need to be strong enough to close the valves quickly and consistently, even with significant valve lift, while also resisting fatigue over thousands of cycles. These COMP Cams springs are designed to handle that pressure. The dual spring design provides redundancy and better dampening characteristics compared to single springs, helping to prevent valve float at high engine speeds. This means you can push your engine harder, knowing the valve train is better supported.

This kit includes 12 springs, which is standard for most V8 engine configurations. While these are designed for high-performance use, it's always a good idea to consult your camshaft manufacturer's specifications to ensure these springs are the correct match for your specific lift and seat pressure requirements. Proper installation is crucial for valve spring longevity and engine health, so refer to COMP Cams' installation guidelines for best practices.
