The Kelford KVS401 is a high-performance single valve spring designed specifically for use with OEM retainers in the Ford 105E-116E and Formula Ford applications. These valve springs are engineered to provide optimal performance under demanding conditions.
Constructed from high-quality materials, the KVS401 valve springs are built to withstand the rigors of competitive racing while maintaining reliability and performance. The precise seat pressure ensures that the valves remain securely seated under high RPM conditions, reducing the risk of valve float and enhancing engine efficiency.
For optimal performance, it is recommended to pair the KVS401 valve springs with compatible retainers. Ensure that the installed height is set to achieve the specified seat pressure, and verify clearance to avoid coil bind during operation. Proper installation is crucial for maximizing the benefits of these valve springs.
