1.307 Valve Spring - Ovate Beehive (1)

The PAC Racing Springs 1.307 Valve Spring – Ovate Beehive is a high-performance valve spring specifically designed for GM LS-series engine platforms. This single ovate beehive spring is engineered to enhance valve control and stability at high RPMs, making it ideal for racing and performance applications where precision is crucial for engine reliability and power delivery.

Manufactured to OEM-equivalent tolerances, this valve spring utilizes high-quality music wire to ensure consistent performance across a wide operating range. The ovate beehive design minimizes spring surge and harmonics, allowing for higher thresholds of valve float and compatibility with more aggressive cam profiles. The 1.100-inch coil bind specification is a standard feature that prevents coil stacking during maximum lift scenarios.

This valve spring is perfect for LS engine enthusiasts looking to build street performance, track, or competition powerplants. It is particularly beneficial for those using aftermarket camshafts in naturally aspirated or boosted applications, where tighter valve control is essential for maximizing engine performance.
