1.025 Valve Spring - Ovate Beehive (1)

The PAC Racing Springs 1.025 Valve Spring – Ovate Beehive is a precision-engineered component designed for high-performance engine builds where spring rate consistency and durability are critical. This single-unit valve spring features an ovate beehive design, a geometry optimized to reduce stress concentrations and extend service life under sustained high-RPM operation.

Rated at 300 lb/in spring rate with a 1.060-inch coil bind specification, this valve spring delivers predictable load characteristics across the rev range. The 1.025-inch outer diameter (OD) fits standard valve spring pockets found on most small-block and mid-size performance engines, making it a compatible choice for street and competition applications. PAC Racing Springs specializes in manufacturing valve springs to OEM and aftermarket specifications, and the beehive profile on this unit is engineered to minimize coil clash while maintaining consistent preload throughout engine operation.

This spring is intended for builders upgrading factory valve springs or replacing worn components in performance-level engine builds. Users working on carbureted engines, fuel-injected street cars, and track-focused platforms will find this spring suitable where the 300 lb/in rate aligns with their cam profile and valve train geometry. Proper installation requires careful measurement and verification of all valve train clearances, as incorrect spring selection can lead to valve float or excessive wear on rocker arms and pushrods.
