1.061 Valve Springs - Ovate Beehive (16)

The PAC Racing Springs 1.061 Valve Springs – Ovate Beehive (16) set delivers precision performance for LS-series engine builds. These high-quality valve springs are engineered for applications requiring reliable spring rates and consistent performance across RPM ranges. Set of 16 springs meets the demands of custom engine builders and motorsports enthusiasts seeking OEM-quality components with verified specifications.

Each spring features a 1.061-inch outer diameter with a 275 lb/in spring rate, designed to maintain proper valve control while the 1.013-inch coil bind specification prevents over-compression during maximum lift events. The ovate beehive design optimizes spring geometry for efficient load distribution and reduced harmonics, critical factors in high-performance LS applications. PAC Racing Springs' manufacturing tolerances ensure consistent performance across all 16 springs in the set, eliminating variances that could affect engine reliability or response characteristics.

This spring set is specified for GM LS-series engines, making it suitable for crate engine builds, performance restorations, and track-focused applications. Engine builders and tuners rely on PAC Racing Springs for valve train components where spring rate precision directly impacts camshaft compatibility, valve timing accuracy, and overall engine stability. Whether building a street performance engine or preparing for competition use, matching the correct spring rate to your specific camshaft profile and intended RPM range is essential for sustained reliability.

LS-series engines are the platform of choice for engine swaps, restorations, and performance builds across multiple vehicle platforms. The modular design of LS architecture allows builders to select complementary components—springs, retainers, pushrods, and lifters—based on specific camshaft and performance targets. These PAC Racing valve springs integrate seamlessly into complete valve train assemblies and are engineered to meet industry standards for LS applications.
