LS6 Beehive Springs .560 Lift (16)

The LS6 Beehive Springs .560 Lift (16) from Brian Tooley Racing represents a precision valve spring upgrade designed specifically for high-performance LS6 engine builds and modified Gen IV/V LS powerplants. As an experienced mechanic, you'll recognize that stock LS6 springs are engineered for factory cam profiles and RPM limits; upgrading to a dedicated beehive-design spring is essential when installing aggressive aftermarket camshafts, increasing valve lift, or pushing engine speed beyond 6,500 RPM. This set of 16 springs delivers the valve control and reliability needed to prevent valve float, spring surge, and catastrophic engine damage during sustained high-RPM operation.

Beehive springs are manufactured with a tapered, nested coil design that reduces spring weight and inertia compared to traditional cylindrical springs, improving valve response and reducing valvetrain stress at elevated RPMs. The .560-inch lift specification means these springs are calibrated to safely control valve events up to approximately .560 inches of valve lift—a common requirement for street and strip LS6 builds paired with moderate to aggressive hydraulic roller cams. Brian Tooley Racing engineers these springs to precise tension specifications, ensuring consistent seat pressure and open-height performance across all 16 units. The compact 10.35-inch package makes handling and installation straightforward during a valvetrain refresh or complete LS engine assembly.

This spring set is ideal for LS6 owners upgrading to cam profiles in the .520–.560 lift range, whether you're building a weekend race engine, a street machine targeting consistent mid-range power, or a crate-motor application. Installation requires removal of valve covers and rocker arms, making it a practical upgrade to pair with a complete valvetrain refresh, which allows you to inspect and replace related components like pushrods, rocker arms, and lifters in one service interval. Confirm compatibility with your specific cam profile and rocker arm geometry before ordering—Brian Tooley Racing technical support can verify compatibility with your exact build configuration. Proper spring installation with a compressor tool is essential to ensure even seating and longevity.
