GEN 5 Beehive Springs - .550 Lift (16)

The GEN 5 Beehive Springs - .550 Lift (16) by Brian Tooley Racing deliver a complete valve spring upgrade for serious small-block Chevrolet and modern engine builders seeking reliable high-lift cam support. These performance springs are engineered to handle aggressive camshaft profiles, higher rocker ratios, and extended valve events without valve float or coil bind. Whether you're building a street performance engine, weekend drag racer, or road course competitor, these springs provide the geometric control and consistent preload necessary to maximize cam potential while maintaining valve train stability across the entire RPM band.

Brian Tooley Racing's beehive design minimizes spring mass and inertial load, reducing stress on pushrods, rocker arms, and cam lobes—critical when running .550-inch lift profiles on factory or upgrade cylinder heads. The tapered cone geometry provides superior seating force consistency and better off-seat response compared to conventional cylindrical springs. This set of sixteen springs (eight intake and eight exhaust) ensures matched load curves across all eight cylinders, preventing individual spring variation that causes uneven valve timing and combustion instability. The .550 lift specification accommodates cam lobes with higher intensity profiles while maintaining safe coil clearances and proper installed heights for both stock and ported heads.

Installation requires proper spring height measurement, seat pressure validation, and correct rocker arm geometry confirmation before final assembly. These springs pair ideally with roller rockers, upgraded pushrods, and performance cylinder heads designed for extended valve events. Builders upgrading from mild factory springs to this .550-lift package will immediately notice sharper throttle response, higher RPM capability, and cleaner power band characteristics. Verify your head's maximum lift capacity and spring pocket depth before ordering—incompatible installations risk float, binding, or premature failure. Brian Tooley Racing springs are trusted by engine shops and performance enthusiasts for repeatability and durability across thousands of miles and countless dyno pulls.
