COMP Cams Valve Spring Kit 0.585in Lift Beehive 06-16 GM 6.6L Duramax Diesel (LBZ/LMM/LML/L5P)

COMP Cams is well-known for making performance valvetrain components, and this Beehive Valve Spring Kit is a prime example of their expertise for GM 6.6L Duramax Diesels. If you're looking to push your engine beyond stock parameters, especially with more aggressive camshafts or increased boost pressures, upgrading your valve springs is a critical step. This kit is designed to handle up to .585 inches of valve lift, giving you the headroom needed for significant performance modifications.

What sets this kit apart is the use of Beehive valve springs. Their unique ovate shape tapers down at the top, allowing for a smaller, lighter retainer. This reduces overall valvetrain weight, which helps the engine rev higher without experiencing valve float. The stronger spring rate and improved dynamic stability of the Beehive design ensure your valves stay seated properly, even under high RPM and boost conditions. This kit includes everything you need for a comprehensive upgrade: the Beehive springs themselves, steel retainers, spring seats, and valve seals, making it a straightforward drop-in replacement for your stock components.

This kit is specifically designed for 2006-2016 GM 6.6L Duramax Diesel engines, covering popular models like the LBZ, LMM, LML, and L5P. When planning your build, remember that while this kit provides the necessary springs and retainers, you'll want to consult the manufacturer's instructions for any specific installation procedures or additional components that might be beneficial for your particular application.
