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

The .585” Lift COMP Cams Beehive Valve Spring Kits for GM 6.6L Duramax Diesel Engines include everything needed to upgrade from stock springs: Beehive Valve Springs, steel retainers, spring seats and valve seals. Beehive Valve Springs feature a reduced diameter at the top of the spring to allow the use of a smaller and lighter retainer, reducing overall valve train weight. The lighter valve train combined with the stronger spring allows the engine to rev higher without concerns of valve float while an increased spring rate maintains valve train stability at elevated RPM to allow the use of more aggressive camshafts. The unique ovate Beehive shape not only has higher load but is more dynamically stable than the factory spring, ensuring valve train stability at elevated RPM and boost pressures.

Able to support .585" valve lift, this Beehive Spring Kit for '06-'16 Duramax Diesels includes springs, retainers, seats and seals for an easy drop-in upgrade. Thanks to a unique Ovate Beehive design, this kit handles higher RPM and boost.

Valve springs are one of the most critical and overlooked components in your engine. They must be matched to your cam in order for the engine to reach its full potential. It does absolutely no good to install a cam that will perform up to 8,000 rpm if you do not have the correct springs. Use the only valve springs that will give the recommended spring pressure with the valve both on the seat and at maximum lift. COMP Cams valve springs are offered in single and dual styles to meet your cam requirements.
