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.

Great Replacement
The good. A perfect fit for my left turn signal lamp. 2003 BMW 330XI. Works and looks good. Has weather seal. We will see how it stands up to the Florida rain and car washes. The bad: As you can see in the picture the right lens retainer clip came in broken, Probably damaged in shipping. No big deal I just needed the left, I'll probably just super glue it and store it as a spare. Overall I got my moneys worth and I'm happy. Product was as described and arrived on time. I will buy from this seller again.
