Show original supplier description
The Michigan Motorsports Beehive LS6 Single Valve Spring & Seal Package provides a significant upgrade for LS-based engines, offering enhanced reliability and durability. This comprehensive kit includes 16 LS2/LS3/LS6 beehive-style springs and 16 matching LS hat valve seals, engineered specifically for stock valve guides with integrated spring locators. The springs are designed to support camshafts with a maximum lift capability of up to .550", making them suitable for both street performance and more demanding builds. Key specifications for this package include an installed height of 1.800" measured at 90 lbs. of seat pressure, and an open height of 1.250" at 295 lbs. of open pressure. These specifications ensure consistent valve control and proper operation across a range of engine conditions. The springs directly replace GM part numbers 12499224 and 12713265. This valve spring and seal package is broadly compatible with popular LS engine platforms, including LS1, LS6, LS2, and LS3, as well as a variety of GM truck engines. However, it is important to note that this specific setup is not compatible with dual valve spring configurations. Ensure your existing setup is a single valve spring design before installation.
