Michigan Motorsports .600" Lift Beehive Valve Springs deliver high-quality performance at a competitive price, developed in partnership with a Tier 1 OEM supplier. Designed for LS engines running aftermarket camshafts up to .600" lift, these springs provide the ideal combination of durability, stability, and improved valvetrain control. They are a premium alternative to popular PAC 1218/1219 springs, making them a go-to choice for owners of Elgin Sloppy cams, Michigan Motorsports Lumberjack High-Lift kits, and .550"–.560" truck camshafts—especially on 2007+ rectangle-port engines with heavier intake valves requiring additional spring pressure.

Top notch quality and service
I installed these springs on my LQ9 317 heads. They worked with my OE retainers. They will be used in combination with the 1839p Elgin camshaft. I had emailed customer service with my questions and they went above and beyond to answer everything and help me out. A great product and an excellent customer service experience will have me coming back for my future needs.
