This Michigan Motorsports Gen V .550 lift valve spring kit is engineered for GM LT-based engines requiring increased spring capacity to support performance camshafts while maintaining reliability and proper valvetrain control. Designed for 2014 and newer LT platforms, these beehive valve springs provide improved seat and open pressure to prevent valve float and maintain stable valve motion at higher RPM. Ideal for camshaft upgrades, engine rebuilds, and performance refreshes, this kit supports consistent operation without sacrificing street manners when paired with compatible components. Built for durability and precise fitment, it is a dependable solution for Gen V LT engines running higher lift cam profiles up to .550 inch.

  • .550 Lift Capability: Designed to safely support camshafts up to .550 valve lift, providing proper valvetrain control for performance LT engine applications.

  • Ideal for Camshaft Upgrades: Commonly used during cam installs and engine rebuilds to ensure reliable valve control and long-term durability.
