Michigan Motorsports Gen IV 2007-2014 AFM/DOD Conversion Kit

Fits Gen IV 6.0L & 6.2L LS-Based V8 Engines | Includes ICT Billet Valley Cover, Delphi LS7 Lifters, Trays, Gaskets & Head Bolts

Convert your Gen IV 6.0L or 6.2L LS-based engine from the factory AFM/DOD lifter system with the Michigan Motorsports Gen IV 2007-2014 AFM/DOD Conversion Kit. Built for common 6.0L and 6.2L Gen IV LS truck, SUV, and performance applications, this complete package includes the major components needed to replace the factory active lifter setup with conventional Delphi LS7-style hydraulic roller lifters. This kit is an excellent choice for lifter failure repairs, camshaft upgrades, performance builds, and long-term valvetrain reliability improvements. With Delphi LS7 lifters, GM lifter guide trays, LS9-style MLS head gaskets, head bolts, MLS exhaust gaskets, and an ICT Billet valley cover with oil sensor adapter, this kit gives builders a strong foundation for a proper AFM/DOD system conversion.

Key Features & Benefits

• Complete Gen IV AFM/DOD Conversion Package: Designed for 6.0L and 6.2L Gen IV LS-based engines, this kit includes the core lifter, tray, gasket, valley cover, and head bolt components needed when converting from the factory active lifter system to a conventional lifter setup.
• Includes Delphi LS7 Lifters & GM Lifter Trays: The kit includes a set of 16 Delphi LS7 hydraulic roller lifters and 4 GM lifter guide trays, giving you the lifter and tray combination commonly used for conventional LS valvetrain conversions, lifter failure repairs, and performance camshaft upgrades.
• ICT Billet Valley Cover Included: Includes an ICT Billet AFM/DOD conversion valley cover with oil sensor adapter, seal, and bolts. This gives the engine a clean, purpose-built valley cover solution when moving away from the factory AFM/DOD valley cover configuration.
• Top-End Gaskets & Head Bolts Included: The kit includes 6.0L / 6.2L MLS LS9-style head gaskets, two LS head bolt kits, and a pair of LS multilayer exhaust manifold/header gaskets. These supporting components help simplify the parts list when the cylinder heads are removed for lifter and camshaft service.
• Ideal for Repairs, Cam Upgrades & Performance Builds: Perfect for Gen IV LS engines being repaired after active lifter failure, upgraded with a non-DOD camshaft, or refreshed for improved valvetrain reliability. This package helps shops, builders, and DIY LS owners complete the job with the correct supporting parts in one kit.
