Michigan Motorsports Gen V L87 6.2L DFM Conversion Kit

Fits 2019+ L87 6.2L Gen V LT Engines Only | Complete DFM Conversion Kit with Lifters, Trays, Gaskets, Head Bolts & Oil Block-Off Plugs

Convert your 2019-newer L87 6.2L Gen V LT engine from the factory DFM lifter system with the Michigan Motorsports Gen V L87 6.2L DFM Conversion Kit. Designed specifically for L87 engines only, this kit includes the major components needed to replace the factory DFM active lifter setup with conventional Delphi LS7-style hydraulic roller lifters. This package is ideal for L87 lifter failure repairs, camshaft upgrades, valvetrain service, and performance-focused Gen V LT builds where long-term reliability matters. With DFM port oil block-off plugs, OEM GM head bolts, Gen V 6.2L MLS head gaskets, Delphi LS7-style lifters, non-DOD lifter guide trays, and MLS exhaust manifold gaskets, this kit gives builders a strong foundation for a proper L87 DFM system conversion.

Key Features & Benefits

• Built Specifically for L87 6.2L Engines: This Michigan Motorsports kit is designed for 2019-newer Gen V L87 6.2L engines only, making it a focused solution for late-model GM truck and SUV applications using the L87 DFM lifter system. It will not work with L86, LT1, or LT4 engines.
• Complete DFM Conversion Package: Includes the major components needed when converting from the factory DFM active lifter setup to conventional hydraulic roller lifters. This kit helps simplify the parts list for L87 lifter failure repairs, camshaft service, and Gen V valvetrain upgrades.
• Includes Delphi LS7-Style Lifters & Non-DOD Trays: The kit includes a complete set of 16 Delphi LS7-style hydraulic roller lifters and 4 non-DOD lifter guide trays. This combination is commonly used for conventional lifter conversions and supports a cleaner, more reliable valvetrain setup when paired with the correct camshaft and calibration.
• DFM Oil Block-Off Plug Set Included: The included DFM oil block-off plug set is designed to properly address the DFM oil control passages during conversion. This is a critical supporting component when removing the factory DFM lifter function from a compatible L87 engine.
• Top-End Gaskets & Head Bolt Hardware Included: This kit includes OEM GM head bolts for both cylinder heads, Gen V 6.2L MLS head gaskets, and MLS exhaust manifold gaskets. These components help support a complete cylinder head removal and reassembly process during L87 lifter and camshaft service.

Kit Includes

• (1) DFM solenoid port oil block-off plug set (Brand may vary based on availability)
• (1) OEM GM head bolt kit for both cylinder heads
• (2) Gen V 6.2L MLS head gaskets - replaces 12688943
• (16) Delphi LS7-style hydraulic roller lifters - complete set of 16

• (2) MLS exhaust manifold gaskets

Important Installation Notes

• Non-DFM Camshaft Required: A non-DFM camshaft must be installed when completing this conversion.
• Optional Camshaft Available: Michigan Motorsports offers a 6.2L AFM/DFM conversion camshaft with the same specs as the stock L87 camshaft, but without the DFM lobes.
• ECU Calibration Required: The DFM system must be programmed off in the vehicle’s computer.
• Head Bolt Thread Cleaning: It is highly recommended to clean the head bolt threads in the block with a thread chaser such as ARP 912-0016 before installing new fasteners.
• Fastener Warning: Factory thread compound can remain in the block threads. Failure to clean the threads properly can cause new fasteners to stretch or break before reaching final torque.
• Engine Verification: Please contact sales@michiganmotorsports.com if you are unsure which engine you have.
