Product Description
Michigan Motorsports Gen V L83 5.3L AFM/DOD Delete Kit
Fits 2014–2020 5.3L L83 L8B (8th Digit of VIN = C or R Only)
The Michigan Motorsports Gen V L83 5.3L AFM/DOD Delete Kit provides the core components required to convert your 2014–2020 L83 or L8B engine from Active Fuel Management (AFM/DOD) to a traditional non-DOD valvetrain setup. This kit is designed specifically for engines where the 8th digit of the VIN is C or R. It will NOT fit L84, L82, or engines not listed.
Ideal for camshaft upgrades or long-term reliability builds, this kit includes premium sealing components, head bolts, lifter trays, and your choice of Delphi LS7-style lifters (8 or 16). A non-DOD camshaft and proper ECM programming are required to complete the conversion.

Key Features & Benefits
- Designed for L83 & L8B (VIN C or R): Engineered specifically for 2014–2020 5.3L engines where the 8th digit of the VIN is C or R.
- Complete AFM/DOD Conversion Hardware: Includes oil galley block-off plugs, head bolts, gaskets, lifters, and trays required for a proper mechanical conversion.
- Delphi LS7 Style Lifters: Proven OEM-quality lifters ideal for stock rebuilds or performance camshaft upgrades (no manufacturer warranty on lifters).
- MLS Head Gaskets & New Head Bolts: High-quality multi-layer steel gaskets and new torque-to-yield head bolts ensure proper sealing.
- OEM Valley Cover Compatible: Block-off plugs are designed for use with the original DOD/AFM valley cover configuration.
Important Notes
A non-DOD camshaft must be installed, and the DOD/AFM system must be disabled in the vehicle’s computer for proper operation. The included oil block-off plugs are for use only with the original DOD/AFM valley cover and will not fit non-DOD or aftermarket DOD delete valley covers.
On these engines it is highly recommended to clean out the head bolt threads in the block with a chaser such as ARP 912-0016 due to the thread compound that was used on the factory bolts. Failure to do so can result in new fasteners stretching or breaking before reaching final torque.
