Texas Speed DOD DFM Hole Plugs for 2019+ Gen 5 LT Engines
Fits 2019+ GM Truck & 2021+ SUV Gen V LT L84 L87 L82 Engines | 8th Digit VIN D, L, or F | DFM/DOD Block Plug Kit
Complete your Gen V LT DFM/DOD conversion properly with the Texas Speed DOD DFM Hole Plugs for 2019+ GM LT-based engines. These plugs are designed for newer Gen 5 LT truck and SUV engines that use DFM solenoids located in the engine block instead of being built into the valley cover like earlier Gen V applications. This makes them an important component when converting 2019+ L84, L87, and L82 engines to conventional lifters. Ideal for 2019-newer GM trucks and 2021-newer GM SUVs with 8th digit VIN D, L, or F, this plug kit helps seal the DFM/DOD solenoid locations in the block during a proper lifter system conversion.
Key Features & Benefits
- Designed for 2019+ Gen V LT DFM Engines: This Texas Speed plug kit is built for late Gen 5 LT truck and SUV engines that have DFM solenoids located directly in the engine block. These are different from earlier Gen V engines where the system was incorporated into the valley cover, making the correct plug kit critical for proper conversion work.
- Fits L84, L87 & L82 Applications: Compatible with 2019+ GM truck and 2021+ SUV applications equipped with Gen V LT L84, L87, and L82 engines. These engines are commonly found in late-model GM 5.3L and 6.2L truck/SUV platforms using the updated DFM lifter system.
- Required for Proper DFM/DOD Block Conversion: When converting from the factory DFM/DOD lifter system to conventional lifters, the block solenoid locations must be properly addressed. These hole plugs are designed to seal those locations as part of a complete and correctly planned conversion.
- Ideal for Lifter Failure Repairs & Performance Builds: Late-model LT engines can require valvetrain service due to lifter issues, camshaft upgrades, or performance rebuilds. This plug kit is a key supporting component when moving to conventional lifters for improved simplicity, durability, and long-term serviceability.
- Texas Speed Conversion Component: Built for builders, shops, and DIY LT owners completing a Gen V DFM/DOD conversion the right way. Pairing the correct block plugs with conventional lifters and proper calibration work helps ensure the engine is assembled safely and functions as intended.
Important Installation Notes
- Conventional Lifters Required: This plug kit is intended for use when converting the engine to conventional non-DFM / non-DOD lifters.
- ECU Calibration Required: The DFM/DOD system must be turned off in the vehicle’s computer as part of the conversion process.
- Application Style: Designed for engines with DFM solenoids located in the block, not earlier valley-cover-style DOD/AFM systems.
