The Texas Speed 2019+ LT DOD Hole Plugs Kit is used when the factory DOD/AFM system is removed from a 2019 and newer GM Gen V LT truck or SUV engine. Once the DOD solenoids are pulled from the block, the plugs in this kit close the oil solenoid ports and the OEM valley cover so the engine keeps correct oil flow without the deactivation hardware.
Texas Speed lists the kit for the 5.3L L84 and 6.2L L87, covering 2019 and newer GM trucks and 2021 and newer GM SUVs. It is one piece of a DOD delete and must be paired with a non-DOD camshaft and matching lifters; Texas Speed notes that removing DOD improves lifter durability and long-term engine reliability on these newer V8s.

FAQ
What engines does the Texas Speed 2019+ LT DOD Hole Plugs Kit fit?
Texas Speed lists the kit for the Gen V 5.3L L84 and 6.2L L87 in 2019 and newer GM trucks and 2021 and newer GM SUVs. It is not listed for the earlier 2014 to 2018 L83 and L86 engines.
What is included in the DOD hole plugs kit?
The kit includes the plugs for the DOD oil solenoid ports in the block and a plug for the factory valley cover, so the openings left by the removed solenoids are sealed while oil flow stays as designed.
Can I install these plugs and keep the factory camshaft?
No. Texas Speed states the kit must be used with a non-DOD camshaft and the appropriate lifters. The plugs only close the solenoid ports; the DOD lifters and camshaft must be replaced as part of the delete.
Why delete DOD on a 2019+ GM truck?
Texas Speed notes that DOD removal improves lifter durability and overall engine lifespan and reduces the risk of the lifter failures commonly seen in newer GM V8s. The engine then runs on all eight cylinders at all times.
Does a DOD delete require tuning?
Yes. After the solenoids are removed and a non-DOD camshaft and lifters are installed, the ECM must be calibrated to disable Active Fuel Management so it no longer tries to deactivate cylinders.
