The difference between a reliable engine and a high-maintenance headache often comes down to the quality of the lifters included in your kit. Dodging the persistent failure points of Active Fuel Management systems requires a permanent mechanical fix rather than a temporary electronic band-aid.
You want a complete solution that restores longevity to your truck. These Best Dod Delete Kits offer a path to consistent performance for your engine. Read on to see which components you actually need to finish the job correctly.
Key Takeaways
- Prioritize kits that include new head bolts and gaskets to ensure a proper seal after you pull the cylinder heads.
- Verify that your kit includes a non-AFM specific valley cover plate to correctly route your oil pressure.
- Choose a camshaft profile that matches your vehicle's specific engine displacement to avoid idle and tuning issues.
- Check if your kit includes an oil pump, as some high-mileage engines benefit from improved pressure after a lifter swap.
- Remember that hardware kits are useless if they lack the specialized guides or thrust plates required for your specific Gen IV or Gen V engine block.

Frequently Asked Questions
Do I need to reprogram my computer after installing a delete kit?
Yes, you must update your Engine Control Module to disable the DOD system. If you do not perform a software tune, the computer will attempt to engage solenoids that are no longer there, leading to check engine lights and poor performance.
Is it possible to perform this work without removing the cylinder heads?
Unfortunately, no. Because the DOD lifters are located deep within the engine block, you have to remove the cylinder heads to access them. This makes the job a significant project that requires a full weekend of time.
What are the main benefits of deleting the DOD system?
The primary benefit is improved reliability for your valvetrain. By removing the complex electronic solenoids and specialized lifters, you eliminate the most common points of failure in the engine, which gives you peace of mind during high-RPM driving.
Will deleting the system change my fuel economy?
You might notice a slight decrease in highway fuel efficiency. Since the engine will no longer enter a cylinder-deactivation mode, it will burn more fuel while cruising at steady speeds.
Can I use the original camshaft with a delete kit?
You technically can, but it is highly discouraged. The original camshaft has specific DOD lobe profiles that will not optimize your performance, and it often leads to a rough or inefficient combustion cycle.
