Most modern GM engines operate in a split personality, constantly toggling between four and eight cylinders to chase fuel efficiency. This constant transition often invites long-term reliability issues that far outweigh the minor gas savings.
You do not have to accept these mechanical headaches as a permanent feature of your truck. Choosing the Best Afm Delete Kits forces your engine to run as its engineers originally intended: on all cylinders, all the time. Let’s evaluate the options to find the right fix for your specific motor.
Key Takeaways
- Decide if you prefer a simple electronic plug-in device or a permanent mechanical hardware conversion.
- Verify that the kit's displacement compatibility matches your engine size exactly.
- Confirm whether a camshaft replacement is required for your specific repair path.
- Check if the package includes essential gaskets and bolts to ensure a complete seal during reassembly.
- Prioritize kits that include a valley cover plate if you are performing a full hardware delete.

Frequently Asked Questions
Will an AFM delete kit improve my fuel economy?
Actually, the opposite is often true. The AFM system is designed to save fuel by shutting down cylinders during light cruising. By removing it, you will likely see a slight decrease in highway miles per gallon.
Is it possible to install these kits at home?
You can do this yourself if you have a well-equipped garage and experience with engine teardowns. It requires removing the cylinder heads, which is a major job. If you lack the proper torque wrenches or mechanical confidence, hire a professional.
Does deleting AFM increase engine power?
Deleting the system does not magically add horsepower on its own. However, it allows you to install a performance camshaft that significantly increases output. The delete is primarily a reliability upgrade to prevent future lifter failures.
Will this process void my vehicle warranty?
If your car is still under the manufacturer’s warranty, this modification will almost certainly void your coverage. Any powertrain claim will be denied if the dealership sees non-factory valvetrain components. Wait until your warranty expires before committing to this change.
Why do people choose to delete AFM?
The factory AFM lifters are known to fail prematurely, often causing ticking noises or complete engine failure. Many owners delete the system to gain peace of mind and ensure the engine remains reliable for the long haul.
