The rhythmic tapping sound coming from your engine bay is a constant reminder that the Active Fuel Management system is struggling. That familiar tick signals that your lifters are failing, turning a reliable workhorse into a source of frustration.
Switching to a non-AFM setup restores the mechanical simplicity your engine deserves. Choosing the Best 5.3 Afm Delete Kits with Cam ensures you stop the cycle of lifter failure once and for all. Keep reading to see which kits simplify this essential repair.
Key Takeaways
- Verify that the camshaft profile is compatible with your specific model year, as GM changed key engine components between 2013 and 2014.
- Always check that the kit includes the full head gasket set, because reusing old seals is a recipe for a coolant leak.
- Prioritize kits that include a fresh timing chain, as high mileage engines often need a tighter, more reliable tensioner system.
- Match your camshaft duration to your actual driving habits to ensure you do not lose low-end torque during daily towing or hauling.
- Confirm that the replacement lifters are standard non-AFM units, as these lack the failure-prone oil passages of the factory parts.

5.3L AFM Delete Timing Kit
If you are worried about the wear on your timing components, this kit is your best friend. It includes the essential timing chain kit alongside the camshaft and lifters, which makes it a much more thorough replacement package than basic cam kits.
The inclusion of the chain allows you to refresh the entire valve train assembly at once. It is an excellent option for engines with higher mileage where the timing chain might already have a bit of slack. You should prepare for a lengthy installation process, as this requires accessing the front of the engine block.
- Included Components:Cam, lifters, head gaskets, timing kit
- Engine Type:5.3L V8
- Additional Feature:Prevents future timing slip
- Additional Feature:Simplifies engine block restoration
- Additional Feature:Complete valvetrain refresh

Frequently Asked Questions
Do I need to remove the cylinder heads to install a new cam?
Yes, replacing the camshaft in a 5.3L engine requires removing the cylinder heads to access the lifters. Since you are already in there, it is standard practice to replace the head gaskets and head bolts.
Will deleting AFM improve my gas mileage?
You should not expect a noticeable increase in fuel economy after this conversion. While the system was designed for efficiency, the primary benefit here is engine reliability and the ability to run a performance camshaft.
Can I reuse my old pushrods with the new cam?
It is rarely a good idea to reuse old pushrods when installing a new camshaft. A different cam profile often requires a specific pushrod length to maintain the correct valvetrain geometry.
Is a professional tune absolutely necessary?
A custom tune is mandatory for this process to succeed. The computer will be looking for the AFM system that you just removed, and it will cause performance issues if it is not electronically disabled.
How long does the installation process typically take?
If you have the right tools and workspace, this is usually a multi-day project. Even for experienced hands, clearing space for the cam swap and replacing the lifters requires careful precision and patience.
