Factory cylinder deactivation systems used to be a point of pride for fuel economy. Today, they are a notorious headache for truck owners who prefer reliable performance over minor efficiency gains.
Swapping out these problematic lifters is the standard path to a healthier engine. Finding the Best 5.3 Afm Delete Kits with Cam requires sorting through specific hardware lists, so here is the breakdown of your top choices.
Key Takeaways
- Verify that your kit includes new head bolts, as the factory torque-to-yield hardware cannot be reused.
- Ensure the camshaft profile is compatible with your specific ECM calibration to prevent check engine lights.
- Prioritize packages that provide lifter trays along with the lifters to maintain proper alignment during high-RPM operation.
- Confirm the gasket set includes a valley cover block-off plate, which is essential to eliminate the AFM oil feed system.
- Check if your engine requires the VVT lockout hardware, as many delete kits do not include the cam phaser limiter.
