The Ultimate Buying Guide for Your 5.3 AFM Delete Kit With Cam
Upgrading your 5.3L engine with an Active Fuel Management (AFM) delete kit paired with a new camshaft can seriously boost your truck or SUV’s performance and sound. This guide helps you pick the right kit.
Key Features to Look For
When shopping for a 5.3 AFM delete kit with a cam, several features make a big difference in how well the system works.
- **Complete Kit Contents:** Ensure the package includes everything you need. A good kit must have the AFM delete controller (or plug), a new lifter tray, a new timing set, and the camshaft itself. Missing parts mean extra trips to the store.
- **Camshaft Specs:** Look at the cam’s duration and lift numbers. These numbers tell you how aggressively the engine breathes. A mild cam offers better street manners and fuel economy. A bigger cam provides more top-end power but might need more tuning.
- **Lifter Quality:** Since you are removing the AFM system, you need standard, robust lifters. High-quality, non-AFM lifters prevent future failure.
- **Gasket Set:** A quality kit includes new head and intake manifold gaskets. These must be made of durable material to prevent leaks after installation.
Important Materials
The materials used directly affect the longevity and performance of the kit.
The camshaft itself is usually made from high-strength steel or iron. Steel cams generally handle more stress if you plan on heavy modifications later. For the lifters, look for ones with stronger roller bearings. The trays that hold the lifters should be sturdy plastic or metal; metal trays last longer.
Factors That Improve or Reduce Quality
Good quality means more power and fewer headaches.
Factors that improve quality: Kits from well-known performance brands usually have better engineering. Using a cam designed specifically for your engine year (LS4, LM7, etc.) improves quality because the computer tuning will be easier. Always choose kits that include new, strong valve springs, as the old ones might be weak with a new cam profile.
Factors that reduce quality: Cheap, no-name kits often use weaker materials. If the kit tries to reuse the factory AFM lifters instead of replacing them, quality drops significantly. Poorly matched valve springs to the new cam cause “valve float,” which hurts performance and can damage the engine.
User Experience and Use Cases
How you plan to use your truck dictates the best kit choice.
Street Driving/Daily Use: If you drive your truck every day, you want a mild cam profile. These kits offer noticeable power gains, a nice rumble at idle, and they keep fuel economy close to stock. The user experience is smooth acceleration and no rough idling.
Towing/Heavy Work: For towing, look for a cam that builds torque lower in the RPM range. This gives you pulling power when you need it most without having to rev the engine very high. The experience is better control under heavy load.
Performance/Racing: If your goal is maximum horsepower, you need an aggressive cam. Be prepared for a rougher idle and potentially worse fuel economy. This choice requires professional tuning to get the most out of the setup.
10 Frequently Asked Questions (FAQ) About 5.3 AFM Delete Kits With Cam
Q: Why do I need to delete AFM in the first place?
A: The AFM system uses special lifters that can fail over time, leading to expensive engine repair. Deleting it removes this weak link.
Q: Will this kit fix my oil consumption issues?
A: Often, yes. AFM lifters and associated components can cause oil burning. Replacing them with standard, quality parts usually solves this problem.
Q: Do I need to tune my truck after installing this kit?
A: Yes, a tune is absolutely required. The new camshaft changes how the engine breathes, and the computer needs new instructions to run correctly.
Q: Can I install this kit myself?
A: This is a complex job that requires removing the cylinder heads. If you are an experienced mechanic, you can do it. For most people, a professional shop should handle the installation.
Q: How much horsepower increase can I expect?
A: With a good cam and proper tuning, you can often see gains between 30 and 60 horsepower, depending on the cam size.
Q: Does this kit change the sound of my engine?
A: Yes. A new cam usually gives the engine a deeper, more aggressive sound, often called a “lope” at idle.
Q: What is the difference between a “delete” and a “conversion” kit?
A: A delete kit removes the AFM hardware completely. A conversion kit often replaces AFM components with non-AFM parts but might leave some original wiring in place.
Q: Will my fuel economy get worse?
A: A mild cam should not hurt economy much. A very aggressive cam will likely decrease your miles per gallon because the engine prefers to run harder.
Q: Which year 5.3L engines does this kit fit?
A: Most kits fit the Gen IV 5.3L engines (roughly 2007–2013), but you must confirm the kit matches your exact engine code (like LMG or LY5).
Q: What is the most important part to upgrade besides the cam?
A: The valve springs are crucial. New springs must match the lift of the new cam to keep the valves working correctly at high RPMs.
