Does your Chevy or GMC truck feel sluggish when you need real power? Many truck owners know that feeling. The Active Fuel Management (AFM) system, while good for saving gas on the highway, often hinders performance when you want to accelerate quickly or tow heavy loads. Removing this system can unlock your engine’s true potential, but picking the right AFM delete kit *and* the perfect camshaft is where things get tricky.
Choosing the right combination can lead to headaches. You worry about compatibility, rough idling, or whether the new cam will truly deliver the horsepower you crave. It’s a big investment, and you need to get it right the first time. This guide cuts through the confusion.
We break down exactly what you need to know about the top 5.3 AFM delete kits paired with performance cams. By the end of this post, you will understand the best options for your truck’s goals, whether you seek better street manners or serious towing muscle. Let’s dive in and transform your engine’s performance!

The Ultimate Buying Guide: Upgrading Your 5.3L AFM Engine
If you own a GM truck or SUV with the popular 5.3L V8 engine, you might be familiar with Active Fuel Management (AFM). AFM shuts down cylinders to save gas. However, many owners choose to delete this system. A 5.3 AFM Delete Kit with Cam is a popular upgrade. This guide helps you choose the right kit.
Key Features to Look For
When shopping for an AFM delete kit, look for specific parts that make the swap successful and reliable.
- **AFM Delete Controller/Lifter Trays:** This is the core of the kit. It stops the engine computer from trying to run the AFM system. Make sure the kit includes hardware to replace the faulty AFM lifters.
- **Camshaft (The “With Cam” Part):** A good delete kit usually includes a performance camshaft. This cam must be designed to work with the non-AFM lifters. Look for a cam that matches your driving style (towing, daily driving, or performance).
- **Necessary Gaskets and Seals:** A quality kit includes everything needed for installation. You do not want to start the job only to find you are missing a simple valve cover gasket.
Important Materials
The materials used in the components affect how long they last.
The **lifters** are crucial. Standard, high-quality replacement lifters are much stronger than the original AFM lifters. Look for kits that use **billet steel** components where possible. Billet parts are stronger than cast parts. The **camshaft** should be made from strong, heat-treated steel. This helps it handle the extra stress from the performance grind profile.
Factors That Improve or Reduce Quality
Quality matters a lot for long-term engine health.
What improves quality? A kit that includes a **high-quality DOD (Displacement on Demand) delete block-off plate** ensures no oil leaks from the removed solenoids. Also, kits that come with detailed, easy-to-follow instructions improve the overall experience.
What reduces quality? Using very cheap, unbranded lifters significantly reduces quality. If the replacement cam profile is too aggressive for your stock valve springs, it can cause valve float—which damages the engine. Always check compatibility between the cam and the springs.
User Experience and Use Cases
Why do people install these kits? The user experience changes significantly after installation.
The primary goal is **reliability**. Deleting AFM removes a common failure point in the 5.3L engine. You stop worrying about lifter failure or excessive oil consumption related to the system.
The second use case is **performance**. The new camshaft changes how the engine breathes. For a daily driver, you want a cam that adds horsepower without causing a rough idle. For a truck used for towing, you need torque across the mid-range RPMs. Always match the cam grind to your intended use.
10 Frequently Asked Questions (FAQ) About 5.3 AFM Delete Kits with Cam
Q: Does this kit improve gas mileage?
A: Generally, no. You lose the cylinder deactivation feature, so gas mileage might slightly decrease. The trade-off is better reliability and more power.
Q: Will my truck still pass emissions testing?
A: Yes, usually. You must have the Engine Control Unit (ECU) professionally tuned after installation. The tuner will turn off the AFM codes so the check engine light stays off.
Q: How long does the installation take?
A: For an experienced mechanic, it takes about a full day (8-10 hours). If you are doing it yourself, plan for two full days, as you must remove the cylinder heads to swap the lifters and cam.
Q: Do I need to buy new cylinder head bolts?
A: Yes, almost always. GM recommends using new Torque-to-Yield (TTY) head bolts when reinstalling the heads. Reusing old bolts can lead to future head gasket leaks.
Q: What is the difference between this kit and just deleting the AFM solenoids?
A: Deleting only the solenoids leaves the weak AFM lifters inside the engine. They can still fail. A full kit replaces those weak lifters with strong, standard ones, solving the root problem.
Q: Can I use my stock torque converter with a new cam?
A: For mild cams, yes, you can reuse the stock converter. If the cam is very aggressive and adds a lot of power, a higher stall torque converter is recommended for better performance when starting from a stop.
Q: What is the most important thing to tune after installing the cam?
A: The timing tables and fuel maps are most important. The new cam changes how air enters and leaves the engine, so the computer needs new instructions to run smoothly.
Q: Are these kits compatible with forced induction (superchargers/turbos)?
A: Some kits are, but you must choose a cam specifically designed for boosted applications. A standard delete cam might not work well with a supercharger.
Q: Does this delete kit affect oil pressure?
A: No. The deletion process generally does not affect the oil pump. However, ensure you use the correct viscosity oil recommended for your specific new cam manufacturer.
Q: What RPM range is best for the new cam?
A: This depends entirely on the cam you select. Daily drivers usually have a flat power band (good power from 2,000 to 5,800 RPM). Towing cams focus power lower down.
