The Ultimate Buying Guide: Choosing Your AFM Delete Kit
If your vehicle has an Active Fuel Management (AFM) system, you might be thinking about removing it. An AFM Delete Kit helps your engine run more consistently. This guide will help you pick the right one.
Key Features to Look For
When shopping for an AFM Delete Kit, several features matter most. These features ensure your kit works well and lasts long.
- Compatibility: Make sure the kit fits your specific year, make, and model of truck or SUV. A wrong fit means the kit will not work.
- Lifter Type Included: Good kits come with new, non-deactivating lifters. These replace the weak AFM lifters.
- Camshaft Specs: Check if the kit includes a new camshaft. If it does, ensure the cam grind matches your driving style (daily driving or heavy towing).
- Tuner/Programmer: Most kits require tuning. See if the seller includes a handheld tuner or if you must buy one separately.
Important Materials That Make a Difference
The quality of the materials directly affects how long your engine runs smoothly after the delete.
Lifter Construction
Look for lifters made from strong, hardened steel. Cheap, lightweight materials wear out fast. High-quality lifters handle higher oil pressure better. You want lifters that will not fail like the original AFM ones did.
Gaskets and Seals
The kit must include high-quality gaskets. Silicone or MLS (Multi-Layer Steel) head gaskets are best. Poor gaskets leak oil or coolant, causing big problems later.
Pushrods
Stock pushrods sometimes stretch after AFM removal. Strong, one-piece chromoly pushrods offer better stability and precision inside the engine. These are a smart upgrade.
Factors That Improve or Reduce Quality
What makes one kit better than another? It often comes down to the supporting parts.
Quality Boosters
Kits that include a complete valley cover and new oil pump gears usually offer better overall quality. A quality tuning file (the software update) is also essential. A good tune makes sure the engine runs perfectly after the swap.
Quality Reducers
Avoid kits that only include cheap lifters and skip the necessary timing set upgrade. Some budget kits might save money by using stock-style head bolts instead of stronger aftermarket bolts. These bolts can sometimes fail under stress, reducing the quality of the repair.
User Experience and Use Cases
Why do people install these kits? The experience changes significantly.
The Driving Experience
After the delete, your engine will operate on all cylinders all the time. Users often report smoother idle quality and less hesitation when accelerating. The main benefit is peace of mind; you eliminate the risk of costly AFM lifter failure.
Installation and Tuning Use Cases
Installing an AFM delete kit is a major repair. It requires removing the cylinder heads. This job is complex. Most everyday mechanics should not attempt this without experience. Professionals usually need several hours to complete the physical swap. After installation, the vehicle absolutely must be professionally tuned. Driving the truck without the correct tune can damage the engine.
AFM Delete Kit FAQ
Q: What is the main reason for installing an AFM Delete Kit?
A: The main reason is to prevent catastrophic engine failure caused by the original AFM lifters failing. It also provides more consistent engine performance.
Q: Do I need to tune my truck after installing the kit?
A: Yes, tuning is mandatory. The computer needs to know the AFM system is gone so it does not try to deactivate cylinders.
Q: Can I reuse my original head bolts?
A: Many mechanics advise against reusing old Torque-to-Yield (TTY) head bolts. Quality kits include new, stronger head bolts for a better seal.
Q: Will this kit hurt my gas mileage?
A: You might see a small drop in highway gas mileage because the engine is no longer running on four cylinders sometimes. However, this small loss is usually worth the reliability gain.
Q: How long does the installation usually take?
A: For an experienced mechanic, the physical installation can take 8 to 12 hours. This includes removing the top end of the engine and putting it back together.
Q: Are AFM Delete Kits legal everywhere?
A: In most places, removing the AFM system is legal for repair purposes. However, some strict states have emission laws that might question modifications that affect fuel economy.
Q: What is the difference between a delete kit and a range device?
A: A delete kit permanently removes the faulty hardware. A range device simply tricks the computer into staying in V8 mode; it does not fix the underlying weak lifters.
Q: What kind of lifters should the kit include?
A: The kit should include full replacement lifters that are specifically designed not to rely on the AFM oil system. Look for “non-AFM” or “AFM delete specific” lifters.
Q: Will this delete kit affect my warranty?
A: Yes, installing any major powertrain modification will void any remaining powertrain warranty from the manufacturer.
Q: Can I tow heavy loads safely after installing this kit?
A: Absolutely. In fact, many people install these kits specifically because they tow heavy loads. The engine runs stronger and more reliably under strain.
