Your Essential Guide to Buying an MDS Delete Kit for Your 5.7L Hemi
If you own a 5.7L Hemi engine, you probably know about the Multi-Displacement System (MDS). This system shuts down cylinders to save gas. Sometimes, though, you want more power or need to fix a problem with the MDS. That’s where an MDS Delete Kit comes in. This guide helps you choose the right one.
Key Features to Look For
When you shop for an MDS Delete Kit, look for specific parts that make the kit work well.
- DOD/MDS Lifters: These are the most important parts. Make sure the kit includes four new lifters designed to work all the time, not just when the MDS is active. Good lifters mean your engine runs smoothly.
- Camshaft: Some kits include a new camshaft. A performance camshaft often gives you better power across the RPM range. Check the lift and duration numbers to see if they fit your driving style.
- Lifter Trays/DOD Delete Trays: These plastic or metal pieces hold the lifters in place. Strong trays keep everything secure inside your engine.
- MDS Plug or Solenoid Eliminator: This small part stops the computer from trying to activate the MDS system. It is crucial for a complete delete.
Important Materials That Matter
The quality of the materials directly affects how long your delete kit lasts. Think about what the parts are made from.
The lifters should use high-quality steel or hardened metal. Cheap metal parts wear out fast. Look for kits that use stronger materials for the springs and lifter bodies. The camshaft, if included, should be ground precisely. Precision grinding ensures it matches your engine’s timing perfectly. Always check if the manufacturer clearly states the material used for critical components like lifters.
Factors That Improve or Reduce Quality
What makes one kit better than another? It often comes down to design and manufacturing care.
Factors That Improve Quality:
- Brand Reputation: Established brands usually test their parts thoroughly.
- Tight Tolerances: Parts that fit exactly reduce friction and wear.
- Complete Installation Hardware: A high-quality kit includes all necessary gaskets and seals.
Factors That Reduce Quality:
- Generic Components: Kits using very cheap, unbranded lifters often fail early.
- Missing Instructions: Poor instructions lead to installation mistakes, which ruin the kit.
- Incompatible Parts: If the lifters are slightly wrong for your specific Hemi year, they will cause engine noise or damage.
User Experience and Use Cases
Why do people buy these kits? The experience changes depending on the goal.
Most users install an MDS delete kit for performance gains. When the MDS is gone, the engine runs on all eight cylinders all the time. This gives better throttle response and more horsepower. Users report a slightly rougher idle in some cases, especially with aggressive cams, but overall, the engine feels stronger.
Another common use case is reliability. The MDS system is known to fail over time, causing rough running. Deleting it fixes this persistent problem forever. If you plan on heavy towing or racing your truck or car, deleting the MDS is a smart upgrade for better engine health under stress.
Frequently Asked Questions (FAQ) About MDS Delete Kits
Q: Will this kit harm my 5.7L Hemi engine?
A: No, when installed correctly, a quality kit improves reliability. It just stops the cylinder deactivation feature from working.
Q: Do I need a special tune after installing the delete kit?
A: Yes, absolutely. You must reprogram the Engine Control Unit (ECU) to tell the computer the MDS is gone. Without a tune, the “Check Engine” light will stay on.
Q: How much horsepower can I expect to gain?
A: Gains vary. If you only replace the lifters, gains are small. If you use a performance camshaft in the kit, you might see 15 to 30 more horsepower.
Q: Is the installation difficult?
A: This is a major engine job. You must remove the cylinder heads. This requires specialized tools and mechanical skill. Most people hire a professional mechanic for installation.
Q: Will my fuel economy get much worse?
A: Yes, slightly. Since the engine always uses eight cylinders, you will likely lose a small amount of highway fuel economy, maybe 1 to 2 miles per gallon.
Q: What years of 5.7L Hemi do these kits fit?
A: Most kits fit the 2006 to 2018 Hemi engines, but always double-check the seller’s description for your exact engine code.
Q: What if I only replace the lifters and not the cam?
A: This is called a “mild delete.” It fixes MDS failure issues but offers fewer performance benefits than a full cam swap.
Q: What is the most common mistake people make when installing this?
A: The most common mistake is incorrect timing when installing the new camshaft or not properly priming the new lifters before startup.
Q: Are the new lifters louder than the stock ones?
A: Quality aftermarket lifters should operate as quietly as stock once the engine oil pressure builds up. Any persistent ticking usually means improper installation or low oil pressure.
Q: Can I remove the MDS solenoid myself without the full kit?
A: You can unplug the solenoid, but the computer will still try to send signals. You need the physical plug or a proper tune to stop error codes.
