The Ultimate Buying Guide: Upgrading Your 5.7 Hemi
The 5.7 Hemi engine is a beast on the road. However, many owners dislike the Multi-Displacement System (MDS). This system shuts down cylinders to save fuel. It often causes vibration, oil consumption, and annoying ticking sounds. A MDS delete kit removes this system and improves engine performance. Use this guide to choose the right kit for your truck or car.
Key Features to Look For
A complete kit should include everything you need for the swap. Look for high-quality hydraulic lifters. These are the most important parts of the kit. Ensure the kit includes new head gaskets and head bolts. You also need a camshaft designed for a non-MDS engine. Many kits include pushrods that match the new cam. Check if the kit includes a tuner or programmer. You will need a tune to tell the computer that the MDS system is gone.
Important Materials
Durability depends on the materials used. Choose lifters made from hardened steel. High-quality steel prevents the ticking noise common in older Hemi engines. Look for gaskets made from multi-layer steel (MLS). These provide the best seal for your engine. Avoid cheap plastic or rubber parts. Your engine creates high heat, so only use professional-grade metal components.
Factors That Improve or Reduce Quality
The quality of your kit changes based on the manufacturer. Reputable brands test their parts for thousands of miles. Kits that include “drop-in” parts make installation much easier. Poor quality kits often use generic lifters that fail quickly. This leads to engine damage. Always buy from companies that specialize in Mopar engines. A good kit fits perfectly without needing extra modifications.
User Experience and Use Cases
Most users install these kits to fix the “Hemi Tick.” After the install, the engine runs smoother. You will feel more power when accelerating. This is great for people who tow trailers or drive in mountainous areas. You might see a slight drop in fuel economy. However, most owners agree that the reliability gain is worth it. This upgrade is perfect for high-mileage engines that need a refresh.
Frequently Asked Questions
Q: Do I need a professional to install the kit?
A: Yes. This process involves removing the cylinder heads and camshaft. It requires advanced mechanical skills and special tools.
Q: Will this void my warranty?
A: Yes. Installing an aftermarket delete kit will likely void your factory powertrain warranty.
Q: Is a custom tune mandatory?
A: Yes. Your truck’s computer expects the MDS system to work. Without a tune, the engine will throw error codes and run poorly.
Q: How long does the installation take?
A: It usually takes an experienced mechanic 10 to 15 hours. Plan for several days if you are doing it in your garage.
Q: Will my engine sound different?
A: Many users report a deeper, more aggressive exhaust note. The annoying “drone” sound often disappears.
Q: Does this kit improve horsepower?
A: Yes. Removing the MDS system and adding a performance camshaft usually adds 20 to 40 horsepower.
Q: Can I keep my old camshaft?
A: No. MDS engines have different cam lobes than non-MDS engines. You must replace the cam for the engine to run correctly.
Q: Are there any oil requirements after the install?
A: Your engine may run cooler and cleaner. Use high-quality synthetic oil to keep the new lifters in top shape.
Q: Will my check engine light stay on?
A: Not if you use a proper tuner. A custom tune will disable the MDS sensors so the light stays off.
Q: Is this upgrade worth the cost?
A: For most Hemi owners, yes. It prevents future lifter failure and makes the engine much more reliable for the long haul.
