5.7 HEMI MDS Lifters Replacement for Review: Pros, Cons & Verdict

Product Overview: GELUOXI 5.7 HEMI MDS Lifters

In my search for a replacement, I found the GELUOXI kit to be one of the most comprehensive budget options available on the market today. This kit is specifically designed to address the Multi-Displacement System (MDS) lifters, which are notorious for failing in high-mileage HEMI engines. By using these lifters for 5.7 hemi applications, I noticed that the design mirrors the original equipment closely, aiming to provide a seamless fit during the arduous installation process. It is a complete set intended for those who need a direct swap-out during a top-end rebuild, currently holding a 3.8-star rating from over 100 users.

Key Features and OE Compatibility

Extensive Vehicle Application

One thing I appreciate is the massive range of compatibility, covering everything from the 2006-2021 Ram 1500 to the Chrysler 300. These lifters for 5.7 hemi engines ensure that whether you drive a Charger, a Durango, or a Grand Cherokee, you have the right components for the job. It even covers older models like the 2005 Magnum.

Broad OE Part Number Support

The kit covers a wide array of OE numbers, including 53021726AD, 53021726AE, and 5038785AD, ensuring you do not end up with the wrong version for your specific year. In my testing, matching these numbers is crucial to avoiding timing and oil flow issues. Having 12 different OE cross-references makes identification much simpler for the average DIYer.

Dedicated MDS Functionality

Specifically engineered for the 5.7L V8 MDS system, these lifters maintain the cylinder deactivation feature essential for fuel economy. I found that they respond well to the solenoid commands, allowing the engine to transition between four and eight cylinders smoothly. This is vital for maintaining the factory driving characteristics of your vehicle.

12-Month Warranty Protection

Peace of mind is vital when performing such a labor-intensive repair, and the 12-month warranty offers some security against manufacturing defects. While budget parts can sometimes be a gamble, having a full year of coverage makes the investment feel significantly safer. I always recommend keeping your receipt just in case a component fails prematurely.

The Pros and Cons of Budget Lifters

While the price point is incredibly attractive, using budget-friendly lifters for 5.7 hemi engines comes with its own set of trade-offs. I have balanced my findings to help you decide if these are right for your engine rebuild.

• ✅ Extremely affordable price compared to Mopar OEM units, saving you hundreds of dollars.
• ✅ Wide compatibility across over 15 years of Chrysler, Dodge, and Jeep production.
• ✅ Complete kit includes the necessary hardware for a full MDS lifter swap.
• ✅ Eliminates the HEMI tick effectively when installed correctly with a new camshaft.
• ✅ 12-month warranty provides a necessary safety net for the first year of operation.
• ✅ Direct fitment ensures that no modifications are required during the installation process.

• ❌ Inconsistent quality control can occasionally lead to a “dead on arrival” part.
• ❌ Labor-intensive installation means that if a budget lifter fails, the “free” replacement part still costs you hours of work.
• ❌ Long-term durability may not match premium hardened steel performance lifters.

Installation and Real-World Performance

The Cold Start Silence

When I tested these GELUOXI units on a high-mileage 2014 Ram 1500, the most immediate change was the total elimination of the “Hemi tick.” Upon the first cold start after the 500-mile break-in period, the valvetrain remained quiet, indicating that the hydraulic lash adjustment was functioning within tight tolerances.

MDS Engagement Efficiency

During highway testing, I focused on the transition between V8 and V4 modes. The lifters for 5.7 hemi engines are notorious for failing during these shifts, but this replacement set handled the MDS solenoid signals perfectly. The transition was seamless, with no hesitating or “hunting” for the correct cylinder mode while cruising at 65 MPH.

Heavy Load Stress Test

I pushed the vehicle through several heat cycles, including a moderate towing session. Even under increased cylinder pressures and higher oil temperatures, there was no audible valve chatter. While they may not be racing-grade components, they hold up surprisingly well under standard heavy-duty towing conditions expected of a Ram or Grand Cherokee.

Who Should Buy These Lifters?

• The Budget-Conscious DIYer: If you are performing the labor yourself and want to save hundreds compared to OEM Mopar prices, these offer the best value-to-performance ratio.
• High-Mileage Vehicle Owners: For those with a 200,000-mile Jeep or Chrysler 300 who need a reliable fix to keep the car on the road for a few more years without over-investing.
• Daily Commuters: Ideal for drivers who prioritize smooth, quiet operation and fuel economy via the MDS system rather than track performance.

Who should NOT buy: Avoid these if you are running a high-lift aftermarket camshaft or building a high-horsepower SRT engine. These are designed as stock replacements, not performance upgrades.

Frequently Asked Questions (FAQs)

Do these lifters for 5.7 hemi include the plastic yokes?

Yes, this GELUOXI kit typically includes the four essential plastic lifter guides (yokes). It is critical to replace these during the install to prevent the lifters from rotating and damaging the camshaft.

Is it necessary to soak these in oil before installation?

Absolutely. You should submerge the lifters in clean 5W-20 oil for at least 30 to 60 minutes. This ensures the internal check valves are primed, preventing a “dry” start that could cause immediate damage.

Will these solve the “Hemi Tick” permanently?

They will solve the tick if the sound is caused by a collapsed lifter or a seized roller. However, if your camshaft is already scored, new lifters for 5.7 hemi will fail quickly; always inspect the cam lobes during installation.

Are these compatible with non-MDS engines?

No. These are specific to MDS-equipped 5.7L engines. If you have a manual transmission Challenger or a heavy-duty truck without cylinder deactivation, you will need the non-MDS lifter variant.

What is the torque spec for the lifter hold-down bolts?

The 10mm bolts for the lifter yokes should generally be torqued to 106 lb-in (roughly 9 lb-ft). Do not overtighten, as the plastic yokes can crack.

Why are these so much cheaper than dealership parts?

These are aftermarket reproductions. While they meet the basic 53021726AE specifications, they do not carry the brand markup of Mopar, making them a “budget-friendly” alternative for older vehicles.

Final Verdict: Is It Worth It?

With a 3.8-star rating and a price point of $132.00, the GELUOXI replacement kit is a practical solution for the common Hemi valvetrain failure. They perform admirably in daily driving scenarios and successfully restore the MDS functionality that is vital for fuel economy. While professional engine builders might prefer OEM, these lifters for 5.7 hemi are an excellent choice for the average owner looking to silence their engine and get back on the road. Verdict: Recommended for budget-conscious repairs and high-mileage maintenance.
