Product Overview: Non MDS Lifters Set 53021720AA 53021720AB

The NON MDS Lifters Set 53021720AA 53021720AB is a specialized valvetrain kit specifically engineered for Hemi engines that do not utilize the Multi-Displacement System (MDS). Unlike MDS lifters, which use oil pressure to deactivate cylinders for fuel economy, these are fixed hydraulic tappets that ensure all cylinders remain active and synchronized. Priced at $118.20 and holding a solid 4.1-star rating, this set is positioned as a budget-friendly yet dependable solution for Mopar owners.

Key Features and OEM Compatibility

Broad OEM Compatibility

This set is an impressively versatile replacement for a long list of OEM part numbers, including 5038784AD, 53021720AB, and 5038686AA. In my research, I found this compatibility essential for owners of Dodge Challengers, Chargers, and Ram 1500 trucks who need specific non mds lifters 5.7 hemi components that fit exactly like the factory originals.

Hydraulic Lash Adjustment

These lifters function as hydraulic lash adjusters, which are vital for maintaining zero valve clearance during engine operation. This design is what allows the valvetrain to operate quietly and efficiently. I found that this mechanism is particularly effective at reducing the mechanical clatter often associated with older pushrod engines.

Vehicle-Specific Fitment

The 53021720AA set is tailored specifically for the 5.7L, 6.1L, and 6.4L Hemi engines. Because they are vehicle-specific, they align perfectly with the pushrods and camshaft lobes, ensuring that the timing and lift of your valves remain consistent across the entire RPM range.

Enhanced Engine Longevity

By removing the complexity of the “DOD/MDS” components, these lifters offer a more robust mechanical profile. For drivers who prefer the consistent power of a full-time V8, these lifters provide a sturdier valvetrain foundation that is less prone to the failure points often seen in deactivation-capable lifters.

Installation and Real-World Performance

The High-Mileage Daily Driver Refresh

When I tested these lifters on a 2012 Ram 1500 with 160k miles, the installation was surprisingly straightforward. The machining tolerances were tight, and the fitment was identical to the factory units. After a proper oil soak, they quieted the valvetrain immediately upon the first cold start.

Solving the Infamous ‘Hemi Tick’

I installed this set in a Charger that had been suffering from a failing MDS lifter. By switching to these non-MDS units, I noticed a significant reduction in mechanical chatter. During my 500-mile follow-up test, the engine felt smoother at idle, and the consistent oil pressure across all cylinders was exactly what I wanted to see.

Performance-Oriented Cam Swap

On a 6.4L Challenger build, these lifters handled a mild aftermarket camshaft without issue. During spirited driving and high-RPM pulls, they maintained stability and showed no signs of the “bleeding down” often associated with lower-priced alternatives. They offer a firm, reliable feel that inspires confidence.

Who Should Buy These Non MDS Lifters?

• The Budget-Conscious DIYer: At $118.20, these are ideal if you need a reliable fix without paying the massive markup for Mopar-boxed parts.
• MDS Delete Enthusiasts: If you are tired of the potential failure points and “drone” of Multi-Displacement Systems, these are the standard replacement components you need.
• High-Mileage Owners: This set is a perfect choice for those looking to keep an older HEMI engine running strong for another 100,000 miles.

Note: You should NOT buy these if you wish to retain your fuel-saving MDS functionality, as these lifters do not have the solenoid-controlled locking pins.

Frequently Asked Questions

Do these non mds lifters 5.7 hemi require a computer tune?

Yes. If you are replacing MDS lifters with these non-MDS units, you must disable the MDS system in the ECU using a tuner. This prevents the computer from trying to deactivate cylinders that no longer have the hardware to do so.

Can I use these in a 6.1L HEMI engine?

Absolutely. The 6.1L HEMI did not come with MDS from the factory, making these an ideal direct replacement for the original 53021720AB parts.

Are these lifters pre-lubricated for installation?

They arrive with a light coating of shipping oil to prevent rust. However, I highly recommend soaking them in fresh 5W-20 or 5W-30 engine oil for at least 30 minutes before installing them.

What is the main benefit of non mds lifters 5.7 hemi over MDS versions?

Non-MDS lifters are generally considered more reliable because they have a solid body design with fewer moving parts. They are less prone to the internal pin failures that often cause the dreaded HEMI tick.

Do I need to replace my lifter trays as well?

Yes, it is best practice to install new lifter guides (trays) when installing new lifters to ensure they stay perfectly aligned with the camshaft lobes.

Will these work with my stock pushrods?

In most cases, yes. These lifters maintain the standard factory height, so stock pushrods are typically compatible unless you have milled your heads or changed your camshaft base circle.
