Many owners assume that any replacement part carrying the right part number will perform just like the original equipment. This assumption often leads to premature engine failure because subtle differences in internal machining make a massive difference under high heat.
Selecting the Best Aftermarket Lifters for 5.7 Hemi requires looking past the part number and focusing on durability and compatibility. I put together these insights to help you choose hardware that keeps your engine running smoothly for years to come.
Key Takeaways
- Decide if you truly need to retain the Multi-Displacement System or if a permanent delete kit is better for your driving style.
- Check that your chosen lifters match the specific production year and model of your engine to avoid oil pressure issues.
- Prioritize high-quality metallurgy to handle the heavy valve spring pressure common in modern performance setups.
- Ensure your kit includes the necessary hardware like trays or plugs if you choose to move away from factory systems.
- Consider purchasing a full camshaft and lifter kit if your existing components show any signs of metal shavings or wear.

Frequently Asked Questions
Why do 5.7 Hemi lifters fail so often?
The primary culprit is often the MDS system or simple heat soak that degrades the internal check valves. When the plastic lifter trays wear out, the lifter rotates, causing the roller to grind against the cam lobe instead of rolling smoothly.
Should I delete the MDS when replacing lifters?
Many enthusiasts choose to delete the MDS because it removes the complex hardware that often causes lifter noise and failure. By switching to a non-MDS camshaft and lifter set, you increase engine reliability and simplify your valvetrain architecture.
How do I know if my lifters are failing?
Listen for a distinct ticking or tapping sound that increases in frequency as engine RPM rises. If you notice a misfire code or a rough idle, pull the valve covers to check for excessive lash in the rocker arms.
Do I need to replace the camshaft when I change lifters?
If your current lifters have already started to score the cam lobes, you must replace the camshaft. Reusing a damaged cam with new lifters will destroy your new components in a matter of minutes.
Is it necessary to soak new lifters in oil before installation?
Yes, you should soak them in clean engine oil for several hours before putting them into the block. This helps remove trapped air and ensures the hydraulic plunger is primed for the initial startup, which prevents scuffing.
