Helpful Comparison Insights

When you’re looking at best camshaft options for 5.7 Hemi performance enhancements, the biggest decision usually comes down to MDS or Non-MDS, and whether you want a full kit or just the cam.

First off, MDS vs. Non-MDS is critical. If your Hemi has MDS (Multi-Displacement System), which most modern 5.7 Hemis do, it allows your engine to run on four cylinders under light load for fuel economy. However, it’s also a common source of ticking noises and lifter failures. Many of the kits reviewed, like the Upgrade MDS 5.7 HEMI Lifters Camshaft Kit (Product 1) or the GELUOXI MDS Lifters Camshaft Kit (Product 6), are designed to replace MDS components with new, often improved, MDS-compatible parts. These are great if you want to keep your fuel economy benefits and simply resolve reliability issues.

On the other hand, if you’re chasing maximum performance and reliability, or simply hate that MDS activation feel, a Non-MDS conversion is often preferred. Kits like the SUSUCAR 5.7 Hemi Non MDS Lifter Cam (Product 2) and the incredibly comprehensive Non MDS 5.7 HEMI Lifters Camshaft Oil Pan Kit (Product 4) provide everything needed for this conversion, including the crucial block-off plugs. Be aware that deleting MDS requires a PCM tune to prevent check engine lights and ensure proper engine operation, so factor that into your budget and planning. These kits offer consistent V8 power all the time, which many enthusiasts prefer.

Another major differentiator is the completeness of the kit. Some options, like the standalone 53022263AF MDS Camshaft Replacement (Product 3) or the GELUOXI MDS 5.7 HEMI Engine Camshaft (Product 5), are just the camshaft itself. These are excellent if you only need the cam and have existing lifters and gaskets in good condition, or if you plan to mix and match other aftermarket components. However, for a full rebuild or to address multiple issues at once, full kits provide incredible value and convenience. Products like the Non MDS 5.7 HEMI Lifters Camshaft Oil Pan Kit (Product 4) even include timing chains and oil pans, while the 5.7L Hemi MDS Camshaft Lifter Kit (Product 7) is unique for offering both MDS and Non-MDS lifters, giving you options.

Year and vehicle compatibility are paramount. Some kits are highly specific, like the Non MDS 5.7 HEMI Lifters Camshaft Cam Kit (Product 8) for 2005-2008 models, or the MDS 5.7 Hemi Lifters Camshaft Kit (Product 10) for Chrysler 300s. Others, like the GELUOXI kits (Products 5 & 6), boast broader compatibility across various car and SUV Hemi platforms. Always double-check your specific year and model against the product’s fitment list.

Finally, consider your performance goals. Most of these kits are focused on restoring or improving reliability and stock performance, especially those with MDS. While a non-MDS conversion itself can feel like a performance enhancement due to consistent power delivery, if you’re looking for a cam that significantly boosts horsepower and torque with an aggressive idle, you’ll generally need to look at dedicated aftermarket performance camshafts (which weren’t the focus of these specific OEM-replacement-style kits). However, some non-MDS kits, by getting rid of the factory restrictions, can lay a solid foundation for future power-adding modifications.

Final Verdict

Deciding on the best camshaft options for your 5.7 Hemi performance enhancements really boils down to your primary goal.

If your Hemi is experiencing that dreaded MDS tick or lifter failure, and you want a reliable, factory-spec repair that keeps your MDS system for fuel economy, then the Upgrade MDS 5.7 HEMI Lifters Camshaft Kit (Product 1) or the GELUOXI MDS 5.7 HEMI Lifters Camshaft Kit w/Head Gasket (Product 6) are excellent, comprehensive choices. They offer a complete package to get your engine running quietly and smoothly again.

For those who are tired of the MDS system and want to eliminate it for consistent V8 power and enhanced reliability, the SUSUCAR 5.7 Hemi Non MDS Lifter Cam (Product 2) is a strong contender that retains VVT. However, if you’re undertaking a full engine overhaul and want to replace nearly everything related to the valve train and timing while going Non-MDS, the Non MDS 5.7 HEMI Lifters Camshaft Oil Pan Kit w/Timing (Product 4) is simply unmatched in its completeness. Just remember, an MDS delete will require a PCM tune.

If you have an older 5.7 Hemi (2005-2008), the Non MDS 5.7 HEMI Lifters Camshaft Cam Kit (Product 8) is specifically tailored for your needs with its comprehensive parts list, including crucial block-off plugs.

Ultimately, whether you’re fixing a problem, simplifying your engine, or just refreshing its components, choosing from these 5.7 Hemi camshaft options means carefully matching the kit’s contents and compatibility to your vehicle and your mechanical ambitions. Always verify your year, model, and engine code before making your final decision.

Comprehensive FAQ Section

Q1: What exactly does a camshaft do in my 5.7 Hemi engine?
A camshaft controls the opening and closing of your engine’s valves. It’s crucial for engine breathing – dictating when the air/fuel mixture enters the cylinders and when exhaust gases exit. The profile of the camshaft’s lobes directly affects your engine’s power, torque, and overall characteristics, making it a key component for 5.7 Hemi performance enhancements.

Q2: What’s the difference between an MDS and a Non-MDS camshaft for the 5.7 Hemi?
MDS (Multi-Displacement System) camshafts are designed to work with the engine’s cylinder deactivation feature, allowing four cylinders to shut off under light loads for better fuel economy. Non-MDS camshafts (and associated lifters) are designed for engines that run on all eight cylinders all the time. If you convert to non-MDS, you’ll typically gain consistent V8 power and often improve reliability, but you’ll lose the fuel-saving feature and need a PCM tune. Many of the best camshaft options for 5.7 Hemi address this directly.

Q3: Do I need to replace my lifters when replacing my 5.7 Hemi camshaft?
Yes, it’s highly recommended to replace your lifters whenever you replace the camshaft. New cams and old lifters often don’t “play well” together, leading to premature wear on both components. Many of the reviewed 5.7 Hemi camshaft options come as complete kits, including new lifters and sometimes even gaskets, simplifying the process and ensuring proper function.

Q4: Will I need an engine tune after installing a new camshaft in my 5.7 Hemi?
If you’re replacing your camshaft with a direct OEM-spec replacement that maintains your current engine configuration (e.g., MDS to MDS), a tune might not be strictly required but is often beneficial for optimal performance. However, if you’re performing an MDS delete or installing an aftermarket performance camshaft for 5.7 Hemi performance enhancements with a different lobe profile, a PCM tune is absolutely essential to prevent check engine lights, ensure proper fuel mapping, and get the most out of your new cam.

Q5: How difficult is it to install a new camshaft in a 5.7 Hemi? Can I do it myself?
Installing a camshaft in a 5.7 Hemi is a significant undertaking. It involves disassembling the front of the engine, removing cylinder heads (often for lifter access), and dealing with various gaskets and seals. While a mechanically inclined DIYer with proper tools and a shop manual can attempt it, it’s a complex job. Many recommend professional installation, especially for MDS delete kits, to ensure everything is reassembled correctly and prevent costly mistakes.

Q6: Besides camshafts and lifters, what other components should I consider replacing during a 5.7 Hemi performance enhancement?
When replacing 5.7 Hemi camshaft options, it’s wise to consider related components. At a minimum, you’ll need new head gaskets, intake manifold gaskets, exhaust manifold gaskets, valve cover gaskets, and a new timing cover gasket. Many of the comprehensive kits reviewed (like Products 2, 4, 8, 9, 10) include these. Additionally, inspecting or replacing your timing chain, oil pump, pushrods, and valve springs (especially with performance cams) is often a good idea to ensure overall engine reliability and longevity.
