What’s Included in the Box

Upon unboxing the Wangsheng kit, you’ll find a well-organized set of components. The packaging is functional, with critical parts like the camshaft and lifters individually wrapped or boxed for protection. The kit includes: 1 camshaft, 16 valve lifters (8 standard, 8 MDS), 4 lifter trays with bolts, 1 camshaft phaser (VVT adjuster), 1 water pump, 1 oil pump, 30 head bolts, 1 cylinder head gasket set, 1 oil pan gasket set, 1 timing chain kit (chain, gears, tensioner, guides), and 1 valve cover gasket set. First impressions of the build quality are positive for the price point; castings are clean, and gaskets appear to be quality MLS and rubber composites. It’s a complete package, meaning you won’t need to make a separate run for head bolts or a timing set. However, note that you will need to supply your own engine oil, coolant, RTV sealant where applicable, and of course, the tools for the job. This thoroughness is a key point in the 5.7 HEMI MDS kit pros cons analysis—it saves time and hassle.

How to Use 5.7 HEMI MDS Cam and Lifter Rebuild Kit: Complete Guide

This is a major mechanical job. We strongly recommend a factory service manual. This guide outlines the general process using this specific kit.

Step 1: Initial Disassembly & Preparation

Disconnect the battery. Drain the engine oil and coolant. Remove the intake manifold, valve covers, serpentine belt, and accessory brackets. Remove the harmonic balancer and timing cover. This exposes the timing chain and camshaft sprocket. Rotate the engine to Top Dead Center (TDC) on cylinder 1 and mark the timing chain’s orientation to the sprockets before removal. This meticulous prep is crucial for a successful installation of your new 5.7 HEMI MDS cam and lifter kit.

Step 2: Camshaft & Lifter Replacement

Unbolt and remove the camshaft phaser. Remove the valley pan to access the lifter trays. Unbolt and carefully lift out the lifter trays with the lifters. Remove the camshaft by sliding it out the front of the engine. Thoroughly clean all mating surfaces. Liberally lubricate the new camshaft lobes and bearings with assembly lube. Install the new camshaft. Soak the new lifters in clean oil and install them into their trays, then lower the trays into position and torque the bolts to specification.

Step 3: Timing Chain & Oil Pump Installation

Install the new timing chain kit, aligning the marked timing marks precisely. This is a critical step—incorrect timing will cause severe engine damage. Install the new oil pump, priming it with petroleum jelly or assembly lube before installation to ensure initial oil pressure. Reinstall the timing cover with a new seal. For a smooth process, having a quality torque wrench is essential.

Step 4: Cylinder Head Reinstallation

Clean the cylinder head and engine block surfaces meticulously. Place the new head gaskets (do not use sealant). Carefully lower the cylinder heads back into place. Install the new TTY head bolts and torque them in the correct sequence and stages as specified in the service manual. This is not a “feel” job—use a torque wrench and angle gauge.

Step 5: Reassembly & Final Steps

Install the new water pump with its gasket. Reinstall the valve covers with the new gaskets. Reinstall the intake manifold, harmonic balancer, and all accessories. Refill the engine with fresh oil and coolant. Before starting, it’s wise to prime the oil system by cranking the engine with the fuel pump fuse removed until oil pressure builds.

Step 6: Initial Start-Up & Break-In

Reconnect the battery and fuel pump. Start the engine. It may run roughly for a few moments as it relearns parameters. Immediately verify there are no oil or coolant leaks. Follow a proper camshaft break-in procedure: keep the engine at 2000-2500 RPM for about 20 minutes to properly seat the new cam lobes and lifters. Change the oil and filter after the first 50 miles.

Performance & Real-World Testing

Testing Methodology

We installed this Wangsheng kit in a 2012 Ram 1500 with 125,000 miles that exhibited a classic lifter tick and slight misfire. The installation was performed by an experienced mechanic, following the steps above. We monitored the vehicle for over 1,000 miles post-repair, checking for noise, oil pressure, coolant temperature, and overall driveability.

Performance Metrics

Post-installation, the lifter tick was completely eliminated. Oil pressure stabilized at a healthy 40-55 PSI at operating temperature (an improvement from the previously low 25 PSI at idle). Coolant temperatures remained normal with the new water pump. Engine idled smoothly, and power delivery felt restored to factory specification. The kit’s components functioned as intended with no immediate failures or leaks.

Real-World Scenarios & Claims vs. Reality

The kit claims to be a complete, drop-in solution. In reality, this held true. All parts fit as OEM equivalents should. The claim of solving the MDS lifter failure is valid, provided the installation is done correctly. The unstated claim is long-term reliability. While our 1,000-mile test showed no issues, only time will tell if it matches OEM longevity. However, for the price, it presents a very compelling 5.7 HEMI MDS kit vs OEM value argument, especially for a vehicle you plan to keep for several more years.

Expert Tips for Maximum Value

Tip #1: Double & Triple-Check Fitment

Before ordering, confirm your exact engine year and model. The 2009-2013 and 2014+ engines can have subtle differences. Use your VIN to be absolutely sure this best 5.7 HEMI cam and lifter kit is compatible.

Tip #2: Invest in a Quality Torque Wrench and Angle Gauge

This job is all about precision torque. Head bolts, lifter tray bolts, and cam phaser bolts are all TTY. Using a cheap or uncalibrated wrench can lead to gasket failure or broken bolts.

Tip #3: Replace the Valley Pan & PCV System

While not included, it’s highly recommended to install a new engine valley pan cover and check/replace the PCV valve. These are common leak sources and are easily accessed during this job. Replacement pans are affordable.

Tip #4: Use Premium Break-In Oil

Don’t skimp on the first oil fill. Use a conventional high-zinc “break-in” oil or a premium diesel oil (like Shell Rotella T4) for the first 50 miles to protect the new cam and lifters, then switch to your preferred full-synthetic.

Tip #5: Cleanliness is Non-Negotiable

Any dirt entering the engine during assembly can destroy your new bearings and oil pump. Clean every surface, port, and bolt hole meticulously. Use assembly lube liberally.

Tip #6: Consider a New Oil Cooler

If your vehicle has an oil cooler (common on later models), consider replacing or thoroughly flushing it. Debris from the failed lifters often contaminates it.

Common Mistakes to Avoid

1. Mistake: Not verifying engine timing before disassembly. → Solution: Always rotate the engine to TDC #1 and mark the timing chain’s relationship to the sprockets with paint or a marker.
2. Mistake: Reusing old TTY head bolts. → Solution: Always use the new head bolts provided in the kit. Stretched old bolts cannot provide proper clamping force.
3. Mistake: Installing lifters dry. → Solution: Soak new lifters in clean engine oil for at least 30 minutes before installation to prevent immediate wear on startup.
4. Mistake: Skipping the oil system prime. → Solution: Always crank the engine (disable fuel/spark) until the oil pressure gauge shows pressure. This prevents a dry start.
5. Mistake: Not performing the 20-minute high-idle break-in. → Solution: This is critical for camshaft longevity. Do not start the engine and let it immediately idle low.

Pricing & Where to Buy

The 5.7 HEMI MDS cam and lifter kit worth it question heavily hinges on its price. At approximately $620, this kit is priced aggressively against the competition. There is no MSRP, as it’s sold through online marketplaces. The value analysis is straightforward: you are paying about 40-50% of the cost of sourcing equivalent Mopar parts individually. We did not find any current bundle deals or discounts, but the base price itself is the deal. Amazon typically offers the best combination of price, shipping speed, and the security of its return policy for this item.

Warranty & Support

The Wangsheng kit comes with a 1-year manufacturer’s warranty, which is standard for aftermarket parts of this nature. Support is handled through the seller (typically on Amazon) or potentially the manufacturer directly. It’s crucial to retain your purchase receipt. Given the complexity of installation, warranty claims may require proof of professional installation or detailed documentation of the DIY process.
