How to Use 3.6 Engine 4PCS Camshafts Rocker Arm Kit for 2011-2016 Jeep Grand Cherokee Wrangler, Dodge Challenger Durango Charger, Ram RAM 1500 ProMaster, Chrysler 200 300 3.6L V6 Pentastar: Complete Guide

Step 1: Initial Preparation and Disassembly

This is a major engine service. Begin by disconnecting the battery. Drain the engine coolant and oil. Remove the intake manifold, valve covers, serpentine belt, and crankshaft pulley. You must lock the timing chains in place with specialty tools (like a dual cam lock tool set) before removing the camshafts to prevent the engine from losing timing. Carefully label all electrical connectors and hoses. Having a service manual for your specific vehicle is highly recommended. This is the most labor-intensive part of the job and sets the stage for a successful installation of your new buy 3.6 Pentastar camshaft rocker arm kit.

Step 2: Camshaft, Lifter, and Rocker Arm Removal

With the valve covers off and timing secured, you can now see the valvetrain. Remove the camshaft bearing caps in the correct order (typically marked or outlined in the manual) and lift out the old camshafts. The hydraulic lifters and rocker arms can then be removed from the cylinder head. Inspect the old parts for obvious wear—scored cam lobes, collapsed lifters, and worn rocker arm pivots are common. Keep everything organized.

Step 3: Installation of New Components

This is where the TREXCAR kit comes into play. Liberally lubricate all new components with assembly lube or fresh engine oil. Install the new hydraulic tappets into their bores. Place the new rocker arms onto the lifters. Carefully lower the new TREXCAR camshafts into place, ensuring they are properly seated. Reinstall the bearing caps in the correct order and torque them to specification in a crisscross pattern. This precise installation is what makes a best camshaft kit for 3.6L V6 worth the effort.

Step 4: Timing Reassembly and Final Steps

With the new cams in place, re-time the engine using your locking tools. Reinstall the timing chains, tensioners, and guides. Replace the crankshaft pulley, serpentine belt, and valve covers using a new gasket set. Reinstall the intake manifold and reconnect all hoses and electrical connectors. Refill the engine with fresh oil and coolant. For a smooth first start, we recommend using a high-quality synthetic oil and a new filter.

Step 5: First Start and Break-In Procedure

Before starting, prime the oil system by cranking the engine with the fuel pump fuse removed for 10-15 seconds. Reinstall the fuse and start the engine. It may run roughly for a minute as the lifters bleed down and prime—this is normal. Listen carefully. The infamous tick should be gone. Allow the engine to reach operating temperature while monitoring for leaks. A proper break-in involves varying RPMs (avoid constant idle or cruise) for the first 20-30 minutes to properly seat the new components.

Step 6: Ongoing Maintenance and Care

After the repair, stick to a rigorous oil change schedule with full synthetic oil. The health of the new hydraulic lifters depends on clean oil. Consider using an oil additive designed for lifter noise during the first oil change. Regularly check for any unusual noises. For more detailed maintenance tips after a major service like this, see our guide on post-engine repair care.

Performance & Real-World Testing

Testing Methodology

We installed this TREXCAR kit on a 2014 Jeep Grand Cherokee with 115,000 miles that exhibited a pronounced cold-start tick and a slight loss of power. The installation followed the steps above, and we monitored the vehicle for over 500 miles of mixed city and highway driving. We used a mechanics stethoscope to listen to the valvetrain before and after, and performed basic performance checks.

Performance Metrics

The most immediate and dramatic result was the complete elimination of the cold-start tick. From the first start after installation, the engine was significantly quieter. Throttle response felt sharper, likely due to restored proper valve timing and lift. We observed no change in fuel economy, which remained consistent, indicating the kit restored efficiency without introducing any parasitic loss. The engine idled smoothly at a steady RPM.

Real-World Scenarios

In daily commuting, the difference was night and day. The constant worry about the ticking noise was gone. On a longer highway trip, the engine felt more confident and willing under acceleration. For a vehicle used for towing or hauling, this repair is critical to restoring full engine power and reliability. This real-world performance solidifies the argument that this 3.6 Pentastar cam kit is worth buying for affected vehicles.

Claims vs. Reality

TREXCAR claims direct OEM fit and function. In our testing, this claim held true. Every component fit perfectly into place with no clearance issues. The claim of solving the ticking noise was 100% accurate in our test case. The kit performed exactly as a complete valvetrain refresh should. There were no surprises or hidden shortcomings, which is exactly what you want when you decide to buy 3.6 Pentastar camshaft rocker arm kit.

Pros and Cons

What We Loved (Pros)

• Complete Solution: It includes every major wear component (cams, lifters, rockers), so you only need to buy gaskets and fluids. This simplifies sourcing and ensures part compatibility.
• OEM-Spec Fitment: Everything dropped right in place on our test vehicle. No modification, shimming, or adjustment was needed beyond standard procedures.
• Effective Noise Elimination: It completely resolved the Pentastar tick, resulting in a quiet, smooth-running engine.
• Cost-Effective vs. OEM: Purchasing all these components individually from a dealership would cost significantly more, making this kit a strong value proposition.
• Good Build Quality: The machining on the camshafts and the finish on all components appeared to be of high quality, inspiring confidence in its longevity.

What Could Be Improved (Cons)

• No Gaskets Included: This is the most notable omission. You must purchase a separate upper engine gasket kit, which adds to the total project cost and requires extra planning.
• Labor-Intensive Installation: This isn’t a fault of the product, but potential buyers must understand this is not a simple “under-the-hood” swap. It requires mechanical skill, specialty tools, and a significant time commitment.
• Limited Long-Term Data: While our initial testing is excellent, the product’s long-term durability (e.g., 50,000+ miles) can’t be verified in a short review period. However, the design and materials suggest it should last.

Expert Tips for Maximum Value

Tip #1: Invest in the Right Tools

Don’t attempt this job without a quality torque wrench, a set of cam locking tools specific to the 3.6L Pentastar, and a good set of sockets and extensions. The right tools prevent costly mistakes.

Tip #2: Replace ALL Components in the Kit

Even if only one rocker seems bad, replace them all. The wear is often even across the engine, and replacing everything ensures balanced performance and prevents a return trip into the engine bay soon after.

Tip #3: Use a High-Quality Gasket Set

Pair this excellent hardware with equally good seals. A complete upper engine gasket set from a reputable brand is a mandatory companion purchase to prevent oil leaks.

Tip #4: Take Photos and Label Everything

During disassembly, use your phone to take pictures of hose routing, connector locations, and bolt arrangements. Use masking tape and a marker to label things. This makes reassembly far less stressful.

Tip #5: Perform an Oil Change Immediately After Break-In

After the first 50-100 miles of driving, change the oil and filter again. This removes any initial wear particles from the new components mating together, promoting long-term health.

Common Mistakes to Avoid

1. Mistake: Not locking the timing chains before removing camshafts. → Solution: This is the cardinal rule. Always use the proper cam lock tools. Skipping this will cause the engine to lose timing, leading to bent valves and catastrophic damage.
2. Mistake: Not torquing cam bearing caps in the correct order and to specification. → Solution: Follow the factory service manual sequence exactly. Use a calibrated inch-pound torque wrench for the final torque values.
3. Mistake: Installing components dry. → Solution: Liberally coat all new cam lobes, lifter faces, and rocker arm pivots with assembly lube or fresh engine oil during installation.
4. Mistake: Reusing old gaskets and seals. → Solution: Always use new gaskets. The cost is minimal compared to the labor of fixing an oil leak later.
5. Mistake: Not priming the oil system before the first start. → Solution: Always crank the engine with the fuel disabled to build oil pressure and fill the new lifters before combustion starts.
