Review MOPAR Genuine Quick Connect Retainer Kit 5139084aa fits 2010

The **Mopar 05139084AA Connect Retainer Kit (Part Number: 5139084AA)** is a precision-engineered aftermarket component designed to enhance the performance, reliability, and longevity of modern Chrysler, Dodge, Jeep, and Ram vehicles equipped with the **2.4L and 3.6L Pentastar engines**, as well as the **3.0L EcoDiesel** and **3.6L MultiAir engines**. This high-quality retainer kit is specifically crafted to address common issues associated with the **connect rod bolts** in these engines, which can lead to catastrophic failure if not properly maintained. The kit includes a set of **new, high-strength connect retainers**, along with **Mopar s proprietary torque specifications and installation instructions**, ensuring a secure and long-lasting fit. These retainers are engineered to prevent bolt loosening, stripping, or breakage under high-stress conditions, such as during aggressive driving, towing, or heavy loads, where the engine s internal forces are at their peak. Made from **heat-treated steel**, the retainers are designed to withstand extreme temperatures and mechanical stress, providing superior durability compared to standard fasteners. The kit also includes **Mopar s signature blue-tinted retainers**, which are easily identifiable for quick inspection during maintenance checks, helping mechanics and DIY enthusiasts verify proper installation and torque levels. Whether you're restoring an older vehicle, upgrading a performance build, or simply ensuring long-term engine health, this retainer kit is a critical component for maintaining the structural integrity of the engine s crankshaft and connecting rods. Mopar s commitment to quality and compatibility ensures that this kit seamlessly integrates with the factory engine design, offering peace of mind for drivers who demand reliability and performance from their vehicles.

The **Mopar 05139084AA Connect Retainer Kit** is designed to replace the retainer assembly on certain Chrysler, Dodge, and Jeep vehicles, particularly those with the 4.7L, 5.7L, and 6.1L Pentastar engines. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

---

### **Pros of the Mopar 05139084AA Connect Retainer Kit**

1. **OEM Quality and Fitment**

The kit is manufactured by Mopar, the official equipment manufacturer (OEM) for Chrysler, Dodge, and Jeep. This ensures a precise fit and compatibility with the vehicle s original design, reducing the risk of misalignment or improper installation. OEM parts are often built to the same standards as factory components, which can improve reliability and longevity.

2. **Direct Replacement for Common Failures**

The retainer assembly in question is known to fail in certain applications, particularly in vehicles with high-mileage engines or those experiencing excessive vibration. The kit replaces a worn or broken retainer, which can prevent further damage to the engine s valve train or timing components. This can be a cost-effective solution compared to more extensive repairs if the issue is isolated to the retainer.

3. **Ease of Installation**

The kit is designed as a direct replacement, meaning it should be relatively straightforward to install for a mechanically inclined DIYer or a professional mechanic. The parts are typically pre-assembled or clearly labeled, reducing the complexity of the repair process. Installation often requires basic tools and may not necessitate specialized equipment.

4. **Cost-Effective Compared to Engine Overhaul**

Replacing just the retainer kit is significantly cheaper than a full engine rebuild or replacement. For example, if the retainer failure is causing misfires, excessive oil consumption, or timing issues, addressing it early can save thousands of dollars in potential engine damage. The cost of the kit itself is a fraction of the expense of more extensive repairs.

5. **Warranty Coverage**

Mopar parts often come with a warranty, typically ranging from 12 to 60 months, depending on the vehicle s age and mileage. This provides peace of mind in case the part fails prematurely due to a manufacturing defect. The warranty can also cover labor in some cases, depending on the retailer or dealership.

6. **Compatibility with Aftermarket Parts**

If you ve already installed aftermarket components (e.g., performance camshafts, lifters, or retainers), this kit may serve as a compatible upgrade or replacement. Mopar s parts are designed to integrate well with both OEM and aftermarket systems, provided the specifications align.

7. **Prevents Catastrophic Engine Damage**

In some cases, a failed retainer can cause valves to float or timing chain issues, leading to severe engine damage. Replacing the retainer kit proactively can prevent such scenarios, extending the life of the engine and avoiding costly repairs.

### **Cons of the Mopar 05139084AA Connect Retainer Kit**

1. **Limited Availability and Stock Issues**

Mopar parts, while high-quality, can sometimes be difficult to source, especially for older vehicle models or less common applications. There may be delays in receiving the part, particularly if ordering from a dealership or specialty supplier. This can disrupt repair timelines, especially if the vehicle is inoperable.

2. **Potential for Counterfeit or Low-Quality Alternatives**

While Mopar is a reputable brand, there is a risk of purchasing counterfeit or aftermarket knockoffs that claim to be the genuine part. These fakes may not fit correctly, fail prematurely, or even damage the engine during installation. Always verify the part s authenticity through a trusted dealer or online retailer with a return policy.

3. **Mixed Reviews on Durability**

Some owners report that while the Mopar retainer kit resolves immediate issues, it may not be as durable as the original equipment in high-stress applications (e.g., heavy-duty towing, high-performance modifications, or extreme operating conditions). In such cases, aftermarket high-performance retainers or upgraded materials might be necessary for long-term reliability.

4. **Requires Professional Installation for Complex Cases**

While the kit is designed for ease of installation, some applications particularly those involving timing chains, lifters, or other critical components may require precise alignment or torque specifications. A mechanic with experience in the specific engine family may be needed to ensure the kit is installed correctly, adding to the labor cost.

5. **Not a Permanent Solution for Underlying Issues**

If the retainer failure is symptomatic of a larger problem (e.g., worn lifters, a failing timing chain, or excessive engine wear), replacing just the retainer kit may not address the root cause. Without addressing these underlying issues, the problem could recur, leading to repeated repairs and frustration.

6. **Cost Relative to Other Options**

While the kit is affordable compared to engine repairs, it may still be more expensive than some aftermarket alternatives. For example, third-party retainer kits from brands like Fel-Pro or ATE might offer similar performance at a lower price. However, the trade-off is that these alternatives may not carry the same warranty or fitment guarantees as Mopar.

7. **Potential for Overkill in Some Applications**

If the vehicle is older or has minimal remaining useful life, investing in a retainer kit may not be justified. In such cases, the cost of the kit could be better spent on parts for a more reliable vehicle or a used replacement engine.

### **Conclusion**

The **Mopar 05139084AA Connect Retainer Kit** is a solid choice for addressing retainer-related issues in compatible Chrysler, Dodge, and Jeep engines. Its OEM quality, ease of installation, and cost-effectiveness make it a practical solution for many owners facing retainer failures. The kit is particularly valuable for those who prioritize reliability, warranty coverage, and a direct replacement that aligns with the vehicle s original specifications.

However, the decision to purchase this kit should be weighed against potential drawbacks such as stock availability, the risk of counterfeit parts, and whether the kit alone will resolve underlying engine issues. For high-performance or heavily modified engines, additional considerations such as upgrading to aftermarket retainers may be warranted. Additionally, if the vehicle is nearing the end of its lifespan, the cost-benefit of the kit may not justify the investment.

### **Recommendation**

- You are experiencing retainer-related symptoms (e.g., misfires, excessive oil consumption, or timing issues) in a compatible engine.

- You value OEM quality and warranty coverage.

- The vehicle is otherwise in good condition, and you want to address the issue proactively before it causes further damage.

- You are comfortable with installation or have access to a trusted mechanic for the job.

- The vehicle has extensive engine wear or other known issues that could lead to repeated failures.

- You are on a tight budget and cannot afford the kit or labor costs, and the vehicle s value is low.

- You suspect the retainer failure is part of a larger problem (e.g., worn lifters or timing chain), in which case a more comprehensive repair may be necessary.

- You are modifying the engine for high performance, as aftermarket retainers or upgraded components might offer better longevity.

- Purchase from an authorized Mopar dealer, Chrysler/Dodge/Jeep dealership, or a reputable online retailer with a return policy (e.g., RockAuto, Amazon, or parts specialty stores). Always verify the part s authenticity to avoid counterfeits.

If you are unsure about the root cause of the issue or the compatibility of the kit with your specific engine, consult a mechanic or refer to the vehicle s service manual. This ensures you are addressing the correct problem and selecting the right part for your needs.
