Genuine Mopar Fluid 4318060AB Limited Slip Additive Review: Is it Worth It?

Proper maintenance of your vehicle's differential is crucial for optimal performance and longevity. One key component of this maintenance is using the correct limited-slip additive. The Genuine Mopar Fluid 4318060AB is designed specifically for Chrysler vehicles (and some others) that require a limited-slip differential additive to reduce friction and chatter within the differential. This 4 oz. bottle aims to provide the right amount of additive to keep your differential operating smoothly and quietly, preventing premature wear and ensuring proper torque distribution. If you've noticed noises or unusual vibrations from your rear axle, this additive might be the solution you've been looking for.

This additive isn't a universal solution for all vehicles. It is specifically formulated for vehicles that use a limited-slip differential, particularly Chrysler, Dodge, Jeep, and Ram models. Using the correct additive is essential because the wrong type can damage the friction plates inside the differential or cause other performance issues. If you're unsure whether your vehicle requires this specific additive, consult your owner's manual or a qualified mechanic. Let's dive into the details and see if this Mopar product lives up to its claims.

Key Features of the Mopar Limited Slip Additive

Here's a breakdown of the key features of the Genuine Mopar Fluid 4318060AB:

  • Specific Formulation: Designed for Chrysler, Dodge, Jeep, and Ram vehicles equipped with limited-slip differentials.
  • Reduces Differential Chatter: Minimizes noise and vibrations caused by friction within the differential.
  • Prevents Premature Wear: Protects the friction plates and internal components of the differential.
  • Ensures Proper Torque Distribution: Maintains the differential's ability to evenly distribute power to the wheels.
  • Convenient 4 oz. Bottle: Pre-measured for easy application and the correct amount for many differential services.

Pros of the Mopar Limited Slip Additive

The Genuine Mopar Fluid 4318060AB offers several advantages for vehicle owners:

  • Guaranteed Compatibility: As a genuine Mopar product, it's specifically formulated for Chrysler, Dodge, Jeep, and Ram limited-slip differentials, ensuring optimal performance and avoiding potential damage from using incompatible fluids.
  • Effective Noise Reduction: Users consistently report a significant reduction in differential chatter and noise after adding this additive. This results in a smoother and quieter driving experience.
  • Prevents Costly Repairs: By reducing friction and wear, this additive helps to extend the lifespan of your differential, preventing the need for expensive repairs or replacements down the road. Think of it as preventative maintenance for your rear axle.

Cons of the Mopar Limited Slip Additive

Despite its benefits, the Mopar Limited Slip Additive has some drawbacks:

  • Limited Applicability: This product is not a universal solution for all vehicles. It is specifically designed for Chrysler, Dodge, Jeep, and Ram vehicles with limited-slip differentials. Using it in a vehicle that doesn't require it could potentially cause harm or performance issues.
  • Price Compared to Alternatives: While the price is relatively reasonable, there are aftermarket limited-slip additives available that may be slightly cheaper. However, using a non-OEM fluid may void your warranty. So, weigh your options carefully.

Who Should Buy the Mopar Limited Slip Additive?

This product is ideally suited for the following users:

  • Owners of Chrysler, Dodge, Jeep, and Ram vehicles with limited-slip differentials: If your vehicle is experiencing differential chatter or noise and your owner's manual recommends this additive, this is a must-buy.
  • DIY mechanics: The 4 oz. bottle is convenient for DIYers who prefer to perform their own differential maintenance. Just be sure you know how to safely access your differential and that you have the right tools to add the additive.
  • Those seeking preventative maintenance: Even if you're not currently experiencing any issues, adding this additive during a differential service can help to extend the life of your differential and prevent future problems. Consult your service manual for recommendations on service intervals.
This additive is NOT for you if you drive a vehicle from a manufacturer other than Chrysler (and its sub-brands) that specifies a different type of limited-slip additive. Always check your owner's manual or consult a trusted mechanic to determine the correct additive for your vehicle. Some Ford vehicles, for example, may require a different formulation altogether.

Conclusion: Is the Mopar Limited Slip Additive Worth It?

The Genuine Mopar Fluid 4318060AB Limited Slip Additive is a worthwhile investment for owners of Chrysler, Dodge, Jeep, and Ram vehicles with limited-slip differentials who are experiencing noise or wish to perform preventative maintenance. While it may be slightly more expensive than some aftermarket alternatives, the guaranteed compatibility and effectiveness make it a reliable choice. Consider using this additive for a smoother, quieter driving experience and to protect your vehicle's differential.

Final Verdict: This additive is highly recommended for compatible vehicles suffering from differential chatter and as a preventative measure. It offers peace of mind knowing you're using the right product for your Mopar vehicle.

Better than the cheap generic pairs you find at the big box stores. The seal around the ears is tight but not "head-crushing" tight, which is a nice change of pace.

Honestly best shaker I've owned. The agitator inside actually works and doesn't make that annoying rattling sound like the wire balls do. It stays cold for hours too which is nice if you're like me and forget your shake in the car lol.
