The Importance of a 12 Bolt Differential Cover

As a car enthusiast, I have learned the hard way the importance of having a strong and reliable differential cover. The differential is an essential component of a vehicle’s drivetrain, responsible for transferring power from the engine to the wheels. Without a properly functioning differential, the car would not be able to move.

One of the main reasons why a 12 bolt differential cover is necessary is for its strength and durability. The number of bolts refers to the number of fasteners holding the cover in place. A 12 bolt differential cover is stronger and more secure compared to covers with fewer bolts, making it less likely to break or leak under heavy loads or rough terrain.

Another crucial factor is its ability to dissipate heat. The differential generates a significant amount of heat while in operation, and without proper ventilation, it can cause damage to the gears and bearings. A 12 bolt cover typically has larger cooling fins and more surface area compared to other covers, allowing for better heat dissipation. This prevents overheating and prolongs the life of the differential.

Furthermore, a 12 bolt differential cover provides better protection for the rear axle components. Off-roading or driving on uneven terrain can expose these parts to potential

My Buying Guide on ’12 Bolt Differential Cover’

As a car enthusiast, I have always been particular about the performance and maintenance of my vehicle. One crucial component that I have recently upgraded is the differential cover. After extensive research and personal experience, I have put together this buying guide on ’12 Bolt Differential Cover’ to help fellow car owners make an informed decision.

What is a 12 Bolt Differential Cover?

A 12 bolt differential cover is a protective casing that houses the gears and other internal components of the rear axle in a vehicle. It is named after the number of bolts used to secure it to the axle housing. This type of differential cover is commonly found in vehicles with high-torque engines or heavy-duty towing capabilities.

Why Upgrade to a 12 Bolt Differential Cover?

The stock differential cover that comes with most vehicles is often made of thin metal, which can bend or break under extreme conditions. Upgrading to a 12 bolt differential cover offers better protection and durability, especially for off-roading or towing purposes. The thicker material and additional bolts provide better stability and prevent damage to the internal components.

Factors to Consider Before Buying

  • Material: The material used for the differential cover plays a significant role in its performance. Opt for covers made of heavy-duty materials like cast iron, steel, or aluminum alloy for maximum strength and protection.
  • Bolt Count: As the name suggests, a 12 bolt differential cover has 12 bolts securing it to the axle housing. However, some aftermarket covers may have more or fewer bolts depending on their design. Make sure to check your vehicle’s specifications before purchasing.
  • Gasket: A good quality gasket ensures a tight seal between the differential cover and the axle housing, preventing any leaks or debris from entering. Look for covers that come with high-quality gaskets or purchase one separately if needed.
  • Cover Design: There are different designs available in the market for 12 bolt differential covers, such as flatback, finned, or ribbed. While this does not affect its functionality, you can choose one that complements your vehicle’s aesthetics.
  • Budget: As with any automotive upgrade, set a budget before starting your search for a differential cover. You can find covers ranging from $50 to $300 depending on their material and brand.

Tips for Installation

  • Clean the surface of both the axle housing and differential cover thoroughly before installation.
  • Tighten all bolts evenly using a torque wrench according to manufacturer’s specifications.
  • If you are not familiar with installing automotive parts, seek professional help to ensure proper installation.

Famous Brands in Market

Some popular brands known for their quality 12 bolt differential covers include Yukon Gear & Axle Co., Mag-Hytec, PML Inc., and Dana Spicer Corp. Do your research and read reviews before choosing a brand that suits your needs and budget best.

In Conclusion

An upgraded 12 bolt differential cover not only adds an element of style but also provides better protection for your vehicle’s rear axle components. Consider all factors mentioned above before making your purchase decision. Remember to prioritize quality over price as it will save you from potential damages in the long run.
