As an avid off-roader and mechanic, I have had my fair share of experiences with different types of differentials. And let me tell you, investing in a high-quality differential cover is crucial for any serious off-roading enthusiast. In my opinion, the GM 12 bolt differential cover is one of the best options out there and here’s why.

First and foremost, the GM 12 bolt differential cover provides superior strength and durability compared to other stock covers. The stock covers are typically made of thin stamped steel which can easily bend or crack under extreme conditions. This can result in costly repairs or even worse, a breakdown in the middle of nowhere. The GM 12 bolt differential cover, on the other hand, is made of thick cast iron or aluminum which can withstand heavy impacts and intense off-road conditions.

Moreover, the GM 12 bolt differential cover also offers better heat dissipation. Off-roading can put a lot of strain on your vehicle’s components, including the differential. With a stock cover, there is limited ventilation which can lead to overheating and eventual failure of the differential. The GM 12 bolt differential cover has built-in cooling fins that help dissipate heat more efficiently, ensuring that your differential stays cool even during intense off-road sessions.

My Buying Guide on ‘Gm 12 Bolt Differential Cover’

As a car enthusiast and someone who loves to work on my own vehicles, I have come across many different types of differential covers. However, for my GM vehicle, I have found that the Gm 12 Bolt Differential Cover is the best option. In this buying guide, I will share my personal experience and provide all the necessary information you need to know before purchasing a Gm 12 Bolt Differential Cover.

What is a Gm 12 Bolt Differential Cover?

A Gm 12 Bolt Differential Cover is an aftermarket replacement for the stock differential cover that comes with most GM vehicles. It is designed to fit specifically on GM’s 12 bolt rear end differential, which is commonly found in GM muscle cars and trucks.

Why should you consider upgrading to a Gm 12 Bolt Differential Cover?

The stock differential cover on most GM vehicles is made of thin cast aluminum and can be easily damaged from rocks or other debris on the road. This can lead to leaks and eventually cause damage to your differential. The Gm 12 Bolt Differential Cover is made of heavy-duty cast aluminum or steel, making it more durable and able to withstand rough terrain.

In addition, the Gm 12 Bolt Differential Cover also has extra cooling fins which help dissipate heat from the differential fluid, keeping it at a safe operating temperature. This can help prolong the life of your differential and improve overall performance.

Things to Consider when purchasing a Gm 12 Bolt Differential Cover

  • Material: As mentioned earlier, the Gm 12 Bolt Differential Cover comes in either heavy-duty cast aluminum or steel. Both materials are strong and durable, but steel covers offer better protection against impacts.
  • Cover Style: The Gm 12 Bolt Differential Cover comes in different styles such as finned, smooth or ribbed. Each style has its own benefits – finned covers offer better heat dissipation while ribbed covers provide extra strength.
  • Bolt Pattern: It is important to ensure that the bolt pattern of your new differential cover matches that of your vehicle’s rear end. The Gm 12 Bolt Differential Cover comes with either a standard four-bolt or six-bolt pattern.
  • Gasket Type: Most aftermarket differential covers do not come with gaskets included. Make sure to check if your chosen cover requires a silicone gasket or rubber O-ring for installation.

Tips for Installation

If you have some mechanical knowledge and tools, installing a new Gm 12 Bolt Differential Cover should not be too difficult. However, here are some tips to keep in mind:

  • Cleanliness: Make sure to clean both surfaces where the new cover will be installed thoroughly before applying any sealant or gasket.
  • Tightening Sequence: When tightening the bolts on your new cover, it is important to follow a specific sequence rather than just randomly tightening them down.
  • Torque Specs: Always refer to your vehicle’s manual for recommended torque specs when installing any new parts.

In Conclusion

The Gm 12 Bolt Differential Cover is an excellent upgrade for any GM vehicle with a 12 bolt rear end differential. Its durability and improved cooling capabilities make it worth considering for anyone looking to improve their vehicle’s performance and protect their differential from potential damage. Just make sure to consider all factors mentioned above before making your purchase and follow proper installation procedures for optimal results.
