What is a differential cover?
In addition to providing access for changing gear lube, differential covers help dissipate heat that can damage differentials, and they protect gears from contaminants like dirt and water, as well as rocks and other large obstacles encountered when off-roading.
Are aftermarket differential covers worth it?
For most vehicles that are used normally, the factory cover is likely best, but for special applications like hard off-road use, heavy trailer towing or extreme power outputs, the benefits of an aftermarket cover will likely outweigh the negatives.
What does a performance differential cover do?
We highlight performance covers which are stronger, lighter, reduce heat, and add style. Differential covers play an important role in keeping your wheels turning. While allowing easy servicing of your differential fluid, they also create a sealed area that protects gears and gear fluid from dirt and moisture.
Should I upgrade my differential cover?
An upgraded differential cover allows for you to carry more gear fluid oil. This extra fluid equals greater diff cooling. An aftermarket diff cover can also provide heavy, duty protection for your axle parts. This is a common impact point especially for those that like to take their rig off road.
Are aluminum diff covers good?
Cast aluminum covers are lightweight and conduct heat well. Many have fins to aid in cooling the gear oil. Also, many allow for more gear oil to be added to the differential, as compared to stock. With all this cooling, this type of cover can be great for trucks that tow on a regular basis.
Are aluminum diff covers worth it?
An upgraded differential cover helps with cooling in one of three ways. The first being the material itself: aluminum covers will expend heat very well. Aluminum also has a weight advantage. Compared to steel or iron ones, diff covers made of aluminum are also significantly lighter.
Do aluminum differential covers work?
The first being the material itself: aluminum covers will expend heat very well. Aluminum also has a weight advantage. Compared to steel or iron ones, diff covers made of aluminum are also significantly lighter. A second way that a cover can help keep things cool is by design.
Are front and rear diff covers the same?
Registered. The front and rear axle are not the same. The front axle seals are located in the differential housing. The outer axle bearings are sealed units that mount to the knuckle/spindle that’s attached to the axle tube by ball joints.
Are flat back diff covers bad?
“Flat-back diff covers do harm,” says Banks. “They do harm to the lube because they just work the living hell out of it. The fluid dynamics that the OEs have in the stock diff cover shape, you need to pay attention to that; it’s that way for a reason.”
