Top-brand differential covers

The covers at DieselSite.com provide many added benefits. We carry quality Mag-Hytec covers, which meet the manufacturer's rigorous standards. All covers are cast in aluminum with thick walls to reinforce the differential housing. You can be confident the gasket flange will not bend when tightening bolts, and installation is a breeze as the O-rings do not require sealant or gaskets. Stainless steel hardware resists corrosion and a magnetic dipstick doubles as a filter and a means of checking fluid levels. Don't worry about leaking oil, both the drain and dipstick are sealed with O-rings. The cover allows you to conveniently change oil without removing it. High temperatures can eventually destroy fluids and components in your truck. These Mag-Hytec covers allow your truck to hold more oil; and you'll be pleased to find the fluid running about 15 to 20 degrees cooler than before. These name-brand differential covers are texture powder coated in black making them aesthetically distinctive. They come with everything included for installation from start to finish. Their versatility allows them to fit the majority of suspension systems and anti-sway bars. Our diff covers, like everything we carrry is of the highest quality. We always stand behind our diesel parts and their performance.

The company derived their name from the signature magnet suspended in the oil within their differential covers. As axles and transmissions go through their natural wear and tear, they sluff off small metal particles that gradually accumulate in your oil. The magnet passively collects this metal debris from the oil as you drive. This maintains the integrity of the oil and keeps metal particles from interacting with other components in your vehicle. Occasional magnet cleaning keeps the oil pure and your vehicle running at peak performance. Browse our other performance parts and find the right one for your diesel truck.
