Mag-Hytec's Idea For Cooler Running Drivetrains
Roy Rothlisberger owns a machine shop and is an engineer that is serious about his work. When he came up with the Mag-Hytec cover, it wasn't made to pretty up the axle. With its thick, 1/2-inch lip and O-ring gasket seal, this cover is one of the best we've seen on the market. It also features an oil dipstick with a magnet and a drain plug assembly with a magnet to make changing oil a breeze. The cover is manufactured from 356-T6, high-grade aluminum and has a fitting for a temperature sender. It also features 1/4-inch fins at the rear that actually dissipate heat more efficiently. The cover holds 5 quarts of oil, allowing more of it to get into the axle and properly lubricate the bearings. The kit also comes with stainless steel, hex-head bolts, and installation directions.
Roy also manufactures a transmission pan cover that incorporates the same cooling and maintenance aspects of the differential cover. The cover is obviously much deeper than the factory pan and uses 4 extra quarts of transmission fluid than a stock pan. Furthermore, the Mag-Hytec pan also has a drain plug with a magnet on it as well as the same hex-head stainless bolts that hold it in place. The deeper pan uses a standard transmission oil filter that sits on a baffle, preventing any starvation, yet keeps dirt and grime away from the pickup.
For our installation, we used LE 607 heavy-duty gear oil and LE 7500 transmission fluid.
We took our '95 Suburban to B&F Auto Transmissions where the Mag-Hytec transmission pan and differential cover were installed. The installation was simple, and after driving around with the LE lubricants in the truck, there was a noticeable difference; the shifting improved and was much quieter and firmer than before.
