GLO Differential Covers

Great Lake Off Road Differential CoverOur cover has always stood out from the competition for several reasons. The first is the fact the design of this cover was my own original intelligent design. With a long fabricating history I knew how to build a better rat trap so to speak. We did not choose to do a cheap imitation of some one else parts. We tested and perfected our covers engineered design to maximize strength. As fellow wheelers / racers the last thing we want to do is leave you stranded on the trail or not able to finish the race.

At GLO we developed the first true two-piece fabricated differential cover on the market. We start by providing a low profile laser cut ½” thick bolt gasket ring as our foundation. The idea was to allow the shaving of many differentials without modifying our cover. Then we add a true one piece ¼” thick laser cut and cnc broke gear cover. To top it off, finally we add a custom machined to our specs fill bung with plug. The plug is an Allen setscrew type plug in a 3/8” national pipe thread which comes in at approx ¾” diameter to fill your fluids. From start to finish we designed this with the best intentions not sacrificing quality in the name of cost and end user satisfaction.

From the start we choose to use a ½” thick bolt ring as our base. My granddad once stated “You don’t put a foundation under an outhouse” and the same theory applies here as well. Once this is fixture welded there is no room for any deflection. The single piece ¼” gear cover just made sense, why weld it from several pieces when one from the start is stronger? Overall uniform strength with less weld areas to create an opportunity to break and tear upon impact. Face it guys, gals these covers are right out in front and need to be able to withstand a hard blunt force trauma. Our two welders have over forty years combined experience to create some of the best looking welds on the planet. The quality in the welds is top notch and you will not be disappointed upon opening your box when it arrives. This cover upon purchase is complete and ready to go to work for you. It does not need to be assembled nor do you need to grind out the welds because they are not up to your standard or what you would expect from a quality fabricated piece. The only option this cover does not have before leaving our shop is to weld this unit up your self. The reason for this is in our warranty. We stand behind every cover we build with our lifetime stamp of approval. You break it we replace it no BS included.
