Q: Looking to improve traction on my 2012 JK (2door) Sport. I wanted to use a True Trac with my stock 4:10 gears. However!, it has to have it's holes drilled lager to fit stock/factory gear sets. Or would have to have after market gears. Does this product have the same issue? Or will it bolt right in? Answer this question

A: Hello This unit needs to be drilled also but is a cast case so it drills easy compared to the TrueTrac. The TrueTrac is a billet steel case which is much harder than the Auburn. The reason most companies don't drill their units all of the old 44 had 3/8th inch bolts. The Auburn can be drilled with a normal hand drill or in a drill press. Thanks

Q: What type of anti-slip differential does the new Ram 1500 trucks use for the option? At my wits end trying to find out. Are they any good? Can they be changed to an electric locker?

Q: will this fit my 2000 chevy silverado 2wd? Do I need any other parts besides this one? Answer this question

A: Hello Your Silverado should have the GM 10 bolt 8.6 30 spline. The Auburn for that axle is the AUB542097. The only thing you would need besides the limited slip is the carrier/differential bearings. The part number for the bearing kit is D/S 706988x. This kit has both bearings and races.

Q: Need help figuring out what limited slip diff lock and what 373 ring and pinion gear will work in my 86 c10 glove box code says its a gu2 just dropped a 383 stroker with th350 trans I was told the limited slip and 373 gears will make it run like I want it to Answer this question

A: Hello EZ You are correct the 373's will get your truck off the line pretty quick. The GU2 is the 273 gears and you also have 28 spline axles. If it was mine I would do 30 spline axles with a Eaton True Trac with 373's Gears G/2 2-2021-373 install kit G/2 35-2021L TrueTrac EAT 913a481 2) axles G/2 95-2021-005 to upgrade the axles it is just the cost of two axles. So for 200.00 bucks you get the HD axles all the other parts run the same price. Thanks

Auburn Gear's differentials are produced from design to production in their 250,000 sq. ft. plant in Auburn, Indiana. Auburn Gear has been in the manufacturing business in the United States for 60 years. Before making differentials for Jeeps, Auburn Gear manufactured for the busing, aerial lift, agricultural, mining, forest, marine and heavy construction industries. In addition to the plant itself, Auburn Gear's property includes 44 acres. So when they design differentials, they actually install them in Jeeps and then drive them around the trails on their own property to see how they perform. This is how Auburn Gear brings customers excellent quality and we proudly carry many of their products. Shop Auburn Gear Now
