Q: Will this locker work with my 1987 chevy k10 with a 12 bolt rear end Answer this question

A: Hi Terry Te 1987 GM Trucks should have a 8.5" 10 bolt unless somebody has changed it. The aub5420104 is for the GM 12 Bolt Passenger Car rear axle and not the 12 Bolt Truck rear axle. I f somebody swapped a 12 bolt we will need to know the gear ratio you have in it as there are three different carriers to fit the different ratios. if your truck still has the original 8.5" 10 Bolt the proper carrier will be the AUB542018 with 28 spline axles. Thank You

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
