Package Includes:

(1) Mini Spool (Choose Axle Spline Count Above)

- Our GM 8.5" 10 Bolt Mini Spool fits early model GM 8.5" 10 Bolt front and rear ends. You can choose between 28 or 30 spline applications above. This mini spool replaces the spider gears inside your stock open style carrier. After assembly, power will be distributed to both tires 100% of the time, giving you a true locking/locked differential. This mini spool only fits open style carriers, not positraction carriers, and does not fit 1999-Up GM 8.6" applications. Check out our GM 8.6" conversion kit which includes a new carrier, mini spool, cross shaft, and cross pin!

- Rigid Axle is proud to offer our customers a full line of differential, transfer case, and transmission parts. We specialize in complete rebuild kits for domestic cars and trucks. Give us a call with your year, make, and model and we'll build you a custom kit for your build!
