Spider 9 Axle Housing Buildup - Building A Spider 9

Posted in How To on July 1, 2010

Last month we provided an overview of the parts we'd use to build a Spidertrax Spider 9 rear axle assembly for our Jeep Cherokee prerunner/rock-crawler. With parts in hand we traveled to Tri County Gear in Pomona, California, to carry out the build.

Tri County Gear in Pomona, California, completed the build of our Spider 9 axle housing using components from JT’s Parts & Accessories, Nitro Gear & Axle, Moser Engineering, and Teraflex. The performance 9-inch rear axle assembly will be installed under a prerunner/rock-crawler Jeep Cherokee.

The Spidertrax Spider 9 axle housing assembly is a purpose-built unit designed for extreme applications. It uses a standard Ford 9-inch drop out and accepts all Ford 9-inch parts and accessories. Since we'd use the Spider 9 assembly under a prerunner/rock-crawler-type rig we opted to go big with the internal components. Internals included a set of Moser 35-spline custom length axle shafts and Nitro Gear & Axle 5.13 ring and pinion gears and 35-spline steel spool, both from JT's Parts & Accessories. The gears and spool are installed in a Nitro nodular-iron race housing, which also features a heavy-duty 1350 pinion yoke and an aluminum Daytona pinion support, both by Nitro Gear & Axle.

Check out the following series of photos as we walk our way through the Tri County Gear assembly process to create a heavy-duty rear axle for our Cherokee prerunner/rock-crawler.
