Aluminum Cases are made of 206-T4 aluminum with 7075-T6
aluminum caps and billet steel adjusters. Features a super strong
through-bolt design to give the case increased strength and
decreased ring gear deflection common in most aluminum case
designs. All bolt-through aluminum cases are drilled for the 3/8
stock pinion studs and 7/16 heavy-duty studs. Our aluminum
cases are also designed to be used with either a standard pilot
bearing with snap ring retention, or a heavy duty, wider pinion
bearing utilizing button head bolts for retention is available. Bolt-
through aluminum performance cases weigh only 16lbs, 15lbs
lighter than our Nodular Iron Cases. All cases are CMM checked for
machining accuracy, and are supplied with all Grade 8 hardware.
