Ford 9in Alm Diff. Case 3.812

Moser Aluminum Cases are made of 206-T4 aluminum with 7075-T6 aluminum caps and billet steel adjusters. They feature a super strong through-bolt design to give the case increased strength and decreased ring gear deflection common in most aluminum case designs. Available in 3.062, 3.250, and 3.812 bore sizes; all Moser Aluminum cases are drilled for the 3/8 stock pinion studs and 7/16 heavy-duty studs. The 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. Moser Performance Cases weigh only 16 lbs., 15 lbs. lighter than our Nodular Iron Cases, are CMM checked for machining accuracy, and are supplied with all Grade 8 hardware.
