COMPLETE ALUMINUM CENTER SECTION
Save up to 14 lbs with a Moser Aluminum case. Our thru-bolted center is one of the strongest units on the market. Moser aluminum cases are made of 356-T6 aluminum with 7075-T6 aluminum caps and billet steel adjusters. They feature a super strong thru-bolt design to give the case increased strength and decreased ring gear deflection common in most aluminum case designs. All Moser Aluminum cases are drilled for the 3/8” stock pinion studs and 7/16” heavy-duty studs. Moser aluminum cases are 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. Step up to the best thru-bolted aluminum center section on the market!
