*All orders require your core to be sent in, and must include the cast front cover. We do NOT have any spare T-cases at this time. Sick of breaking your T-case? Need a reasonably priced upgrade? The Boostin Performance 300M upgraded T-case is your answer!! This upgrade starts with rebuilding your core. Seals are replaced, everything is re-shimmed for high horsepower applications, and the bearings are replaced, if needed. The foundation of the upgrade is a 300M output shaft and bored out tail shaft housing. This will mate up with your 25-spline Drive Shaft Shop driveshaft. This T-case upgrade is proven to hold 1.2 60 ft times and is built to withstand the abuse!!
