The biggest single beat of the build. We're swapping in a Ford Racing Torsen T2R helical-gear LSD, an MMR rear-diff oil cooler kit and pre-drilled cover, the Circle D Ford 258mm Pro Series 6R80 torque converter, and the Ford Racing oil pan and pump kit. Every one of these parts has a job: keep the rear end planted through MAX 3 sweepers, keep the diff and oil temps under control through long sessions, and tighten up the 6R80 converter for cleaner launches.
