This case has been redesigned inside to allow the case to hold over 2 times as much diff fluid. This will give you more consistent diff action thru the entire run in a long main. M2C also added spider gear (small inner gears) shims to cut down on friction. These are custom hardened shims that will not rotate in the case so there will no wear on the diff case.
Note: this diff case only fits the nitro models; for the electric model center diff see part: M2C6900
