Revolution Design Racing Products have introduced a new aluminium front/rear differential case for the Team Associated B74 buggy. The case is machined from aircraft-grade 7075-T6 aluminium and it sports a heatsink design to further help with heat dissipation. Using the part over the standard composite cage not only improves the precision of the drivetrain, the greatly improved heat transfer also keeps the diff oil much cooler – compared to using the standard plastic case – which results in a much more consistent drivetrain behaviour over the full run; even in high ambient temperatures. The diff case comes hard anodised for wear and looks and it includes a set of suitable inner cross pins for the internal gears. The part fits the B74 buggy equipped with the standard gear differentials.
