Team Associated RC10B74.1/RC10B74.1D Factory Team LTC Plastic Differential Rebuild Set. This is an optional differential rebuild set intended for the RC10B74.1 and RC10B74.1D. This differential rebuild uses the updated LTC (Low Torque Capacity) gearset allowing for improved driveability and traction. The high tooth count on the gears makes for smoother differential action that won't lock on power.
