The GPM LMT011 differential case for LOSI LMT 4WD Solid Axle Monster Trucks combines medium carbon steel with 7075 aluminium components to deliver improved structural strength and reduced inertial mass. This balance helps protect internal gears under heavy loads while limiting added weight on the axle assembly. The supplied rubber sealing ring improves the sealing interface to help keep lubricant in and contaminants out during demanding running conditions.
