This aftermarket differential housing is manufactured to fit ARRMA 1/7 and 1/8 desert truck platforms. The external section is medium carbon steel to improve wear resistance at gear and bearing interfaces, while the centre is machined from 7075 aluminium to reduce rotating mass without losing mounting stability. A rubber sealing ring is included to limit contamination and retain gearbox lubricant.
Intended for drivers who demand durability, the unit helps stabilise gear mesh under heavy loads, reducing premature wear on internal parts. It is a direct-replacement design for compatible ARRMA models; confirm fitment with your chassis and axle layout prior to installation.
Assembly notes: remove the axle or centre gearbox per the vehicle manual, transfer internal differential parts into the new case, install the supplied sealing ring, and torque fasteners to match original hardware recommendations. Check gear backlash and lubrication after assembly and re-inspect after the first run.
