Center complete differential for LOSI LMT drive systems

This RC-scale center complete differential is assembled for LOSI LMT 4WD solid axle monster trucks and made from 4140 steel and 7075 alloy parts. The unit ships fully assembled and includes a 13T pinion gear plus the 13/43T helical gear set with a 1.0 module. It is intended for chassis drivetrain maintenance, replacement of worn factory components, and as an upgrade option for rebuild projects.

The differential replaces multiple factory part numbers and fits the LOSI LMT model list shown below. Differential oil is not provided and must be added following the LOSI manual instructions. Small assembly items arrive pre-assembled, and applying medium-strength threadlocker to fasteners is advised to reduce the chance of loosening under vibration.

Package contents: one center complete differential (13/43T) and one 13T pinion gear, both pre-assembled for installation. This is supplied as an aftermarket replacement and may need minor fitting during installation; buying two sets is recommended if you are servicing both center halves or completing a full drivetrain rebuild.

Should I purchase extra sets when doing a full rebuild?

The supplier advises buying two sets if you plan to service both center sections or perform a complete drivetrain rebuild, ensuring matched components and less downtime.
