Upgrade center differential built for LOSI LMT trucks

This aftermarket center complete differential is set up for LOSI LMT 4WD solid axle monster trucks and is constructed from 4140 steel with 7075 alloy machined parts. The unit is supplied fully assembled and includes a 13T pinion and the 13/43T helical gear set at a 1.0 module, intended for drivetrain service, worn part replacement, or performance-focused rebuilds.

The assembly replaces several factory part numbers and fits the LOSI LMT variants listed below. Differential oil is excluded and must be added per LOSI's fill instructions. Small assembly accessories come pre-installed, and applying medium-strength threadlocker to critical fasteners is advised to maintain secure operation under vibration.

Contents: one center complete differential (13/43T) and one 13T pinion gear, both pre-assembled for direct installation. This aftermarket item may need slight fitting during setup; buying two sets is suggested when overhauling both center halves to ensure matched components.

For best results, use the correct differential lubricant and threadlocker during installation to achieve long term reliability in LOSI LMT drivetrains.

How should I approach installing this center differential?

Begin by comparing the unit to your existing center assembly and confirming part numbers. Install with recommended LOSI procedures, use medium-strength threadlocker where indicated, and top up with the appropriate differential oil after seating the gears.

Will gear mesh or shimming be required?

The gears are pre-assembled but slight mesh adjustment or minor fitting can be necessary depending on chassis wear or previous modifications; inspect the mesh and adjust shims if you notice excessive play.

What effect does this unit have on tuning?

Using the 13/43T center with quality lubrication helps provide consistent drivetrain behavior; it does not change the external gear ratio but can smooth power transfer compared with worn factory components.

Is the pinion gear supplied installed or separate?

The 13T pinion and the 13/43T helical gear set are supplied pre-assembled to speed up replacement and reduce assembly time.

Which lubricants are recommended for best performance?

Differential oil is not included. Use the viscosity and type recommended by LOSI for the center differential to avoid premature wear and to maintain predictable handling.

Should I buy two units when servicing the vehicle?

Yes. To ensure matched center halves and reduce the chance of uneven wear, purchasing two sets for a full drivetrain rebuild is recommended by the supplier.
