LOSI LMT Solid Axle Differential Assembly 13/43T 1.0 Mod LMT1343S by GPM  [LMT1343S]

Direct-fit differential assembly designed for LOSI LMT

The LMT1343S front and rear complete differential is supplied as an aftermarket replacement for LOSI LMT solid axle monster truck kits and RTR vehicles. These units are pre-assembled and use 4140 steel and 7075 alloy components, with the internal helical gear train and an included 13T pinion gear. They are intended for drivetrain repair, scheduled maintenance, and tuning where a straightforward swap of LOSI factory differentials is desired.

Gear and material specifics: the helical internal gearset features a 10T driving gear paired to a 43T driven gear at a 1.0 module to mirror LOSI original geometry. Key structural parts are produced in 4140 steel and 7075 alloy to offer wear resistance while controlling mass. The kit is shipped without differential oil; users should fill the units as part of installation following LOSI instructions or their established practice.

Service guidance: although the assemblies are pre-built, test-fit and verify final torque values on your chassis before returning the vehicle to service. Consider sourcing two sets when replacing both front and rear to ensure matched engagement and consistent wear. Use medium-strength thread locker on external fasteners and adjust gear backlash carefully to avoid accelerated wear.

If you need a reliable aftermarket replacement or stronger assembly for a LOSI LMT, these pre-assembled front and rear differentials use 4140 steel and 7075 alloy; follow LOSI recommendations for oil fill and final torque, and consider replacing both ends to keep the drivetrain balanced.
