LOSI LMT Front/Rear Complete Differential 13/43T LMT1343S by GPM  [LMT1343S]

Aftermarket replacement differentials for LOSI LMT

The LMT1343S front and rear complete differential assemblies are designed as aftermarket replacements for LOSI LMT solid axle monster truck kits and RTR models. Components are pre-assembled and combine 4140 steel with 7075 alloy parts, and the package includes the internal helical gears plus a 13T pinion gear. The assemblies are intended for drivetrain maintenance, repairs, or upgrades where direct-fit aftermarket parts are required.

Design notes: the gearset uses a 10T driving gear and a 43T driven gear at a 1.0 module to maintain LOSI gear geometry. Critical load paths use 4140 steel and 7075 alloy to balance durability and weight. Differential oil is not included, so fill the units during installation following LOSI guidance or your preferred setup.

Installation advice: verify final alignment and torque on your chassis despite pre-assembly. Consider replacing both front and rear to preserve matched wear and gear mesh. Use a medium-strength thread locker on external fasteners and set gear lash carefully to avoid premature wear.

For LOSI LMT owners needing a direct-fit aftermarket differential, the LMT1343S assemblies offer pre-assembled front and rear units in 4140 steel and 7075 alloy; follow LOSI recommendations for oil, torque, and matched replacement of both ends when appropriate.
