LOSI LMT Front & Rear Complete Differential 13/43T 1.0 Module LMT1343S by GPM  [LMT1343S]

Drop-in differential assemblies for LOSI LMT

The LMT1343S front and rear complete differential is an aftermarket option manufactured for LOSI LMT solid axle monster truck kits and RTR models. Each assembly is delivered pre-assembled and combines 4140 steel and 7075 alloy components, including the helical gear set and the included 13T pinion gear. It serves as a direct-fit replacement for drivetrain maintenance, repair, or setup experimentation.

Mechanical details: the internal helical gearing uses a 10T driving gear matched to a 43T driven gear at a 1.0 module, which aligns with LOSI original gear geometry. Load-bearing components use 4140 steel and 7075 alloy to balance longevity with manageable mass. The item ships without differential oil; add your chosen lubricant during installation following LOSI guidance or your tuning plan.

Practical advice for installation: while supplied pre-assembled, verify final alignment and torque on your chassis. Consider replacing both front and rear assemblies together to maintain consistent mesh and wear. Apply medium-strength thread locker to exposed fasteners and adhere to LOSI torque figures. If you adjust gear lash, do so incrementally to prevent premature failure.

For LOSI LMT users wanting a reliable aftermarket replacement or a stronger alternative to factory diffs, these pre-assembled units in 4140 steel and 7075 alloy simplify installation; remember to fill with oil and set final torque per LOSI instructions.
