LOSI LMT 4WD Solid Axle Differential Upgrade 13/43T 1.0 Mod - LMT1343S by GPM  [LMT1343S]

Heavy-duty front and rear differential for LOSI LMT

The LMT1343S front and rear complete differential is an aftermarket replacement tailored for LOSI LMT solid axle monster truck kits and ready-to-run variants. Each assembly arrives pre-assembled and uses a combination of 4140 steel and 7075 alloy parts, including the internal helical gear set and the supplied 13T pinion gear. This unit is intended for drivetrain repair, routine maintenance, and track or bash tuning where a direct-fit aftermarket replacement is required.

Technical summary: the internal helical gears comprise a 10T driving gear and a 43T driven gear at a 1.0 module, preserving the original LOSI gear geometry. Critical load components are manufactured in 4140 steel and 7075 alloy to improve wear resistance without excessive weight. Differential oil is not included; fill the units during installation following LOSI guidance or your established lubricant setup.

Fitment and servicing tips: although supplied pre-assembled, confirm alignment and mesh with your chassis before final torque. To keep gear wear consistent across the driveline, consider replacing both ends at once. Apply a medium-strength threadlocker to exposed fasteners to limit loosening from vibration, and observe LOSI torque recommendations. Adjust gear mesh carefully to avoid accelerated wear.

Owners of LOSI LMT wanting rugged, ready-to-fit front and rear differentials will find these pre-assembled units offer a mix of 4140 steel and 7075 alloy for improved service life; remember to add oil and set final torque per LOSI instructions.
