GPM Racing 4140 Steel + 7075 Alloy Front&center&rear Complete Differential 13/43T/1.0 Mod for Losi Team Losi 1/8 LMT 4WD Solid Axle Monster Truck (LMT1343S/3)

Complete differential set overview

This LMT1343S/3 complete differential set is an aftermarket replacement designed for LOSI LMT solid axle platforms. The kit supplies fully assembled front, center and rear differentials built with 4140 steel and 7075-T6 aluminium components and helical gearing to match the original 13/43T gear pairing with a 1.0 module pitch.

Purpose-built for RC monster trucks that use LOSI LMT architecture, the set restores front, center and rear drivetrain function without requiring internal assembly. The package does not include differential oil so fluid choice and fill procedures should follow the LOSI manual or your established tuning preferences.

For stability after fitting, it is recommended to use medium-strength screw glue on critical fasteners to reduce the risk of loosening under heavy duty use. All fitment and service steps should be carried out with standard RC tools and reference to the vehicle service manual.
