LOSI LMT Front/Rear Differential Outdrive 4140 Steel Upgrade - LMT039S by GPM  [LMT039S]

4140 Steel Front and Rear Outdrive for LOSI LMT

This RC-scale replacement outdrive is made specifically for LOSI LMT solid axle monster trucks and is manufactured from 4140 steel to boost wear resistance inside the differential assembly. It serves as the front and rear differential outdrive to restore or extend drivetrain life on 1/8 and 1/10 LMT solid axle models.

The component is intended as a direct swap where compatible with factory part LOS242038. Installation typically involves removing the differential housing, swapping the outdrive, and verifying pin seating and gear mesh alignment before final reassembly. Inspect mating gear faces and pin seating to avoid premature wear.

For tuning and upkeep, upgrading to a hardened 4140 steel outdrive reduces deformation under load and helps keep gear engagement consistent during heavy use, making it a practical upgrade for hobbyists prioritizing drivetrain reliability.
