LOSI LMT Solid Axle Differential Outdrive, 4140 Steel - LMT039S by GPM  [LMT039S]

Front and Rear Differential Outdrive Compatible with LOSI LMT

This replacement outdrive is intended for LOSI LMT solid axle monster trucks and is manufactured from 4140 steel to increase wear resistance within the differential. It functions as both the front and rear differential outdrive to restore or extend drivetrain life on 1/8 and 1/10 LMT solid axle vehicles.

When dimensions align, the part can directly replace factory component LOS242038. Installation requires differential housing removal, fitting the new outdrive, and carefully checking pin seating and gear mesh before completing assembly. Inspect mating gear faces and pins to prevent premature wear.

As part of routine maintenance or tuning, upgrading to a hardened 4140 outdrive reduces deformation under load and helps preserve consistent gear engagement during demanding operation, making it a practical option for modelers concerned with drivetrain durability.
