LOSI LMT 4WD Solid Axle Outdrive Upgrade for Drivetrain Reliability - LMT039S by GPM  [LMT039S]

Replacement Outdrive for LOSI LMT Solid Axles

Specifically produced for LOSI LMT solid axle monster trucks, this replacement outdrive is made from 4140 steel to improve wear resistance in the differential assembly. It serves as the front and rear outdrive to help restore or extend the service life of 1/8 and 1/10 LMT solid axle models.

The design allows it to be used as a direct replacement for factory part LOS242038 where compatible. Installation involves removing the differential housing, swapping the outdrive, and ensuring correct pin placement and gear mesh before completing assembly. Verify mating surfaces and pin seating to avoid early failure.

From a tuning perspective, a hardened 4140 outdrive resists deformation under load and preserves reliable gear engagement during high-stress operation, making it a solid choice for modelers concentrating on drivetrain robustness.
