Outdrive Replacement Designed for LOSI LMT

This replacement outdrive is built for LOSI LMT solid axle monster trucks and is produced in 4140 steel to improve contact durability within the differential. It is intended to act as the unit for both front and rear differentials on 1/8 and 1/10 LMT solid axle vehicles.

Where dimensions align, the part installs as a direct swap for factory item LOS242038. Typical installation steps include removing the differential housing, exchanging the outdrive, and confirming pin fit and gear mesh alignment prior to final assembly. Check gear faces and pin seating to prevent accelerated wear.

Upgrading to a hardened 4140 outdrive reduces bending and wear under heavy loads, helping maintain consistent gear engagement during demanding runs and making it suitable for hobbyists focused on drivetrain longevity.

How do I confirm fit before tightening?

After placing the outdrive, check axial and radial clearance and hand-rotate the differential to detect binding. Only tighten once gears mesh smoothly and pins are fully seated.

Does material change affect gear wear?

Yes. The 4140 steel construction increases hardness at contact surfaces, which helps resist wear and retain gear geometry under continuous stress.

Should I inspect other drivetrain parts when replacing?

Inspect mating gears, pins, and bearings for wear or damage and replace worn items to prevent accelerated wear on the new outdrive.
