1:14 Rear Axle, axle assembly, diff lock

A driven rear axle is one of the defining mechanical elements in a scale truck build, and this 1:14 assembly brings that focus straight to the chassis with a differential lock and fixed drive. The compact axle layout adds a technical, workshop-style presence to model truck projects while supporting a more purposeful drivetrain setup. The axle is designed for TAMIYA trucks or vehicles with 62 mm frame width, giving the build a clearly defined compatibility point. Inside the housing, the assembly uses gears, bearings and shims, with instruction steps showing bearing sizes such as 9 x 5 x 3 mm and 11 x 5 x 4 mm as part of the internal layout. Separate shaft and cover options are provided for axle setups with or without through-drive, so the drivetrain configuration can follow the chosen chassis concept. Set screws, spacers and the enclosed gear housing all contribute to a model component that rewards careful mechanical assembly rather than hiding the engineering. In a scale truck project, the axle suits fresh builds, drivetrain conversions or the replacement of an existing rear unit. Combined with a matching frame layout, it supports a detailed underbody look and a more technical build process that will appeal to hobbyists working on 1:14 commercial vehicle models.
