AXIAL SMT10 Aluminium Heavy Duty Differential Locker by GPM MJ050F/R  [MJ050F/R]

Aluminium differential locker for SMT10

This GPM aftermarket differential locker is an RC-scale aluminium replacement intended for Axial SMT10 platforms and related YETI/Monster Jam models. Designed as a single-piece locker, it replaces a stock differential component to change how power is transferred between wheels under load, offering a predictable locked behaviour useful when tuning traction for rock crawling or monster truck driving.

The part is supplied as a 1pc set and is machined from alloy to resist deformation compared with typical plastic housings. Fitment focuses on chassis compatibility rather than universal fit, so verify alignment with existing axle housings and mounting interfaces before installation. The component acts as a tuning option in the drivetrain, affecting how the vehicle behaves under wheel slip and during tight traction situations.

Use this aluminium locker when you need a durable, RC-scale drivetrain part for SMT10 derivatives and YETI/Monster Jam builds, and plan basic chassis checks before fitting.
