Overview
The Traxxas Stub Axles (Portal Drive) (2) TRX9853 are genuine OEM replacement parts designed for RC models equipped with portal drive systems. These stub axles are essential drivetrain components that connect the portal gearbox assembly to the wheels, ensuring smooth power transmission and reliable handling on any terrain. Whether you're maintaining your RC car UK collection, replacing worn components, or building a custom setup, these Traxxas spare parts offer the quality and precision engineering you'd expect from the world's leading RC manufacturer.
Portal drive systems have become increasingly popular in modern RC vehicles, particularly in crawlers and off-road models, because they provide superior ground clearance and impressive articulation. The stub axles play a critical role in this setup, transferring rotational force from the portal gearbox directly to the wheels whilst maintaining alignment and stability.

This is a two-pack of stub axles, giving you a complete matched pair for perfect symmetry and balanced handling characteristics. Traxxas stub axles are manufactured to exact tolerances and use premium materials to withstand the stresses of competitive racing, weekend bashing, and everything in between.

Technical Performance
Portal drive systems represent an advanced engineering solution in the RC world, and the stub axles are absolutely critical to their function. These components must withstand significant rotational and lateral forces whilst maintaining perfect alignment to the wheel hubs. The Traxxas TRX9853 stub axles are engineered with precision tolerances to ensure smooth operation and minimal runout, which is essential for balanced handling and predictable steering response. The materials and construction method employed by Traxxas ensure that these stub axles deliver years of reliable service even under demanding conditions. Portal drive systems allow for exceptional ground clearance and articulation, and the stub axles enable this performance by providing a robust connection point between the gearbox and wheels. Regular inspection and timely replacement of worn stub axles is one of the most important maintenance tasks you can perform on your RC model, directly impacting handling feel, traction control, and the lifespan of other drivetrain components. When combined with complementary Traxxas drivetrain spares such as the TRX9830 rear axle shafts, these stub axles form the backbone of a healthy, responsive portal drive system.
