Tamiya 1/14 King Hauler Radius Arm Set TRU058 by GPM  [TRU058]

Alloy radius arm set for Tamiya 1/14 tractors

This aftermarket alloy radius arm assembly is made for 1/14 scale Tamiya tractor trucks and replaces the stock plastic arms for a more secure rear linkage mount. The alloy construction helps limit flex when running or tuning the truck.

Sold as a 2pcs set, the package contains collars, lock nuts and mounting screws as referenced in the product name. These components are intended to mate with the truck's original mounting points for an easy swap that focuses on chassis rigidity and repeatable setup.

Fitment tips: check the condition of bearings and pivot sleeves before beginning, carefully remove the original plastic arms, transfer any required spacers, install the alloy arms with the supplied collars and lock nuts, and apply medium torque to avoid stripping threads. Verify alignment on the bench and after a brief shakedown run.

In practice, the arms stabilise the rear axle geometry under acceleration and braking forces, delivering a firmer suspension response and helping to keep gear mesh consistent under load.

Ideal for modelers wanting a robust, direct-fit upgrade to reduce rear suspension movement and preserve setup during tuning and use.
