Tamiya 1/14 Truck King Hauler Alloy Radius Arms TRU058 by GPM  [TRU058]

Heavy duty alloy radius arms for 1/14 Tamiya trucks

These alloy radius arms are an aftermarket upgrade for 1/14 scale Tamiya tractor trucks, replacing the original plastic components to give a firmer mounting point for rear suspension links and lower deflection under strain.

The kit is supplied as a 2pcs set and contains collars, lock nuts and mounting screws as indicated in the product title. The parts are intended to use the truck's existing fixing points for a direct swap that emphasises chassis stiffness and repeatable alignment during setup.

Fitting advice: inspect ball bearings and pivot areas for wear, remove the original arms with care, move any required spacers across, fit the alloy arms with the supplied collars and lock nuts, and torque fasteners to a controlled setting to avoid damage. Recheck alignment on the bench and again after a short test run.

For tuning, these arms help keep the rear axle geometry more stable during acceleration and braking, producing a firmer suspension feel and assisting in maintaining consistent gear alignment under load.

Use these alloy radius arms when you want a long-lasting, direct-fit upgrade that reduces rear-end flex and helps preserve setup during track or road use.
