Product overview and fitment

This aluminium front upper arm set fits TAMIYA Hotshot models and Boomerang 4WD and is sold as model JR-THS04-GU. The parts are machined from aluminum with a gun metal finish and offered as a direct replacement option for the listed chassis.

Designed to add stiffness compared with stock plastic arms, these components provide a stable mounting point for steering and suspension linkages and support predictable handling when you adjust camber or caster. Use them as part of a stepwise tuning strategy on track or in recreation.

Installation tips: verify alignment with your chassis during a trial assembly, inspect existing fasteners and ball joints for wear, and test steering sweep and suspension articulation after final installation. Minor ride height or shock-preload changes may be needed to rebalance handling following the upgrade.

How do I confirm compatibility before purchase?

Compare the listed compatibility against your chassis model and revision. If unsure, perform a dry fit on the vehicle to confirm hole alignment and clearance.

What should I inspect during installation?

Check screw threads, ball joints and pivots for wear, ensure parts seat flush, and confirm there is no binding through full steering and suspension travel.

Are there any setup tips after fitting aluminium arms?

Re-evaluate camber and toe under static and dynamic conditions; small shock-preload tweaks often help restore the handling balance after switching to metal arms.

How durable are these compared with plastic arms?

The aluminium construction increases resistance to wear and flex, though severe impacts can still bend or damage metal parts; inspect after heavy use.

Maintenance recommendations?

Keep pivot areas free of debris, monitor mounting holes for elongation, and re-torque fixings after initial runs to maintain secure fitment.
