Kit overview and fit

This aluminium front upper arm kit is intended for TAMIYA Hotshot family chassis and Boomerang 4WD, offered as model JR-THS04-GU. The parts feature a gun metal finish and are supplied as a replacement option for the listed models.

These arms are aimed at enthusiasts who want firmer steering geometry and a reliable mounting interface versus stock plastic arms. They help maintain consistent link positions when adjusting camber or caster during setup changes on the track or during club runs.

Fitting advice: check all fasteners and pivot items before final assembly, verify the steering throw and suspension travel after installation, and make incremental changes to shock preload or ride height to tune handling after the swap.

If you want a metal upgrade for the front upper arms on the listed TAMIYA platforms, these components provide consistent fitment and improved durability while keeping standard mounting points.

How should I check fitment before tightening?

Perform a dry assembly to ensure holes line up and the steering arms clear other components. Rotate the steering and compress the suspension to confirm full travel without interference.

Are any washers or spacers needed when fitting these arms?

Most installations reuse the stock hardware. Keep original washers or spacers and fit them as before; only change if the dry fit shows binding or excess clearance.

Do these arms change recommended camber settings?

Because aluminum is stiffer, you may see different camber behavior under load. Re-check static camber and perform a quick on-track test to fine tune settings after installation.

Will the finish chip or corrode?

The gun metal finish resists wear under normal use, but inspect for nicks after impacts and touch up or replace if damage compromises function.

Can I use these arms for competition tuning?

Yes. They are suitable as part of a staged tuning strategy to stiffen the front end and deliver more predictable steering inputs for competitive setups.
