TAMIYA Hotshot/Hotshot II/2/Super Hotshot/Boomerang 4WD Aluminum Front Upper Suspension Arms by JAZRIDER JR-THS04-GU  [JR-THS04-GU]

Front upper suspension arm overview

This is an RC-scale front upper suspension arm set offered for Tamiya Hotshot family chassis and Boomerang 4WD, supplied by JAZRIDER under model JR-THS04-GU. The parts are aluminum with a gun metal finish and intended as a direct replacement option where listed compatibility is specified.

The arms serve a tuning role in the suspension system, increasing rigidity compared with typical plastic components and providing a consistent mounting interface for steering and suspension linkages. Use them as part of a measured upgrade path when adjusting camber, caster, or overall front-end response on track or recreational runs.

Installation notes: verify fitment against your chassis before final assembly, retain or inspect existing hardware and ball joints for wear, and test steering travel and suspension articulation after installation. Small adjustments to ride height or shock preload may be necessary to rebalance handling after switching to aluminum components.

For hobbyists seeking a metal alternative for the front upper arms on the listed Tamiya chassis, these units offer a stable upgrade for tuning and durability while maintaining standard mounting points.
