Aluminum Front Upper Arms for Hotshot Series

This replacement arm set is designed for Hotshot-platform Tamiya models and is manufactured from anodized aluminium with a black finish to offer a firmer front-end feel compared with stock plastic components.

Mounting matches stock locations and usually accepts original hardware for a straightforward swap on Hotshot, Hotshot II/2, Super Hotshot and Boomerang 4WD. After fitment, check camber and steering geometry to maintain handling balance.

Performance overview: aluminium upper arms reduce compliance at the front axle, tightening turn-in and improving repeatability; pair the arms with tuned shocks and roll-center adjustments for best results.

A reliable aluminium upgrade that improves front-end rigidity and steering precision for Hotshot-series vehicles.

Will these arms bolt on without modifying the chassis?

They are intended to use the stock mounting points on Hotshot variants; a dry-fit is recommended to confirm alignment before final assembly.

Do I need to change any bearings when upgrading?

Most of the time original bearings and screws are reused, but replace any worn or damaged parts you find during installation.

How do these affect front-end tuning?

They stiffen the front axle and can change turn-in characteristics, so adjust shock damping and camber in small steps to dial in the desired behaviour.

What should I inspect after running?

After sessions, clean off grit, inspect for nicks or bends at mounting points, and check that screws remain tight and free of damage.
