JR-THS02-GU rear knuckle arms for Hotshot

This aluminum rear knuckle arm kit is made for Tamiya Hotshot and Super Hotshot chassis as a metal swap for stock plastic knuckles. Finished in gun metal, the alloy parts reduce flex around the hub and suspension pivot while offering a cohesive look.

They are intended to be fitted with the vehicle's existing rear hub hardware and mounting points, enabling a direct replacement without chassis modification. The upgrade increases mounting rigidity and helps protect against breakage in demanding conditions.

Used alongside suspension or drivetrain changes, the stiffer knuckles can influence rear-end behaviour under acceleration and cornering. These arms suit hobbyists seeking a reliable metal alternative that preserves original geometry for competitive or heavy-use applications.

Are these a direct swap for the standard knuckles?

Yes. The parts are made to use the OEM mounting points and hardware so they replace the factory knuckles without altering the chassis.

What benefits do aluminum knuckles provide?

Aluminum improves resistance to breakage and reduces flex at load points, giving a firmer hub attachment and typically longer service life compared with plastic components.

Should I adjust my setup after fitting these?

It can be beneficial to review spring and damper settings after fitting, since the increased stiffness at the rear hub may change handling characteristics, especially under power.
