Upgraded rear knuckle arm for HOTSHOT II

Made for the TAMIYA 1/10 HOTSHOT II chassis, the HS2022 rear knuckle arm is an aftermarket 7075 alloy component designed to replace the standard knuckles. The 7075 alloy construction keeps the weight competitive while offering strong tensile properties suited to hobby off-road and on-road use. The inner bearing seats are repositioned and enlarged to improve bearing alignment and CVD rotational smoothness, which helps steady rear drive inputs and sharpen steering reaction without changing chassis geometry.

Installation is direct: the HS2022 swaps in for the stock rear knuckle arms and gives more accurate bearing placement and a firmer bearing fit. Reduced CVD play under load contributes to more consistent rear behaviour during cornering and throttle shifts. This item is intended for hobby RC application and matches the listed HOTSHOT II chassis spec.

Packing includes

  • Rear Knuckle Arm - 2pcs
  • Bearing 5x13x4 - 4pcs

  • TAMIYA 1/10 HOTSHOT II 2024-58737-A

Install HS2022 to tighten bearing support and smooth CVD rotation on a TAMIYA HOTSHOT II chassis; it serves as a direct aftermarket hop-up to enhance rear stability and steering consistency.

Does this require changes to suspension settings?

No suspension geometry changes are needed. The part improves bearing support and CVD rotation which can subtly affect handling, but spring and damping settings can remain as before.

Are the supplied bearings compatible out of the box?

Yes. The kit includes four 5x13x4 bearings which fit the enlarged seats. Verify smooth rotation after installation and replace any bearing that feels gritty.

What benefits will I notice on track or trail?

Expect firmer rear response and reduced play under acceleration, which helps with predictability during corner exits and mid-corner throttle inputs.
