GPM Racing 7075 Alloy Rear Knuckle Arm (Larger Inner Bearings) for Tamiya 1/10 Hotshot II 2024-58737-a (HS2022)

Technical rear knuckle for HOTSHOT II

The HS2022 rear knuckle arm is an aftermarket replacement designed specifically for the TAMIYA 1/10 HOTSHOT II platform. Machined from 7075 alloy, the component is engineered to combine low mass with increased tensile strength for hobby applications. The revised bearing seat layout relocates and enlarges the inner seats to enhance bearing positional accuracy and deliver smoother CVD rotation, helping to stabilise rear drive inputs and refine steering response while maintaining original chassis geometry.

This component replaces the factory rear knuckle arms to provide improved bearing fit and reduced CVD play. The result is a firmer bearing location that reduces lateral movement under load, making rear behaviour more predictable during directional and throttle transitions. Intended for hobby RC use only, the HS2022 is specified for the listed HOTSHOT II chassis.

Packing includes

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

Compatible Models

• TAMIYA 1/10 HOTSHOT II 2024-58737-A

Use the HS2022 where precision bearing support and smoother CVD rotation are required on a TAMIYA HOTSHOT II chassis; it is a direct aftermarket upgrade to improve rear stability and steering feedback.

What are the exact benefits of the enlarged inner bearing seats?

Enlarged inner seats allow a more secure bearing fit and improve axial positioning, which lowers lateral play and produces smoother CVD rotation under torque.

Does the HS2022 require special bearings?

The packing includes four 5x13x4 bearings which are compatible with the enlarged seats. Verify bearing runout and replace if necessary for precision setups.

Are any chassis modifications needed?

No chassis modifications are required. The HS2022 is designed as a direct replacement using existing mounts and hardware for the specified HOTSHOT II model. Write Product Review Please sign in your account before you can write any review. Sign In Close
