Tamiya TA01/TA02W/DF01/Hotshot Front Upright Knuckle Arms, Aluminum - JR-TA101-BK by Jazrider  [JR-TA101-BK]

Aluminum Front Upright Knuckles for Tamiya Chassis

This uprights set is an aluminum front upright knuckle arm designed for Tamiya TA01, TA02W, DF01 and Hotshot chassis configurations. The part replaces standard plastic uprights to give a stiffer steering pivot and a more durable mounting point where steering links and wheel hubs connect.

Use these uprights when you want a low-mass chassis upgrade focused on steering precision and stable geometry. Swapping to aluminum uprights helps keep toe and camber settings consistent during repeated track sessions and reduces deformation from hard landings compared with stock plastic parts.

Installation notes: this component is intended for the listed Tamiya models; align the existing mounting holes and reuse factory hardware where applicable. Basic front suspension disassembly is required to remove the original uprights, and reinstalling the aluminum pieces typically needs a hex driver and the same screws or ball studs used on the original arms.

Tuning role: fit these uprights when refining steering response or when you need a more rigid anchor for aftermarket steering components. They are suitable for setup work such as adjusting ackermann, roll center, and toe without changing major suspension pieces.
