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

Front Upright Knuckle Arms 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 name indicates a metal replacement for standard plastic uprights, intended to provide a stiffer steering pivot and a durable contact point where steering links and wheel hubs attach.

Use these uprights when you want a simple, low-mass chassis upgrade focused on steering precision and repeatable geometry. Swapping to aluminum uprights helps keep toe and camber settings stable during repeated track runs or practice sessions, and can reduce deformation from hard landings compared with stock plastic pieces.

Installation notes: this component is intended for the listed Tamiya models; match existing mounting holes and reuse factory hardware where applicable. Basic disassembly of the front suspension is required to remove the original uprights, and reinstalling the aluminum pieces typically requires 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 mounting point for aftermarket steering components. They are a targeted option for chassis setup work such as adjusting steering ackermann, roll center, and toe characteristics without changing major suspension parts.
