JAZRIDER aluminium rear knuckle arm technical overview

The JAZRIDER JR-TA109-GU rear knuckle arm in gun metal is a practical aluminium upgrade for Tamiya TA01, TA02, DF01 and FF01 chassis. It replaces the original plastic component with a machined aluminium unit to reduce flex and improve part longevity under regular use.

Fitment and expected behaviour

Intended for direct fitment to the listed Tamiya platforms, this aluminium arm maintains OEM geometry while increasing torsional stiffness at the rear hub. The result is reduced deflection during hard cornering and more consistent tyre contact for predictable handling.

Installation guidance and maintenance

Install with standard RC tools, using the stock fasteners where applicable. Periodically check fastener torque and inspect bearing seats for wear. The aluminium construction resists cracking common to plastic parts, making it a reliable long term upgrade for everyday hobby use.

Does the aluminium arm require modified hardware?

No. The JAZRIDER JR-TA109-GU is designed to use the stock mounting points and common fasteners for the compatible Tamiya models.

How does aluminium affect suspension tuning?

The stiffer knuckle reduces unwanted compliance at the hub, which can make damping and anti-roll balance feel more direct. Minor setup adjustments to damping or toe may be used to optimise handling.

Recommended inspection routine?

After heavy sessions, verify fastener torque and check for hairline damage. Clean mounting faces and bearings to ensure consistent fit and performance.
