This aluminium rear knuckle arm is provided as an aftermarket replacement for the Tamiya TT02B RC chassis. The part swaps the factory plastic component for a stiffer alloy unit while maintaining the chassis suspension layout.
It is intended for the TT02B rear suspension and steering link mounting points and is commonly fitted when drivers want metal longevity and a consistent pivot for fine tuning rear traction. The arm uses the stock mounting positions on the chassis and hub carrier so original TT02B hardware and fitting steps apply.
Install this alloy knuckle for scheduled maintenance or when experimenting with rear tuning on a TT02B; confirm clearances and correct fastener lengths during fitment.
