Tamiya TT-02B and DF-02 Aluminum Rear Knuckles for Tuning - JR-TT2B03-GU by Jazrider  [JR-TT2B03-GU]

Alloy rear knuckles optimised for handling

These gun metal aluminium rear knuckle arms are made as performance replacements for the plastic knuckles on Tamiya TT-02B and DF-02 models. They maintain the original suspension geometry while offering a firmer interface at the rear hub.

Installation uses the stock mounting pattern; remove the original plastic parts and fit the aluminium arms with the existing hinge pins and hardware. Standard builds normally need no trimming, though confirm clearances if you run wide tyres or different wheel offsets.

From a setup perspective, alloy knuckles lower compliance around the hub pivot which helps keep rear toe more consistent during cornering. That steadiness can make fine tuning toe and rear roll behaviour easier for experienced drivers.
