The JR-DT307-RD aluminum rear hub carrier is a precision replacement for the Tamiya DT-03 chassis. The red anodized finish and aluminum build lower flex versus typical plastic OEM carriers.
Performance overview: swapping to an aluminum carrier reduces unwanted compliance at the rear hub and helps maintain consistent suspension geometry when running more aggressive setups. This yields more repeatable handling during tuning sessions.
Installation summary: remove the rear wheel and original carrier, transfer bearings or pins to the new unit, then bolt the aluminum carrier in place with the original fasteners and the correct hex driver. Check wheel alignment and suspension travel after installation and recheck fastener torque after a short test.
Fitment reminder: intended for DT-03 chassis; confirm dimensions before attempting to fit on different Tamiya platforms. This product is an RC upgrade component, not intended for full-size vehicle use.
