The TAMIYA DT03 Aluminum Rear Dogbone by GPM DT3158A is engineered to link the CVD joint and the wheel joint in the drive train with improved rigidity. Where the original plastic posts are prone to deformation or failure, this solid 6061 T6 aluminum component provides a stronger, more consistent connection. The thicker geometry, at a 10mm diameter, increases contact area and reduces flex compared with the stock part, helping maintain alignment and power delivery under load. Supplied in multiple colours, it is a straightforward, high quality upgrade for model builders seeking dependable drivetrain parts.
