This is a front upright set for strengthening the Tamiya TT-02's standard suspension. The original parts are made of resin and lack strength. When modifying for increased suspension stroke, stress is applied, and the axles can easily break (see photo). Also, modifying the suspension arms to increase steering angle is troublesome. These aluminum uprights increase strength and will not break. They also reduce the need for difficult cutting modifications for increased suspension stroke and steering angle. Low-friction suspension balls and aluminum spacers are also included. These are not sold individually. Only 4 sets are available for the first run. RC Shop K
