The JR-DT309-RD kit by Jazrider fits the TAMIYA DT-03 chassis and includes an aluminium servo saver plus matching aluminium tie rods. The set uses a 25T servo spline and is engineered to reduce play in steering linkages so inputs are more direct and consistent.
Focus is placed on adjustability and maintaining steering geometry under load rather than changing propulsion. Aluminium construction helps the steering stay true during scale driving, while the 25T spline lines up with commonly used hobby servos. This kit is intended for RC hobby use.
Fitting guidance: attach the components to the DT-03 steering rack, then fine-tune tie rod lengths to achieve neutral toe and equal throw. Centre the servo before locking rod lengths and make measured changes to saver tension and rod length to refine steering balance.
