The Reflex Racing RSD RX4 chassis conversion kit is designed for Xray’s pre-2014 T4 platform. The kit includes a new 2.25mm thick and only 85mm wide main chassis plate that offers more ground clearance during fast cornering. The chassis sports mounting positions for both regular length and shorty LiPo battery packs and features new captured pivot balls and adjustable plastic insert suspension mounts. Toe angles and track width is adjustable using different inserts and the design of the system does not allow the suspension arm to get loose when clipping curbs or dots, which over a race will allow the car to stay more consistent from beginning to end of the run. The backwards compatible set includes the main chassis, aluminium suspension mounts, a full plastic insert set, front and rear stainless steel hinge pins and hardened steel pivot balls.
