For racers wanting sharper steering feel, the XRAY 362552 Aluminum Servo Saver Pivot Shafts are a targeted upgrade. Specifically matched to the XB4'21 chassis, these shafts use Swiss 7075 T6 aluminum to deliver a strong but lightweight solution. The 5mm longer length adjusts the steering plane for improved tracking.
Swiss 7075 T6 is selected for its superior strength-to-weight ratio, helping the steering assembly resist deformation while keeping unsprung mass low. That makes the XRAY 362552 suitable for hobbyists who expect repeatable steering performance lap after lap.
Manufactured to fit the XB4'21 series, these shafts replace the factory pieces with minimal fuss. The extra length is intended to lift the steering link height, which can be beneficial on both high-grip and mixed-surface tracks.
