This is an XRAY T4 2017 Graphite Floating Servo Holder. This CNC-machined floating servo holder is made from 3.0mm premium-grade graphite material.
The all-new, unique floating servo holder is now standard in the T4’17. The floating steering system is disconnected from the chassis and works fully independently without affecting flex. This makes the car easier to drive in high-traction conditions, and chassis roll is reduced especially when driving through the curbs. The car also handles better on bumpy tracks.
In combination with XRA302570 Steering Plate, you can adjust 4 different flex characteristics. Using the graphite steering plate, chassis flex is medium; when using the steering plate with aluminum stand, flex becomes stiffer for more aggressive handling and increased steering.
Thanks to the unique design of the servo holder, changing the flex of the steering system is quick & easy. There is no need for other parts, and there is no need to disassemble/reassemble the servo holder.
