XRAY 306519 - 27.5MM Aluminium Top Deck Post  [XR-306519]

Chassis Link Post

The XRAY 306519 aluminium post is an RC chassis component that links the top deck with the chassis plate to create a firmer structural connection. The nominal 27.5MM length stated in the product name is intended to limit chassis twist that can negatively affect handling at higher speed.

Fitting is generally straightforward on compatible configurations where the top deck and chassis plate are fastened with posts or spacers. The part replaces or supplements the existing connector point to tune torsional stiffness and uses the model's standard fasteners rather than any special tools. It operates as a direct mechanical link and is not adjustable electronically.

As a tuning item the post adjusts chassis rigidity: increasing stiffness often raises high-speed stability and reduces rotation when off-throttle, but final setup should be balanced with suspension and weight distribution changes. This component is meant only for RC vehicle chassis tuning and not for full-scale use.
