The XRay XR302242 X4 Aluminium Hub is a lightweight, CNC-machined steering block crafted from premium Swiss 7075 T6 aluminium. Its ultra-strong construction reduces flex to deliver more consistent handling, particularly on high-grip tracks and in spec racing classes, while offering precise geometry and long-term durability.

Key Features

  • CNC-machined from lightweight Swiss 7075 T6 aluminium for strength and precision
  • Reduced flex for improved, repeatable handling; frees up the car on high-grip surfaces and in spec classes
  • Full axle height adjustability to fine-tune for track and tyre conditions
  • Universal design can be used at all four corners with the corresponding extensions
  • Compatible mounting for carbon front steering plates and rear ARS plates based on hub position
  • Ultra-strong build for extended life in demanding racing conditions

Suggested Compatibility

  • XRay X4 platform; intended as a direct replacement for the standard composite hubs

Installation Note

  • Due to the lower hub height versus the kit composite hubs, add 2.0mm of shimming to achieve the same upper arm height above the hub.

X4 alu steering block CNC-machined from premium lightweight T6 aluminum. Ultra-strong construction provides very long life and durability in even the most extreme racing conditions. Direct replacement for the standard composite hubs. Using the steering blocks in an aluminium material reduces flex, and improves consistency, and will free up the car, mainly for high grip conditions, and especially in spec racing classes.

The hubs allow full adjustability of the axle height to adapt the car to every condition.

The carbon front steering plates and rear ARS plates are easily mounted depending on the hub\'s location.

The design of the hub is universal with the same part used at all four corners with corresponding extensions.

Please note: Because of the lower height compared to kit composite hubs, 2.0mm additional shimming must be used to achieve the same upper arm height above the hub.
