XB2 2026 Rear Upright Adjustable Aluminium - Extra Lower Position XRAY 323358  [XR-323358]

Adjustable aluminium rear upright with extra-low arm mount

The XRAY 323358 aluminium multi adjustable rear upright adds an extra lower suspension arm mounting point tailored for RC use on the XB2 2026 platform. The lowered arm location shifts the rear roll center downward to help stabilise the rear end and can enable higher cornering speeds on high-traction or smooth surfaces when used with matching setup changes.

Made from CNC-machined aluminium, the upright delivers consistent geometry and the durability expected for frequent adjustments. Laser-engraved arrow marks indicate side and orientation for quick identification during maintenance and setup.

For tuning, the extra-lower mount is useful when traction is high and a firmer rear platform is desired to reduce mid-corner movement. Expect to balance this change with anti-roll bar, shock, and rear toe adjustments to achieve the desired handling.

A focused tuning piece for XB2 2026 setups that need tighter rear control on high-traction tracks, offering a durable, precisely machined option for repeatable suspension tweaks.
