XRAY XB8 Composite Rear Upright - 1/8 Scale Racing Upgrade  [XR-353354]

Long Life Rear Uprights for the XB8

The XRAY XB8 Composite Rear Upright is built for racers who demand reliability and consistent performance. Fitted with larger 8x16x5mm ball bearings, these uprights deliver increased toughness and longer service intervals without altering the car's core geometry.

Roll-Centre Options for Track Changes

These uprights include an extra lower roll-center position to expand your setup choices. That added position helps you dial handling balance when switching between low-grip and high-grip surfaces.

Same Part for Left and Right Sides

The design allows the upright to be used on either side of the car, cutting spares complexity and simplifying pit repairs. The lower suspension pin ships with two shims so you can tweak wheelbase quickly for different cornering preferences.

Precision Geometry Tuning

Integrated geometry adjustments let you alter camber settings, upper and lower roll centers, and wheelbase. These options allow precise tuning to match driving style and track conditions.
