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

Sturdy Composite Uprights for XB8 Performance

The XRAY XB8 Composite Rear Upright gives racers a tougher rear hub solution without sacrificing setup versatility. Outfitted with larger 8x16x5mm ball bearings, these uprights resist wear and maintain consistent rear behaviour during race weekends.

Multiple Roll-Centre Positions

A selectable lower roll-centre position expands your chassis setup range and helps you balance turn-in and mid-corner stability based on surface grip and tyre choice.

One-Piece Fit for Both Sides

The uprights are mirrored in design so the same part fits left or right, simplifying spares and reducing pitboard confusion. Two shims on the lower pin allow small wheelbase and weight distribution tweaks.

Tuneable Geometry for Handling Control

Integrated geometry options cover camber settings, both roll centers, and wheelbase, enabling precise adjustments to suit your driving approach and circuit demands.
