XRay XB2D 26 – Dirt Edition (XR320021)

The XRay XB2D 26 – Dirt Edition (XR320021) delivers the latest XB2 ’26 platform advancements tailored for clay and dirt tracks. Engineered for maximum traction, consistency and control, it combines a short-size 2.5 mm chassis option with dirt-focused geometry to help keep the rear planted and the car responsive through rough sections.

Durability and precision are elevated across the platform thanks to reinforced suspension blocks and hardware, ultra-light titanium links and pivot balls, and reduced-mass driveline parts for quicker punch and sharper braking. Suspension travel and ride height adjustment are broadened for easier tuning across varying surface grip.
