XRAY 369706 XB4 Alpha 4 Lightweight Body - Race-Tuned Shell  [XR-369706]

Alpha 4 Lightweight Body Built for Sharper XB4 Handling

The XRAY 369706 XB4 Alpha 4 Lightweight Body is a purpose-built polycarbonate shell made to lift the performance of the XB4 chassis. Its lightweight outline helps reduce mass while preserving the aerodynamic shape needed for tight racing lines.

Chassis-Friendly Shape for Improved Cornering

The reworked profile concentrates on handling gains by sharpening steering response and raising mid-corner stability. The low profile trims excess weight to reduce roll and aid quicker direction changes. A pronounced front downforce zone and upper side downforce sections help stabilise the car through jumps and aggressive transitions.

Aerodynamic Flow Channels and Thickness Choices

The Alpha 4 includes smooth upper flow channels to manage airflow cleanly over the body, supporting consistent balance on a variety of track surfaces. Multiple material thicknesses are available so racers can select a stiffer or lighter shell to match their setup and grip level.

For competitive hobbyists focusing on aerodynamics and handling, the XRAY Alpha 4 Lightweight Body provides a tunable option to sharpen an XB4's on-track manners.
