XRay T421 Aluminium Flex Chassis 2.0mm - Swiss 7075 T6

The XRay T4'21 Aluminium Flex Chassis 2.0mm is a precision CNC‑machined chassis plate crafted from premium Swiss 7075 T6 aluminium. Designed for typical carpet tracks and high‑traction asphalt, it delivers a balanced flex profile and confident handling under high grip.

Redesigned to work with the T4'21 motor mount and T‑brace, this ultra‑narrow 84mm chassis features strategic cut‑outs to tune flex characteristics across a wide range of traction levels. The mid‑motor layout accommodates a centre drivetrain system, while narrow mounts support long‑arm suspension geometry. The updated layout moves the main bulkheads 1mm towards the centre, and the underside is shaped to minimise ground contact when cornering for improved speed and consistency. Finished in a durable black coating with laser‑engraved detailing, part number XR301006 combines performance with robust construction.
