The RADTEC 2.0mm Aluminium Main Chassis is built to enhance the Tamiya TRF419 platform with added stiffness and predictable feedback. It is produced to match TRF419 mounting geometry for a straightforward upgrade.
By reducing chassis flex, the thicker aluminium delivers sharper turn-in and steadier mid corner balance. Drivers will find it easier to maintain lines and manage acceleration out of corners.
Despite the increased thickness, the chassis maintains a performance-friendly weight profile. It supports precise setup work and keeps the car responsive to suspension and shock changes.
