1/10 R/C TRF421 CHASSIS KIT

This R/C model assembly kit creates the 2 belt-driven 4WD TRF421, the latest model in the line of TRF (Tamiya Racing Factory) chassis, which offers a plethora of setup options and easier pit work. Its motor has been moved into an almost central position and drive belts are of equal size, contributing to greater pitching stability on the throttle. A choice of one- and two-piece versions of the upper deck lets you fine-tune your setup, and the refined drivetrain uses a front direct coupling and rear oil-filled gear differential. The suspension uses upper and lower A arms, with the latter employing ball connector mounts; new USBB (ultra-short big bore) dampers are mounted via aluminum stays, and can be further fine-tuned with spacers. A total of four stabilizers (three thicknesses: 1.0mm x1, 1.1mm x2, 1.2mm x1) is included, and countless parts across the chassis have been updated.
