Overview

Please Note:

This kit comes without an ESC, Motor, Servo, Battery, Charger, Transmitter or Body Shell.

The Tamiya Racing Factory (TRF) 4WD TRF421 chassis kit is designed for racing enthusiasts who crave ultimate adjustability and easy maintenance. The motor's central position and equal-length drive belts enhance stability during acceleration, while one- or two-piece upper deck options allow for fine-tuned setups. A refined drivetrain combines front direct coupling with a rear oil-filled gear differential for optimal power distribution. The suspension employs upper and lower suspension arms, with innovative USBB dampers mounted on aluminium stays for precise tuning. Four stabilisers and numerous updated parts further contribute to the TRF421's exceptional performance potential.

Note

Body, motor, wheels, tyres, R/C equipment, battery pack and charger are sold separately.
