The TRF421X 1/10 4WD Electric On-Road Touring Car Kit delivers a competition-focused chassis with a belt driven 4WD layout and refined suspension geometry for enhanced stability, adjustability, and control on high-traction surfaces. Its balanced drivetrain and low center of gravity design support precise handling and consistent performance for serious racers and experienced hobbyists.

About the TRF421X


Suspension

The suspension system on the TRF421X is designed for precise handling, improved traction, and refined control on high grip surfaces. The front and rear suspension arms are molded from carbonreinforced nylon for predictable flex and durability, while updated mounting points shift the damper stays inward for a more responsive feel and better weight transfer during cornering. Shorter, advanced dampers help lower the center of gravity and allow racers to fine tune their setup with spacers and multiple attachment positions for different track conditions.

Chassis

The chassis is made from high-rigidity carbon fiber for balanced weight distribution and predictable handling. Its design combines stiffness and controlled flex to keep the car stable through corners. The aluminum motor mount provides precise alignment while keeping weight low.

Steering

The steering system delivers precise, responsive control for confident cornering. Aluminum knuckle arms provide rigidity and consistent geometry under load, while the adjustable sway bars help fine-tune roll stiffness and balance. Together, these components enhance steering feedback, stability, and overall handling on high-traction tracks.

  • Carbon fiber chassis with optimized stiffness and controlled flex
