Its balanced drivetrain and low center of gravity design support precise handling and consistent performance for serious racers and experienced hobbyists.\u003c\/p\u003e\n\u003ch3\u003eAbout the TRF421X\u003c\/h3\u003e\n\u003cbr\u003e\n\u003ch4\u003eSuspension\u003c\/h4\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eChassis\u003c\/h4\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eSteering\u003c\/h4\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"product-page-features\"\u003e\n\u003cli\u003eCarbon fiber chassis with optimized stiffness and controlled flex\u003c\/li\u003e\n\u003cli\u003eBelt-driven 4WD system for smooth, efficient power delivery\u003c\/li\u003e\n\u003cli\u003eAluminum motor mount with adjustable positions for tuning\u003c\/li\u003e\n\u003cli\u003eAluminum knuckle arms feature uptaded hole positions\u003c\/li\u003e\n\u003cli\u003eUpdated upper arm mounts feature 1mm narrower pivot attachment width\u003c\/li\u003e\n\u003cli\u003eUpdated front double cardan drive\/joint shaft\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"_description-right\"\u003e\n\u003ch3\u003eIncludes:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) TRF421X 1\/10 4WD Electric On-Road Touring Car Kit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eNeeded To Complete:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(1) 2-Channel Radio System\u003c\/li\u003e\n\u003cli\u003e(1) Low-Profile Steering Servo\u003c\/li\u003e\n\u003cli\u003e(1) 2S LiPo battery and Compatible battery charger\u003c\/li\u003e\n\u003cli\u003e(1) 1\/10 540 Motor\u003c\/li\u003e\n\u003cli\u003e(1) 1\/10 ESC (Electronic Speed Control)\u003c\/li\u003e\n\u003cli\u003eWheels and Tires\u003c\/li\u003e\n\u003cli\u003eBody and Polycarbonate Paint\u003c\/li\u003e\n\u003cli\u003eTools for assembly\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications:\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eScale Size\u003c\/th\u003e\n\u003ctd\u003e1:10\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTerrain\u003c\/th\u003e\n\u003ctd\u003eOn-Road\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eBody Style\u003c\/th\u003e\n\u003ctd\u003eTouring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDrive\u003c\/th\u003e\n\u003ctd\u003eAWD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWidth\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eLength\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eHeight\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWheelbase\u003c\/th\u003e\n\u003ctd\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Source\u003c\/th\u003e\n\u003ctd\u003eElectric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eAssembly Level\u003c\/th\u003e\n\u003ctd\u003eKit*\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp class=\"spec-fine-print\"\u003e*Tech Note: RC Kits are unassembled Remote Control Models that require assembly, electronics, and other provided items.
