The XRAY 305436 low friction Kevlar drive belt is engineered to lift the mechanical efficiency of T4 2020 series RC cars. At 351mm long and 3mm wide, this belt uses high-performance fibres to balance stretch resistance with needed flexibility, cutting friction to improve gearbox efficiency.
Built as thin and elastic as practical, the XRAY Kevlar drive belt lowers internal drag to support steadier power delivery. For best results, keep transmission ball bearings clean and properly lubricated to avoid added resistance.
Specifically matched to the XRAY T4 2020 series (300026, 300027), this belt installs directly on those models and provides a straightforward drivetrain upgrade for racers and club drivers alike.
