The GPM XRT190C is a precision-engineered driveshaft manufactured from 4140 medium carbon steel to provide a stronger replacement option for TRAXXAS XRT 8S vehicles. The shaft diameter is upgraded from 5.5mm to 7mm to increase rigidity and reduce driveline deflection, supporting more consistent wheel and tyre rotation under load. This part is intended as a direct replacement for components used with the X-Maxx WideMaxx suspension kit and is suited to demanding running conditions where improved drivetrain durability is required.
