The Hot Racing Steel Rear CVD Axles Drive Shafts Set B (HRAGRM288NR) is a heavy-duty drivetrain upgrade for ARRMA Grom platforms. Designed to replace the factory dogbone-style shafts and plastic components, this set delivers stronger, smoother, and more reliable power transfer.
Built from CNC-machined steel, these constant-velocity (CVD) axles are engineered to handle higher torque and reduce wear compared to stock parts. They also include aluminum hex hubs, improving wheel connection and overall drivetrain precision.
This “Set B” version is specifically intended for Grom vehicles using rear suspension B configuration, ensuring proper fitment and geometry. It’s a popular upgrade for drivers pushing their trucks harder with brushless systems or aggressive driving.
