This product is a genuine Traxxas steel hex wheel hub set designed to provide maximum strength and secure wheel mounting under high-load conditions. The hardened steel construction offers superior resistance to rounding, wear, and impact damage compared to standard aluminum or composite hubs. These hubs ensure reliable power transfer from the axle to the wheels while maintaining precise fitment. This set is compatible with the Traxxas Unlimited Desert Racer (UDR) and is intended for vehicles using steel hex hub configurations. It is an ideal replacement or upgrade for improved durability and drivetrain reliability during aggressive off-road driving.
