Problem-Solving Design & Core Advantages
Targeted Solution for Common UDR Issues: We’ve identified a frequent pain point among Traxxas UDR 1/7 owners—rear axle shaft breakage. This issue is often caused by the weak steel pin that secures the stock hex hub, especially for users who have upgraded to larger, higher-torque motors (which put extra stress on the stock components).
Real-Car-Inspired Spline Structure: To address this, we’ve engineered a spline hub system—mirroring the durable spline designs used in full-size vehicles. Unlike the stock setup, this upgraded system eliminates the need for a cross hole on the shaft (a major weak point in the original design), drastically enhancing overall structural strength.
Premium Materials for Maximum Durability:
Spline Rear Hub: Constructed from high-grade 7075 aluminum alloy, delivering excellent rigidity, wear resistance, and lightweight performance. It retains the stock 17mm hex size for seamless compatibility with existing wheels.
Heavy-Duty (HD) Rear Shaft: Made from 45# steel with professional hardening treatment, ensuring superior toughness, impact resistance, and long-term reliability—even under the increased load of upgraded motors.
Package Inclusion: Sold as a complete pair (2 spline hubs + 2 HD steel rear shafts), providing all the components needed for a full rear axle upgrade on your Traxxas UDR 1/7.
