- Compatibility with Heavy-Duty Driveshafts — Designed exclusively for use with the 7750X and 7896 8S-spec heavy-duty driveshafts, this stub axle is engineered to handle the maximum torque output of Traxxas's most powerful brushless powertrains without slipping or premature wear.
- Essential Drivetrain Component — The stub axle is a critical link in your RC monster truck's drivetrain, directly connecting the driveshaft to the wheel hub and transferring rotational power with minimal loss, making it essential for optimal performance and reliability.
- Genuine OEM Spare Part — As an official Traxxas component, this stub axle is manufactured to the same standards as original equipment, ensuring compatibility, durability, and peace of mind when maintaining or upgrading your RC collection.

Technical Performance
The TRX7768 stub axle represents precision engineering at its finest, utilising premium-grade aluminium that delivers an exceptional balance of lightweight construction and structural rigidity. The anodised finish adds approximately 15-25 microns of protective coating, creating a barrier against corrosion, oxidation, and UV degradation that would otherwise compromise performance and appearance over time. This component is engineered specifically for Traxxas X-Maxx series vehicles (including the X-Maxx Belted 4WD Brushless RTR in multiple colours, the X-Maxx Ultimate variants, and the original X-Monster chassis) and compatible XRT models (XRT VXL-8S in multiple colours and XRT Ultimate variants). The stub axle must be used exclusively with the TRX7750X driveshaft and is also compatible with the TRX7896 8S-spec heavy-duty driveshaft, both engineered to handle the extreme torque loads generated by Traxxas's 8S lithium-polymer battery setups. The aluminium construction keeps rotating mass to a minimum, which reduces gyroscopic effects and improves corner responsiveness—a critical advantage in competitive RC racing or technical terrain navigation. The precision-machined bore and spline ensure a zero-tolerance fit with compatible driveshafts, eliminating slippage and ensuring 100% power transfer from your brushless motor and ESC to the wheel hubs.
