This product is a Light-Duty Stub Spindle designed specifically for the demanding yet small-scale needs of agricultural and all-terrain vehicle (ATV) trailers. These axles are the critical linkage component that connects the trailer's wheels and hubs to the axle beam, enabling smooth rotation and reliable load-bearing.
Built for robustness and simplicity, this stub axle is ideal for utility trailers used in farming, homesteading, hunting, and landscaping applications. It is commonly used on small single-axle trailers that transport equipment, feed, firewood, or small livestock. Its design prioritizes strength-to-weight ratio and compatibility with standard, easy-to-source bearing and hub assemblies.
