This product is a complete, ready-to-install Idler Hub Assembly and Axle Kit designed for single-axle trailers with a 2500-lb (approx. 1134 kg) Gross Axle Weight Rating (GAWR). As an "idler" or "non-driven" hub, it is specifically intended for the non-brake axle on a tandem trailer setup or for simple, single-axle utility trailers that do not require braking.
The core of this assembly is the 5-bolt wheel stud pattern with a 4.5-inch Pitch Circle Diameter (PCD), a common standard for many small to mid-size utility trailers, boat trailers, and equipment trailers. This kit typically includes all necessary components to mount a wheel and tire onto a straight trailer axle tube, providing a reliable and durable solution for medium-duty applications.
Complete Kit: Includes hub, bearing, seal, and mounting hardware for easy installation.
Common Bolt Pattern: 5 on 4.5" bolt pattern fits a wide range of standard trailer wheels.
Idler Function: Ideal for the non-brake axle in tandem configurations or for non-braked trailers.
Durability: Designed for a 2500-lb axle rating, ensuring robust performance for its class.
Primary Applications: Utility trailers, boat trailers, small equipment trailers, and landscaping trailers.
