These accessories are packaged separately, with a thick outer box and multi-layer protective design to reduce wear and deformation during transportation.
【How to Measure Your Bolt Pattern】5 lug is from the OUTERMOST point of a hole to the CENTER of another hole. Please measure the size before purchase to avoid delayed repair and replacement due to wrong size.
【Durable Construction & Materials】Constructed from high-quality carbon steel with a black anti-rust coating for enhanced corrosion resistance. The dust cap features a galvanized surface for added protection. High-precision bearings ensure low friction and quiet operation. All included hardware is made from robust steel and rubber components, built for long-term, reliable service on your trailer.
【Easy Installation & Maintenance】Follow the proper installation sequence. For best results when installing dust caps, use a wood block and rubber mallet to avoid damage. We recommend inspecting and repacking the bearings with grease annually or every 3,000 miles. Always check for loose nuts, bearing wear, or seal damage before each trip.
