Tackle your trailer repair or build project with the right parts from the start. Our 3500LB Trailer Axle U-Bolt Kit is engineered for one job: to provide a supremely strong, corrosion-resistant connection between your axle and leaf springs. Don't let a failed U-bolt compromise your safety on the road—upgrade with a kit built for reliability.
Engineered for a Perfect, Secure Fit
We eliminate the guesswork. This kit is specifically designed for the industry-standard 2-3/8" diameter round axles found on 3500 lb capacity trailers. The included components work together seamlessly to create a clamp force that locks everything in place, preventing axle shift and ensuring stable towing.
Maximum Corrosion Resistance is Standard
Unlike thin, electroplated coatings that quickly wear off, our hot-dip galvanizing process provides a complete shield of zinc over every surface of the U-bolts and plates. This robust barrier is your best defense against rust, ensuring your investment remains solid and reliable for years, even in coastal or winter road conditions.
Durability You Can Depend On
From the steel alloy used in forging to the precise thread machining, every detail is focused on strength. These U-bolts are designed to maintain their clamp load under the constant stress and vibration of highway speeds and rough backroads, protecting your trailer from unexpected downtime.

Boat Trailer Repairs and Maintenance
