Features to know about

Solid Mount for Heavy Loads: Galvanized Plate Locks the Axle Down

A loose axle can throw your whole setup off. This formed U-bolt plate gives it a firm hold, securing a 3" diameter axle to a 1-3/4" wide leaf spring. It works as a key part of the suspension system, using (2) 1/2" diameter U-bolts (sold separately) to clamp everything tight so the connection stays solid mile after mile.

Built to Beat Rust: Hot-Dipped Galvanized Steel Keeps it Protected

Road spray and salt are hard on metal, but this plate is built for it. The galvanized steel is hot-dipped in zinc after forming, creating a coating that’s about 3 to 5 mil thick. That full-coverage layer resists rust and corrosion so the plate holds strong and keeps looking good even after years around water and rough weather.

Sized Right for Easy Fit: Accurate Hole Spacing and Dimensions

No guesswork needed when lining it up. The plate measures 5-3/8" long overall with 3-5/8" between hole centers, and 3-3/4" wide with 2-3/8" between hole centers. The bolt holes are 9/16" diameter to match standard suspension hardware. Everything lines up cleanly so your axle and springs mount square and stay aligned.

Reliable Strength for Demanding Use: Works on Trailers up to 7,000 lbs

Whether it’s carrying heavy gear or just logging lots of miles, this plate is built for duty. It’s made for round 3" axles in the 5,200 lb to 7,000 lb range, giving you the solid strength needed for heavy loads on boat or snowmobile trailers that see real-world use.
