Made from plain-finish low carbon steel, the brackets are economical choices for replacements or standard builds. The 1-7/16″ top-to-center hole distance helps match common leaf spring layouts, and the 3/16″ thick steel adds modest rigidity for light to mid-weight trailers.
Best for: buyers seeking an affordable, bulk-pack option for rebuilding multiple points on a trailer or equipping a budget-focused project.

Buying Guide: Key Considerations And Comparisons
What type of leaf springs does your trailer use? Most brackets here are designed for 1-3/4″ wide leaf springs or double-eye configurations. Confirm spring width, bolt-hole spacing, and whether your trailer requires bolt-on or weld-on brackets before purchasing.
How will you mount the hangers? Bolt-on hangers are easier for DIY installs and repairs, while weld-on brackets offer stronger, permanent mounting for heavier trailers. Ensure your frame material and welding capability align with the chosen option.
Material and finish matter in marine environments. Galvanized and electro-galvanized finishes resist rust better than plain steel, extending bracket life on boats exposed to moisture and road salt. If your trailer operates near saltwater or frequent rain, prioritize corrosion resistance.
Weight rating and compatibility. While brackets themselves are small components, they must support the trailer’s load. Check your axle and leaf spring rating, and ensure the hanger height, width, and hole spacing align with your existing hardware.
Bulk vs. targeted buys. If you need multiple hangers for a rebuild, bulk packs offer cost efficiency. For single repairs, individual brackets reduce excess inventory and simplify sourcing.
