The most important thing to match when replacing trailer leaf springs is the weight capacity. Which for a trailer that weighs 3,000 lbs I'd recommend going with 3,700 lb axle springs like # SP-040275 which are 30 inches long. This means you'll need to move out your old hangers wider which we have replacements with # 115706S.

It's hard to see in your picture but is the hanger open on the one side which allows the spring to slide out to the side? It shouldn't be open like that. If you need a replacement hanger we have the #115706S for if you have a 1-3/4 inch wide…

Slipper Springs like #e33SR do not use a bolt and bushing for the open eye end of the spring. It connects directly to the hanger using a slipper spring hanger kit.
