Hey Ted! Thanks for catching that. The Terran Industries 4-Leaf Double Eye Spring # TX58RJ has a capacity of 1,750 lbs per spring. These are designed to work with 3,500 lb axles. If you have a 3,500 lb axle with 25-1/4" leaf springs these will work as a replacement. If you have a different measurement or capacity let me know in the comments and I'll see what else is available.
What kind of trailer do you have?

I have a 5x10 Darkhorse with a single 3000 lb axle. I want to derate the springs after adding shock absorbers. I'd like to try e77SR springs. I have another request in your system. What is the deflection at 2000 lb (1000 per spring) of the e77SR springs? I plan to limit the axle load to 2000 lb (about 1000 lb cargo). I am aware that the e77SR is longer than the original 25-1/4" springs but it looks like they will work OK with 3-1/8" shackles. You list i.43 inches deflection at 2500 lb (1250 per spring) for e66SR springs. It would be nice to know the expected deflection at capacity of the e77SR springs. Thanks, Ted
