Leaf Spring Replacement Qs?

Hello, my leaf springs are completely shot. Is replacement as simple as measuring from mounting bolt to mounting bolt and ordering by that length and number of leaves? Is there a specific brand that folks recommend? My axles are still in good condition, so don't plan on converting over to torsion axles or anything like that at this time. I assume since I have a 10k trailer, each spring should support 2.5k? Any other pro tips?
Thanks in advance.

Do the research to learn what spring you have As the measurement between eyes,types of eyes or slipper type,number in stack,widths.get some new matching ones,u bolts,re- hab the plates etc looks like you could use a nice re-build under there once you start you have to address it all and put new life in her.trailer super store is your friend the oem stuff works too.

Yep, those look bad but at least they're still intact. I'd take the load off one of them and you need two measurements, the distance between the eyes, and the drop (from spring eyes to bottom of the pack). Yes, they need to be no less than 2500lbs each, and get new shackles and bolts and ensure the perch holes are not elongated. If you want to upgrade to torsion axles, i found the best price was at Davis Custom Trailers in Plant City.

No affiliation, but these guys were great to work with when I rebuilt my last trailer. Made in USA!!

Took off one spring today and am going to the trailer supply store a few miles down the road to get the replacement parts to do the job. My Milwuakee high torque cordless impact made quick work of all the seized/rusted bolts. I'm amazed at the power in this thing.

For reference purposes, you can see what your springs should cost. Double Eye Trailer Springs at Champion Trailers
You should use new hardware, brakes and hubs while you're at it.

Use a 50/50 mix of atf and acetone next time. Amazing stuff.

Glad you got it off. Use a 50/50 mix of atf and acetone next time. Amazing stuff. Use a paint brush and mix immediately prior to use.

The u bolts and nuts are all in decent shape... I think I could even reuse them, but I'm not going to.
I went to the trailer store today and they measured my springs at 27". They said they were probably stretched because they were completely shot and said I could go with 26" springs. Of course they didn't have them in stock and the ordering lady was out... I ended up ordering some 2" x 26.5" springs online since that seemed to be the most common for a 5200 lb axle. The springs are open on one end so it seems like their is some allowable play.
