It looks like SpringsNThings no longer sells leaf springs. Surprisingly I cannot find them at all on their website.

Is there another company that we recommend for replacement springs?

I forgot the whole name but there's one out of KC that I've bought them from. Something like "general KC spring". It's been about 3 years since I have bought from them, I've bought them for my 78 fury, my 01 Durango, and my cousin has bought 2 sets for his fleet of Ford rangers.

Disregard - They emailed me back and said they still make springs. Odd they arent listed on the website too.

This place?
generalspringkc.com

Yeah that's it / the one I was thinking about.
Theres another out in (I think) Pa. I've talked to.
I was on the fence about where to get the ones for my 01 Durango, both places listed "HD" option, with same capacity, but the place in Pa had the heavier capacity on 5 leaf (same number of leaves as original springs /and their std duty) general had as a 6 leaf assembly, I got the 6 leaf. I dunno if they used a thicker leaf as the 5th leaf?

I've added a leaf on many of my vehicles, and never had the "lumber wagon effect" on any of them the way I do on this Durango. I've since bought 5 leaf springs for my 78 fury from them to replace the original 4 leafers, and no lumber wagon on that, it actually much better than the originals ever were.
I took those originals off about 10-12 years ago and took them to a spring shop and had them "re arched" and that didn't last a year. I ended up having to buy some air shocks for it and putting them on in a parking lot while we were on power tour that year, with the 5 leaf units and regular shocks it rides so much better than the original 4 leaf + the air shocks.

ESPO website states...Leafs are currently taking 4-5 weeks to ship.

Is there a local spring shop in your area Goddy that could rebuild yours to your specs?

I need to get my front leaf springs rebuilt on my D150. I have used these guys in the past and was happy with their work. https://www.boisespringworks.com/

I've purchased from these guys before: http://www.johnrspring.com/leafsprings.html

They're local, so I just picked the springs up. The probably ship.

I bought new springs from a local shop, At the time I thought I could have saved a bit had I bought them online but with taxes and shipping and duty it might have worked out.
I've had one vehicle where the main spring broke and was replaced locally, and another vehicle that has broken a spring in the pack on either side now which was also fixed locally.

I have heard from more than one person that the site you listed makes all of ESPO's springs anyway, so may as well go straight to the source.

I've used ATS springs in Pennsylvania as mentioned above. Nice quality parts
