How to Determine Correct 4,000 lb Trailer Leaf Springs

Question:

To whom it may concern, I am looking for leaf springs for a 2021Keystone Hideout 30BHKSWE. I would like to go with 4000# for the fact that I live in Alaska and we have viscous frost heaves.

I can help you determine the right replacement double-eye leaf springs for your Keystone Hideout, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as all you need to do is measure your current leaf springs from center-to-center of the spring eyes.

Leaf springs also flatten a bit over time, so you should go with ones that measure a bit shorter than what you currently have. For example, if your current leaf springs measure 26-1/4" center eye to center eye go with the 26" leaf springs. Here are all the options we offer for 4,000 lb leaf springs (all lengths are center eye to center eye measurements):

- 26" Long: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles # e22YR

- 26" Long: 4-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - Dacromet # e48SR

- 25-1/4" Long: 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles # e57SR

- 25-1/4" Long: 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles - Dacromet # e93SR

Since you mentioned the Alaskan climate, the dacromet coated option is what I'd go with for the best possible protection against the wet weather.
