Question:

Can you please tell me the correct center of eye to eye on leaf springs for a 2020 Keystone Alpine 3801FK. I have two 7000 lb axles but would love to put 4000 lb springs on rig if possible. I bought new MorRyde Alltrek 4000 from etrailer now I need good leaf springs . Thank you very much

Expert Reply:

According to my research your 2020 Keystone Alpine 3801FK should be using 26" leaf springs so the following will work with your setup:

- 4K Powder Coat # e22YR
- 4K Dacromet # e48SR

The powder coat option will be the same type of finish your current leaf springs have while the Dacromet finish has superior resistance. The Dacromet is better for boat applications but there isn't any harm in adding them to a standard setup either.

I do recommend verifying this length is correct with your Alpine prior to ordering by lifting your trailer by the frame and measuring the center eye distances as well.
