Can 3,500 lb Trailer Axle Springs be Replaced with 4,500 lb to Prevent Sagging

Question:

2022 keystone 287qbs- came with tandem 3500lb axles with 1750lb rated leaf springs 26” long. These springs are already completely flat and it’s never been overloaded. I’m looking to upgrade and be done with this issue. Can I use the 6-leaf 4500lb leaf spring replacements without issue so that I don’t get the saggy leaf spring issue in the future?

Yes, you can upgrade your current leaf springs with the higher rated 4,500 lb part # e27SR and you'll be fine. The suspension might be a little stiffer but you wouldn't have to worry about it going flat like what you have now.
