2400BH Flat Leaf Springs
After purchasing a 2400BH a little over a year ago and pulling it about 6,000 miles last year, I have started preparing for some suspension upgrades. I will upgrade to the 225/75R15 Goodyear Endurance E-rated tires, add the Morryde CRE3000, add the Morryde X-factor crossmember and (I thought) sumo springs. I got under the trailer today to check measurements on the sumo springs and they barely fit in place with NO mounting bracket! My leaf springs are almost flat and a couple are starting to have a hint of a W. I only attached one picture, but all four look pretty similar to this one. I have the 3500# 3" Dexter 4440558 axles, so these should be 1750# springs. I travel very close to the maximum GVWR, so I usually have ~6,800 pounds on these, but they are not overloaded and I didn't have any harsh terrain last year, so I'm not sure why these springs have gone so fast. I'm thinking of moving to a 2,000# rated spring. Any thoughts on that? (I realize my GVWR and axles ratings will remain the same, but I'm really concerned about how quickly these got so flat.) Also, because they are so flat, it's hard to get a good measurement. Anyone with a 2400BH sympathetic enough to measure theirs? Also, any worries about reusing the u-bolts, nuts and plates if I change out these springs?

I can't help you with your issue but I have read on here some members experiencing flat springs due to inferior made in China products being used. These were corrected by going to your local truck and trailer shop to get new leafs at the same rating but superior build. They will also have or make the ubolts you need. For the small extra cost, I'd replace them. Some say that anything that got torqued down shouldn't be reused. Wheels being the exception I guess.

As @Ynot4me2 said, this is not all that uncommon for the OEM leaf springs. I would recommend not going more than a few hundred pounds above the original rating, though. Replacement springs with higher quality steel with be fine and not subject the coach to the extra stresses of being over-sprung and too stiff.

Forgive the newbie question, but what should I be looking for on my 2021, 22MLE with the same miles on her? Although I kind of see the "W" but could that be caused due to the rig not sitting on level ground? From my untrained eye, I do not see anything wrong, but obviously there is.

Are you saying you don't see anything wrong with the OP's photo? If that's it, then those springs should have a definite arch to them, instead of being flat like they are.

No. Surprisingly, there is still 2.5 inches clearance. My trailerr has a thin metal liner above the wheels and there is no indication of contact.

The minimum is 3" according to Dexter's manual.
