Question:
We have a 2011 Montana 3585SA fifth wheel and i am looking at replacing the springs and hardware. I would like to know what information would be needed that I can provide so as when i have the wheels removed i can have the springs and hardware available so i can do the replacement. Any help would be greatly appreciated.

Hey Brian! To find the right replacement parts you will need to know your axle capacity and grab some measurements. The replacement springs will match up to your axle capacity which can be found on the axle tag. To measure, you can use the flat measurement which will be the most accurate. I linked an article further down on this page which explains how to measure.
For hardware, I recommend upgrading to the MORryde Suspension Upgrade Kit for Tandem Axle Trailers. This comes with wet bolts, bronze bushings, and 1/2" thick shackles. The correct kit depends on your shackle strap measurement (center hole to center hole). If you have 2-1/4" shackles you need # MR46ZR and for 3-1/8" # MR76ZR.
If you can add the capacity and measurements in the comments below I will help you find the parts you need.

WE installed the MORryde wet bolt, heavy duty shackles and their equalizers on our Reflection 315. We have been happy with the ride and we have come across so bumpy roads. We also like the greaseable shackles.We believe that will help lengthen their life..
