ProPride and lifted 3500
Hi all, We just applied for financing on a 2021 Fuel F-287. Assuming the loan gets approved, we should be picking the unit up on the 18th. I have a 2020 Denali 3500 SRW that I put a 4" suspensio...

Simple method to figure out you lower rating is old diam tire/new diam tire times rear ratio. (32/35)3.73 = 3.41 effective axel ratio.
If you were stock at 31", then you are down to a 3.3 effective ratio.
I'm assuming you have a DMAX with that high of a GCWR. Being as 3.73 is the only ratio, no way to tell where you really are per say now in comparison. SWG about 88% or 26,300 +/-.
Remember gcwr is a performance/warranty rating only. Question becomes, what performance are you looking at etc. Holding 60 in DOD vs OD vs Direct at 1800 rpm......pulling an X% grade with out stalling in 1st gear.

Yes it's a duramax with a 10 speed allison. According to their spec sheet it's actually 3.42. I went from a 33" tire to a 35" tire and it dropped my ratio to 3.22. About a 6% loss. I did some regearing research and I'm not sure a 6% difference is worth it?
SWG about 88% or 26,300 - What is SWG?
I think that trailer is light enough that if I were happy with the performance, I wouldn't bother.
This is sort of what I'm thinking, but I guess I'll just have to see how it performs.
One other question I have is, I currently have a B&W tow and stow that is rated for 1450 VTW and 14,500 trailer weight. I have to drive from Gilbert to Tucson to pick up the trailer and wondering if I can get by with this for the hour and a half drive back without permanently hurting my truck suspension? You know those trucks out there that seem to have perma-sag in the rear end...? I want to avoid that if I can.
I don't necessarily want to spend 3 hours at the dealer trying to install the ProPride in their parking lot.
