Max tow springs

[Gren71]

Im seeing a bit more sag than id like with my max tow springs. So i thought id just see what springs are on the replacement parts site and make sure i have the right number.

accept there are 25 different rear springs on the site

https://parts.moparonlineparts.com/...s/rear-suspension--rear-suspension-and-cradle


so my question is two fold.
A) what are the max tow spring part numbers?
B) is there a difference in all the JTMT springs? As in are 2020 model springs more or less stiff than 2021 springs?

anyone? If anyone is willing to hop under their JTMT and just snap a picture of their spring numbers that would be a phenomenal help..and a start for me down this rabbit hole.

I recommend throwing a set of airbags in the coils as well.

im kinda being my own guinea pig here.

just a wdh

e2 wdh w/sumo spring bump stops

im going to install the sumo spring inserts tonight or tomorrow and take another pic.

then probably end up putting the bags in. I figured id do it in stages so i can give a kinda scientific approach to what had what effect on it.

so far the e2 wdh w/sumo springs bump stops was pretty dang nice. Rode level and was actually just pleasant.

Haven’t heard of the Sumo Springs before. I’ve always had good luck with the bags and never looked into it further! Interesting......

BTW, how big is your camper? I’m towing a 27 footer.

Installed the airbags today HUGE improvement. The combo of the sumo spring bump stops and the bags makes the JT pull like a dream.

The last picture looks like the travel trailer is still sitting on the block. Its not, I just hadn’t raised it all the way up yet..but its fully on the JT.
