Hi All
i'm new so be gentle! last year i bought a 2016 Wrangler, heavy duty, yada yada. i really hate the ride...way way to hard, changed the shocks to Rancho 9000, it's better but i'm looking for advice on changing the springs. I've read hundreds of threads, I have 14AC on the pass side (not sure on the driver side but assuming 13AC). Not sure what AC means but from what i've read, it's not important. I'd like to replace with same length springs but with a lower spring rate...ya i know, you're thinking why do that? i'm different, hey i work for the Cable Company, what did you expect!!! Keep in mind that i will NEVER go off road with this one anyway, maybe later. Am i to asssume the lower number means shorter coils based on what i have read but what number refers to a smaller spring rate?

You'd be better off getting someone's worn out coils than trying to buy a set of 12's for the front....but yes, lower number, lower load rating.

You mentioned changing shocks but did you also check your tires and the tire pressure? People tend to put heavy truck tires on these lightweight jeeps and the ride suffers.

 

I did try lowering the tire pressure and that helped a lot except it made my fuel consumption abysmal. My shock replacement did help but not to the tune of 1000 bucks which it cost me. So back to my original question if a lower number means a lower spring rate how can I get a lower number with the same length of spring. ?

 

They won't be the same length, but you won't lose much in height. Somewhere on am an older phone I've got pictures of various coils by each other and you can see the length difference but it translates to very little on the vehicle.

You mentioned tire pressure but what tires are you running? If they're a P tire then they'll be soft and usually the stock tires aren't bad. If you start moving up to stiffer sidewall tires then you'll feel a ride difference. Tire pressure drops will absolutely hit you in the pocket with MPG drains but it's about finding what's comfortable for you.
