AR JK RUBI

So! Needing opinions on installing coil springs on my JK after installing a rear bumper that weighs 200+ not counting spare tire and the ass end is sagging ,can I get by just installing some JKU coil springs with higher numbers or should I get aftermarket? Not looking to lift just level it out. Thanxs

Could get some spacers or maybe try some higher rates from like a rubi or tow package or something.

. My springs numbers end in. 57 I think some 59 or. 60 would work

Synergy sells different height coils.

Not sure if that will make much a difference then. Try a spacer. Figure out how much sag you are getting

I installed the 3.5" RE lift on mine the springs are stiffer and taller if u could find the rating on them. But I pulled my lawn trailer be fore the in stall and it would squat barley any squat after the install. 2 zero turns on the trailer. But a heavier spring should do the trick. If u can find them if not lift it.

With that much weight You may need a stiffer spring for sure. You could get a set of 60s, airbags and spacer to help control everything.

If he went bags and a spacer would he really need a stiffer coil though? I don't think there is a whole lot of difference between 57 and 60s.

Ok I'm going to install some spacers this weekend and see how that looks and feels but keep my eye's open for some stiffer springs Thanxs for the input

. I talked to a guy from another forum that put the same bumper on his JKU and no Sag, that's my reasoning anyway
