Plushest riding Spring...

[cmb396]

I am looking to upgrade my RC 2.5 spacer to springs for another 1" or so of lift, however, I don't want to sacrafice ride comfort. What springs offer the best on road ride, ie, same as stock or damn close? This JLUR is my wifes, and won't lie, basically a mall crawler, we get on some light trails from time to time, but nothing serious.
I already have Falcon 3.3s, adj front lower control arms, adj front trac bar, and rear trac bar (no brackets).
My buddy just got a gladiator and has the mopar 2" lift with 37s, and the stance looked great! It sits about 3/4-1" higher.

Let me know whats out there, I know it's subjective and everyone has their opinion, but would like to hear them. Thanks.

We have posted our spring rates on here before, I'm sure you can find it in our comment history, our rate at ride height is nearly the same as stock. Tires and shocks will have a great influence as well.

How do you like the ride quality with the Falcon shocks? If you’re planning on keeping them you almost need to find a spring that will play nicely with it.

I had a 2.5” RK lift on my JLR with Falcons 3.3s and even on the softest setting it was apparent they weren’t a great match to the RK spring rates. Switched over to Fox 2.0 shocks and it was a night and day difference in ride/bump compliance.

But, honestly, unless you go long arm and get the suspension geometry angles closer to stock parameters, it will never ride as nice as the factory setup.

TBH, I agree, even on the softest setting, they seem harsh at lower speeds. Anything above 25mph, and they are great. I have not ridden in the Fox 2.0, so I cannot compare. I bought the 3.3s when they were on sale, and iIIRC, the Fox was not avail yet for sale?
I can live with them tho, atleast they look awesome!! lmao

My suspension is dialed in perfectly. Cast is camber is just a touch off from factory settings. The adj lower control arms took care of that. The jeep doesn't wonder at all, and you can drive with your pinky finger at 80 with 37's.

I do have 37 toyo RT (10 ply), on 22" wheels, so I know that factors in. Didn't want an E rated tire for a jeep, but that's all the RT came in at the time, I think they have a C rated tire avail now tho, of course. I'm only running 30lbs in them to help with the ride. Overall, I'd say it's about 90% as smooth as it was stock.

Reading thru another thread atm on your springs and rates!!
Are the lift heights based on a Rubicon or sport/sahara? I have a Rubi, and with the 2.5" spacer, my tires got into the fenders on our last outing at OBX. I also have the AAL led fender lights with inner fender liners removed.

The only company I've ever seen publish spring rates for all their coils is ARB/Old Man Emu. With all the others, it's a crapshoot.

So does Rock Krawler have their spring rates on their website?

Sport - 114/121 Front 171/174 Rear

Rubicon - 123/128 Front 172/176 Rear

Mopar 2" Coils Lift - 131/133 Front 180/182 Rear

Our 2.5" Coil Spring Rates are as follows in the ride zone

137.5 Front at Ride Height

175 Rear at Ride Height

3.5" Coils are already coming in so we will give you those too

140 Front at Ride Height

185 Rear at Ride Height.

Rock Krawler's rates are almost identical to factory. The ride will feel about the same, with a possibility of it being slightly improved since you're taking the spacer out and going back to the coil being seated in the "rubber" isolators both top and bottom.

It should sit about the same as your spacer lift, maybe a tad higher. RK's lift heights on the JL are as stated and are very accurate.

If you decide to give their stuff a shot I will make you a sweet deal on a set of 2.5 coils and spring seats.

on 4 doors they are based on Rubi stock height.

And you list block height and extended length. Pretty important when trying to figure out if you can run 12" and 14" shocks without the springs falling out. But apparently nobody besides you guys thinks that's important.

I can't think of any subject more subjective than "ride comfort" - maybe, which exhaust sounds best. Good luck.

Agree 100% and eluded to in my OP, but wanted to get some ideas, and have done so.

Does your 2.5" lift the front higher to delete factory rake?
