Top quality lift under 2 inches

[NachoRuby]

I have a 1.5" spacer lift in front, with a .75" spacer lift in back. It rides better than stock. I think the rubber spacers help to absorb the shock, so maybe that's why. I don't know the science behind it, because I'm far from a suspension expert, but the difference, in a positive way, was immediately noticeable once I got the spacer lift installed.

To put it into perspective though, modern vehicles ride WAY nicer than stuff even just 10 years ago. First world problems. 2", even while changing geometry, is not going to cause a huge negative impact especially considering the control arms have pretty good quality bushings that reduce NVH quite a lot.

The OP should look into the mopar lift. It's right at 2" I believe, and retains the factory ride quality from what many have said.

Why would spacers change the ride? Same exact springs and they are compressed exactly the same because they carry the same weight.
Didn't change my ride any.
Explain the science of keeping the same exact springs and yet having negative impact on ride. Can't make it more harsh, can't make it more soft. Only a spring change can do that.

By “negative impact on the ride” I’m not talking spring harshness. Obviously the spring rate is the same by only adding spacers with the same amount of weight on top of them. When you add distance between the axle and the frame by lifting the jeep with spacers OR springs you are changing the geometry of the axle. Your caster will change which will negatively impact steering potentially inducing things like death wobble. Adding adjustable control arms allows you to correct this geometry to a certain extent. Similarly when you lift the jeep your stock track bar will cause the axle to not be centered left to right which will also negatively impact the ride quality. Nothing I have said has been about springs at all I’m strictly talking geometry.

Believe me I know what this jeep suspension is. I replaced every part of my JKUR suspension, some more than once. Even a Fusion 4x4 track bar and drag link. Installed the JKS geo brackets. IMO better than Rancho. I learned that everyone says it rides great. Great to some must mean like a log wagon. To me the stock Rubicon ride is great. TF says the factory shocks can be used with no shock extensions with anything under 2 inch spacer or spring. I won't need bump stop spacers because the tires don't hit the fenders. I'll add some adj front lower CA's to give me a little more caster. Factory set is 4.5 deg caster is a little low so I'll kick it up to 5.5 for better freeway stability. With under 2 inch lift track bars should not be needed but can be added if they are. I'll check out the Synergy springs. I haven't fallen into the rabbit hole yet but I am looking over the edge.

Exactamundo. The guy at the dealership told me that the ride could be affected, but honestly I haven't noticed a difference at all. I recently drove to Galveston again and the ride was perfect, even in the windy trip down there. I've had no problems at all with the Teraflex leveling kit.

I like that you can adjust the Synergy CA's without removing them. Not sure how strong that is along with the Dual Durometer bushing. The spring rate would be very helpful when adding a camper or front bumper and winch. Added weight could turn a 2 inch lift into a 1 inch lift.

That’s why I look forward to getting my Overland. I dunno why people would want to sacrifice ride quality for a lift, but that’s me…

It's a Jeep thing.

Got out the floor jack and the tape measure. The rear sits only 1.25 inch higher than the front. That's where I want it to allow for weight of gear. Looks like whatever lifting I do to the front I will also do to the rear. The max I want is 2 inches and 1.5 looks perfect to me, front and rear. So I have options of springs, spacers, or a combo. As long as I don't bottom out my shocks with compression I won't need bump stop spacers.
