Rubi Suspension on a High Altitude? (Looking to gain 1-1.5”)

[Wheelin98TJ]

got it thanks, I thought a 1” puck in front would work with that 2” mopar lift?

Thoughts on this set up instead? 2.5” RC spacer in front and 3/4” spacer in rear with some added Lower control arms and an adjustable track bar? Or is that not needed?

Thanks

A small 1/2" or 1" coil spacer can work with the Mopar kit. I wouldn't go any taller.

Not a bad alternative setup with those parts you have listed. I'd go with a different track bar though.

For 2.5" of lift in the front, you ideally need an adjustable track bar to get the axle centered. You could go without and run with the axle off center. It won't cause issues other than how it looks.

And you need arms or brackets for 2.5" of lift in the front. Otherwise your caster will be too low and you'll have steering wander.

Also, when you add a 1" spring spacer to compensate for extra weight, like a steel bumper and / or winch, that really isn't the same as running an extra 1" of lift.
The same applies if you are using that 1" spacer to level the stance out.
An extra 1" of ride height up front is not the same thing as an extra inch of lift.

An adjustable front track bar should allow you to center the front axle side to side. A rear trackbar bracket should do the same for the rear axle, as well as improve the geometry of the rear track bar.

I am not a fan of cheap suspension. The suspension determines how your Jeep will ride / drive. But everyone needs to do what they think is right.

thanks, yeah I just want to do what’s best for my jeep and what I think will look good also.

there’s so many options and ways to go about it, I’m getting a bit overwhelmed.

Just for reference, this is a Rubi with roughly 3.5 inches of lift on 35's. Theres also plenty of other photos in this thread.

I too was worried about 35's looking too small, but found it was not the case at all.

Additionally, a Rubi swap sounds great, but in all honesty the Rubi suspension is not that great.

I I freaking love that . I am moving to 3.5" this year . After seeing your I was sold .

That's a good point. It's not really more lift, it's restoring the lift to what it normally is without the extra weight.

Using a spacer to level vs. using a spacer to regain lost height, I consider that to be different. If you're adding a spacer to level, you are adding lift. There is no lost lift from weight to offset the lift you are adding.

Adding a spacer to level out the stance with a 2" lift is no more adding lift then adding a spacer to level out the stance at stock height. A leveling kit is not a lift, whether you are at stock height or running the Mopar 2" lift.
The range of suspension travel doesn't change with a leveling kit, adding a spacer doesn't change the suspension travel overall. It only adjusts where in that range the vehicle rides at ride height. As long as you stay in the correct part of the suspension travel, you are fine. Running a 1" spacer is only going to make it sit 1" higher within that range of travel. That just isn't going to make a big difference to caster, especially if you are only adding the 1" spacer to the front, as it is tilting the Jeep back slightly as it levels it.
That said, adding a 1" spacer to the front to level a lift is very different then adding 1" spacers to all four corners, or even more extreme adding 2" spacers to all four corners. Running spacers like that is more complicated. It can be done, but needs to be considered more like adding additional lift.

We are on the same page, I agree with your points. Small spacers are fine, taller spacers can bring more issues.

I consider a leveling kit a "lift", but that's just minor semantics.

I think all the bolded above are synonymous with "lift".

@vivare you saying that the HIGH altitude isnt High ? Is it same stance as sport ? Or same as Willy’s. IMHO Go with a spring based lift . Save your money up and buy all at one or do like I did . Cleaned a place out in thd garage and then just ordered one piece at a time till I had it all.. shocks being last thing I ordered. Then when I had it all I called Uncle and said hey and we spent 2 days ( total 8.5 hrs. Combined ) and slapped it all on the truck. My real other piece of advise it to make sure you have good jack stands.( I suggest 6 ton jack stands from Harbor freight.) The last thing anyone wants is getting gurt or killed trying to upgrade your ride. And a couple nice floor jacks also.

Just an FYI, the rubicon suspension doesn’t provide any lift over other suspensions. The “factory lift” is an illusion created by the 33” tires and hi-line fenders.
