What is the downside to buying longer springs at the same rate and leaving everything else stock?

If there is no downside, I am wondering why Jeep didn't do this from the factory ..

Longer springs will give you more ride height, but you won't get any additional flex, because the bump stop will still limit up travel, and the stock shock will limit down travel. So if the only goal is to increase ride height and widen that bump stop gap, you could do that.

Edit: As for why not from the factory, the higher caster angle will cause additional wear and tear on various components. I think Jeep did the bare minimum to clear 35s reliably, and chose to sacrifice some off road capability as a a result.

If your ride height is higher and the gap between the bump stops is larger, it seems like you would have to have some more flex if the shocks will compress enough to still hit the bump stops.

If your ride height is higher and the gap between the bump stops is larger, it seems like you would have to have some more flex.

Let's say you have 1 inch of up travel and 6 inches of down travel stock, for a total of 7 inches of travel. If you get 2 inch taller springs, all you do is change where you're suspension is in its travel. You would now have 3 inches of up travel, but only 4 inches of down travel, yielding, still, only 7 inches of total travel.

Edit: It's worth noting that the taller ride height will give you additional clearance underneath, and larger approach, breakover, and departure angles, therefore it can still be a significant improvement for offroad performance, regardless of not actually gaining increased flex.

Well, what your saying is true but if the shock from the factory is capable of 2 inches of up travel but hits the bump stop at 1 inch of up travel and 6 inches of down. Then, if you go to a longer spring which moves the bump stop up .5 inches, you would have 7.5 inches of travel wouldn’t you? I’m a newbie at this so genuinely asking. I personally wouldn’t replace springs just to gain .5 inches. I would do shocks and springs.

Seems like another option would be to go with chopped fenders and shorter bump stops if the stock shocks can handle the up travel.

I think the only thing you might be missing is that when you increase the spring height, you are extending the stock shock that same distance as well, if that makes sense. So yes, the shock now has additional distance to travel up, but it technically lost the same distance of down travel as well.

BTW my plan is do do exactly what you're talking about. Bigger springs and longer shocks. But I'm going to be cheap at first and just do spring spacers, because I don't know what size springs I want yet for the eventual lift I put on it, and you can control the lift height better with the spacers. Fox shocks for me all the way!

Ok, maybe I’m looking at this wrong but I assume that the shock would have a little bit of up travel being stopped by the bump stop. So say the total travel of the shock if it was not on the vehicle was 10 inches and the compressed length of the shock was 20 inches and 30 inches extended. Now on the vehicle it could still extend to 30 inches but because of the bump stop it could only compress to 21 inches. You would then only have travel of 9 inches. If you then removed 1/2 inch of bump stop wouldn’t you have 9.5 inches of travel?

Yes, but only if you remove bumpstop. Changing the springs and widening the bumpstop gap at ride height does not actually make the bumpstop shorter.

XR owners be like - this is the nicest plushest riding Jeep.. And then be bothered by the bump stop stuff.

A low cg, plush spring setup is going to ride well. For increasing flex off road, the tribute has to be paid in terms of one of these
- replace to longer stroke fox shocks, remove bump stop bottom
- add 1" teraflex spring spacer
- replace stock spring with Synergy 1" or Clayton 1.5" springs, remove bottom bump stop

I was wondering if the ride was more comfortable than the standard rubicon??
I kinda like the standard rubicon bounce

I just swapped into XR springs for my regular Rubicon. The ride is the same.

Bottom line guys is:
We put longer bumpstops or extensions on to prevent the bigger tires from hitting the fenders under full flex. All lift kits come with extended bumpstops. The bigger the tire, the more bumpstop you need.
So what’s the problem here? The factory gives you longer bumps stops and everyone wants to cut them off.
I put 2.5” springs and MC RockSport long travel shocks on my XR after installing a steel bumper and winch. I have 4-5” of bumpstop space.

The problem is that a lot of people get the XR thinking they won't need to do anything to it. Things like installing a lift.

Yep. This. This is WHY I bought the XR. Oops.

 

[LLRubylady]

Fir someone like me that doesn’t off road shouldn’t be an issue. But I would hate to hit potholes and feel the bump

Yes but you don’t have to install a full lift, all you need is 2.5” springs most all the other components are there. Shocks are not a problem but they help. Like any stock rig as soon as you put extra weight on it it needs springs anyway.
