Too much Bump stop?

I’m buying a JKUR soon and there is one I am looking at. I had the dealer send me images and it just seems like the bump stops are massive and don’t allow for much compression. Just want to get some opinions from people who may know more than me. I previously owned a YJ and just sold my two door JK and never had to worry about this on them. So look at the image and let me know what you think. Thanks!

Looks like the stock bump stop setup to me....


Wow, I should have done my research first. Thanks!

That’s looks like an AEV lift maybe. It is the bumpstop to their kit. Looks like 4.5 kit judging by that bumpstop.

That doesn’t mean you need that much. Take it out, cycle your suspension. Then measure when your tire hits fender. Add appropriate bumpstop size to not hit fender. Several vendors make adjustable bumpstop kits.

That looks like about 3" of extra bump stop. Bump stops do a few things. They keep the tires from rubbing when the suspension is compressed. They keep the shocks from bottoming. If you have a drag link flip or anything else that would create clearance issues when the suspension compresses they keep that from being a problem.
But that to me looks like a minimal amount of up travel available. Is it a heavy Jeep? Does it have a flipped drag link? I would want to know why it has so much bump stop. It may be that it does not need all that, and running less would give you better suspension compliance. But if it needs all that and you run less, bad things tend to happen.

So I was just informed this Jeep has a 4 inch sky jacker lift kit, which seems to explain the large bump stops.

What would I be looking for in those pictures? Evidence of excess stress?

Torn front driveshaft boot and rear pinion angle (should angle up, almost in line with the shaft. Or hopefully it has aftermarket ones. A pic of the front steering components as well. Looking for a draglink flip, aftermarket trackbar and relocation bracket. (If lacking it will drive a bit wonky)

Just got the pictures. How does this look?

Can I get away with installing an exhaust spacer until I can afford an Adams driveshaft? I’ve been looking at the 1310 extreme duty.

The answer is maybe. Though the spacers are not as easy to install as you would think. Better would be a new crossover pipe which is not that much more than the spacers (like $70). Even then, you might want to fully droop the front suspension and check the clearance. If not enough then add limit straps to prevent it from hitting. Also keep in mind that correcting the caster with control arms will make the angle even sharper so that is why I say maybe. Every jeep is a little different and you never really know till you get under it and start checking stuff out.

Yeah, I was about to bring that up. The tires do not look like they have alot of life. The 4" lift done as is, adds nothing to the value. Parts wise it is $700-900. But, honestly its half done in that form. Aftermarket wheels add nothing to the value as it had decent rims stock. Depending on the mileage for a jku rubicon you are looking at a 24k-32k. 32k being the 30k miles range and 24k being around 100k. Service history can bump that up a bit. Do not get suckered with an extended warranty. Most of those get voided by 5-10% larger tires.

Yeah it has around 45k miles, it’s a 2015. And they are asking around 32k. I may just pass it up though it’s a three hour drive to go look at it and I wanted one that is more stock so I could do the mods myself and do my own build. Yes no sales tax is great until you realize how much you get taxed elsewhere lol.

I just sold my two door (not practical with small kids) and I have been driving around a little Kia really itching for a Jeep. I was thinking I’d find one fast but, it’s best to be picky when you are spending 35k for a vehicle.

If it helps I paid 26k for a 2014 jkur with 80k miles a few months ago. Stock, not offroaded. Also, It would cost about $200 to return that to stock. If all they did to the front was swap the track bar.

Was that private party or dealership? Seems like a pretty good deal from what I’ve been seeing.

Sadly 2014 was one year before 4.10 was standard on a rubicon. Mine is 3.73 but I knew that before I bought it. (Pulled the build sheet. (Thanks jeep for making that easy. You may get bashed... a lot... but that is one thing you did right and it is awesome!)
 
#29 ·
Yeah, I just set up a time to go checkout a different Jeep, mich more reasonable price, private party. But it is 3.73 gears, more reason to go to 4.56 though!

Not a good build... Looks like 4" bump stops to me.

I agree, I will be waiting for a better option. This will be my third Jeep so I’m gonna be patient and find a good deal on one that I have no doubts about.
