I get what you're saying, but seems to me you're talking about travel and not clearance. Maybe you're just defining "clearance" differently than I am, and then again maybe I'm just wrong. Consider the top of his tire as a fixed point and measure to the fender. Now add a 1" spacer. You've raised the fender 1" and have therefore increased clearance between the fender and the tire. I call that increasing the clearance. You've also increased the clearance at ride height underneath the vehicle pretty much everywhere except the axles.
I understand what you're saying. He won't be increasing his travel any because he's still limited by his bumpstops (or fender in this case) at full stuff, and by his shocks at full droop. However, I would say he is increasing his clearance, even if only at ride height. Now, going back to what the OP said. He specifically stated that "he does not want to trim his fenders or get a body lift." I paraphrased there a little. What he has implied is that right now his tires will rub his fenders as the suspension compresses. I've said what I have to say on this topic. It is one that for reasons I don't quite understand, creates a mental block for some people. So, assuming the OPs issue is that his tires are hitting his fenders, I'll turn it over to you to tell him if adding the spacers will solve the issue. |
I'm not arguing here but I probably have that mental handicap too. Pun intended... But I'm wondering if he would at least increase belly clearance? On the other note, I would really like to understand what your talking about. Could you point me in the right direction or video please. Im probably going to re read dirtman's thoughts on lifts again. Thanks

Invest2m4 is correct in adding spacers only changes static ride height, so in the driveway with the jeep in park you will see a height gain and clearance between the fender gain. When wheeling adding the spacer will not limit up-travel (which seems to be the ops actual issue) unless the coil is at full bind which is likely not the case. So the op can add spacers to regain lost ride height but will still need to extend bump stops to eliminate rubbing/contact issues. He will still rub during up-travel....

What I am saying is that using more lift to clear larger tires is in most cases, total BS. Now, that does not hold true in 100% of scenarios. For example, someone going from no lift to a 2.5" lift could clear larger tires without sacrificing travel. Why? Assume that the person adds 2" of bump stop, but also adds longer shocks. In that case, travel was maintained (you are shifting the y-axis down 2"). In most cases, the taller lift has the same shocks. Look at any of the off-the-shelf kits. Compare the 2.5" to the 3.5". The shocks are the same. Therefore, unless you add more bump stop to the 3.5" lift, you don't gain tire clearance. To paint a picture, imagine a Jeep on a lift with the axles fully drooped. The axles can't go any further down because the shocks are fully extended. Let's assume they are the shocks that came with the Boulder Krawler 2.5" lift. Looking from the side of the Jeep, draw a straight line up from the bump stop pad on the axle to the bump stop. That is your Y-axis. Now, upgrade to the Boulder Krawler 3.5" kit. What do you get? Coils that make your Jeep sit an 1" higher at ride height. Shocks are the same, bump stops are the same. What did you gain? As you pointed out, you do gain belly clearance from a static perspective. So, in that case the only way to change the y-axis is to add or remove bump stop, install longer or shorter shocks... or, for a more custom build, move the mounting points. |

No clue if you understand. You are talking about "visual/aesthetic" clearance, not functional clearance. Whether he adds the spacer or not, when he goes over train tracks, he will have the same issue he does today. He could put a 2" spacer and it would still happen. Regardless, gaining clearance at ride height obviously provides no actual benefit since clearance issues happen the more the suspension is compressed.
Now, going back to what the OP said. He specifically stated that "he does not want to trim his fenders or get a body lift." I paraphrased there a little. What he has implied is that right now his tires will rub his fenders as the suspension compresses. I've said what I have to say on this topic. It is one that for reasons I don't quite understand, creates a mental block for some people. So, assuming the OPs issue is that his tires are hitting his fenders, I'll turn it over to you to tell him if adding the spacers will solve the issue. All the guy asked was if he could add 3/4" spacers to add more clearance, and he asked if he needed to run different size spacers to "keep it level". Since uses the term "keep it level", I think it's safe to say that the Jeep is already currently level, so there should be no reason to run different size spacers front and back. By your own admission you're making an assumption that he's having rubbing issues. All he said was that he wanted additional clearance, and he said he didn't want to trim fenders or add body lift. He could very well just want the appearance of more space in the fender wells. I have the exact same lift and RK recommends 2" of bump stop with that lift for 35's. I guess I'm making an assumption as well in that he went with RK's recommendations and is already running the proper bumpstop to avoid fender rubbing, and that all he's really asking for is additional height for a more balanced look overall. Again, I don't disagree with anything you're saying. I'm just saying I think you're jumping to conclusions about the OP's actual issue, and you're using the term "clearance" in a different way than I am. I'm just trying to answer his/her question. |

It's all good, I'm over it. It's not a mental block. I know exacxtly what you're saying, and again it seems your using the term "clearance" one way and I'm using it another.

Chris has plenty of belly clearance with those 37's lol. |
