Default Bump stop length - Does this look right?

I decided that the extended front bumpstops that I installed with my 1.75" front coil spacers were too long, because I was bottoming out over dips and speed bumps. It was easy enough to cut off some length, so I did. I was considering cutting even more length off the bumpstops, but I decided that maybe the thing to do was to take it out and flex it to see exactly what I have. So here are the pictures of the results with the Quicker Disconnects disconnected: (see my question below the pics)







The passenger side tire is kind of stuffed I guess, but there is still clearance between the tire and the fender. The tire cannot be any more stuffed though, because the bumpstop is resting on the pad. Now I should probably note that I am running stock size tires--32" MT's. I suppose if I had 33" tires, I would need some of the clearance that I have. But given my setup, does it look like my bumpstops are still too long and limiting my travel, or do they look about right to keep from over-compressing the coils?

They look about right to me. You should also be aware that if you still have factory bump stops, they will squash down as more force is applied to them so you do want a bit of extra room to accomodate it. If you do not have the factory bump stops, I would say that you could technically cut off more but would be cautious about doing it if these new stops were provided with your lift as they are most likely designed to prevent over-compression of the new coils as you've already guessed.

I'm runing a 2 in lift, with stock bumpstops. The only thing I have a problem with Is I get a bit of rubing When I'm stuffed and turning.

What size tires are you running and what kind of lift do you have? If you install bump stop extensions, you will most likely not have any more rubbing. Also, they will help prevent your coils from getting over-compressed.

I have the Daystar bumpstops, so they are firmer than the stock ones. I ordered the bumpstops seperately from the coil spacers, so they may have sent me the wrong length. I trust your judgement, so I probably won't cut any more off, unless I have issues bottoming out. I definitely don't want to over compress my coils!

I'm runing 33 13.0 with a 2in superlift block (soon to be upgraded). and yes I am aware of the over compensation problem, but if I put the ones in that came with the lift than I loose about 1 1/2 of articulation. Thats a sacrafice I'm just not willing to make.

(when I get my new lift I will use the 2in Bumpstops on the 3in lift)

I'm not sure if I understand what you are saying. If you are aware of the problems over compressing your coils can cause, why would you care about loosing 1-1/2" of stuff? You may have more stuff now but by not having your bumpstop extensions installed, you will most likely cause your coils to loose their original height. Same holds true if you go 3" and only install the 2" bumpstops and most suspension manufacturers clearly state in their instructions that they will not warranty your lift if you do not have them installed and for a good reason.

Yes but springs are cheap and I would rather have more articulation. Just my opinion for my jeep. I like being able to show up guys with 35's and lockers!!!
