On mine the fronts will contact 1.1" before the axle bump stop (just measured). Still not a bad lift for the $$, but i would have bought other shocks if i knew about these issues. Oh well, just another excuse to burn some metal.

What did you have in mind when you say you are going to burn some metal? I am thinking of trying to build some adjustable bumpstops.

On the front i'm going to copy mudb8's idea of using a pipe to extend the shock length. I'll probably go with a little bigger diameter pipe and hopefully 1/4". I'll push it up to about 0.5-0.75" from the hole on the body (to get the impact in for the shock bolt).

Basically i'm going to copy most of what he did in this post.

The rear will get some relocators on the axle (similar to his, or the nth degree kit). I want to build the rear tower too, but taller. I figure if i'm going to do all this cutting and welding i might as well make it so i can have shocks for a 6" lift with NO clearance problems at full droop or compression. I don't plan on a 6" lift, but i never know what i'm going to be getting into in a couple years!

the relocated shock is protected by the lower control arm to an extent, and creats more clearance over all...

rc uses the rubber shock mounted bumpstops to protect the shocks, it's left up to the owner/installer to properly set up the axle bumpstops to prevent damage to the shock mounts and bar pins...

yeah, i figured they would get it right on the second go around, but apparently not.
nth relocates top and bottom...

are your collapsed measurements with the rubber bumper on the shock or minus the 1.5" they are tall?

nth degree shock shifters..

i just ordered mine from jerry on friday, and had no idea about this issue. do you think my kit will come with the 23.5" shocks or 24.9?

and if i run 31's, which bumpstops to i need to lengthen
nothing stupid there.. the stock shock won't get hurt at all. and if you don't need all the flex from the long rc shocks, the stock shocks are the way to go.. 31's don't need any extra bumpstops front or rear, depending on the wheel backspacing they may rub the flares.

IMO, the fronts are pushing being to long, just not enough to make me raise a big stink over.. they only need an extra 1" extension over stock and offer a huge amount of flex in comparison to the stock shocks..

here's my suggestion...

cut off the rc shock mounted rubber stops and add the 1" ,or so, axle mounted bumpstop that is needed to keep the front shock from bottoming out... that'll make a big difference when you find a set of tracks to fly over.

where can you get bump stop extensions? or even better, what can you use to make your own if you cant weld? lots of washers or is there another option?

here's a link

stay away from using the 2" plug in type extensions... they'll get knocked out of the bells up front and can miss the pads both front and rear fully stuffed.

My measurements were eye to eye with the shock pushed up as far as it will go (sitting on their bump stops). I did not subtract out that distance. Thanks for the other tips!

So then the only way to run this lift without damage to the shocks or shock mounts is too extend the bumpstops?

I would say it depends more on the type of terrain your jeep sees and what tire size you are running. If you are constantly flexing it to the fullest you will kill your shocks pretty fast.

I have been running the 3.25 on my LJ For almost 2 months, i dont do anything TO extreme, but love running forest roads and what not. I have not got around to adjusting my bumpstops yet, but am planning on it very soon. I am still running 31's, but as soon as they wear down i am going 33. With 33's i will have to have a larger bumpstop or i will rub at full flex

In this pic i am just barley touching my rubber bumper on the shock, not compressing it yet.

I have the 1.25 bl also, so I am not worried about rubbing at full flex, just wish RC would of mentioned this kinda info on their site for the lift, and also again when they sent out the 'newer and better' shocks that were suppose to fix this problem...

yep extend the stock bumpstops to protect the shocks and mounts, then cut off the rubber bumpers that come on the shocks.

the flexing actually isn't what kills the mounts, it's the bumps and dips in the road that bottoms out the shocks that creates the biggest problems.

you'll need 2" stops up front without a bl, 1" with a 1.25" bl which is about right for the front rc shocks.

the rear just needs to match the shocks, 33's fit and stuff in the rear wheel well with stock bumpstops, although the 24" rc shocks need close to 2.5" extended bumpstops on the rear.

running the 3.25" lift gives you more uptravle and is a closer match to the rc 24" long shocks, I'd still put outboard lower mounts on it to gain more and reduce the amount of bumpstop extensions on the rear.

So, we have to extend the bumpstops 2 inches? That means that this lift gives you more clearance for bigger tires, but because of the extended bumpstops, has the same amount of flex as a stock suspension?

OK.... ya finally figured out what the big stink I was raising is all about! lol

that's exactly right.... same uptravel and bumpstop banging ride tho, flex is improved to the point that's it's not all useable...

question: right now i am running 30's. which bumpstops and by how much do i need to extend?

i plan on 31's in the future, not near future though.

i just ordered 2" bumpstop extensions. is that overkill?

i got them from here:
