got them from Kolak here on JF!

I run them with about 1.5" bump stop extension (front and rear) and ~3" lift ... gives me nice ~5.5" up and ~4.5" down in the front ... In the rear plenty up as well...

Attachment 591962

Attachment 591959

so far I like them ... and I came from the OME N66/N67 fraction.
The fronts are a good inch longer than the 5100's. What trackbar/diff cover setup are you running?

shorter compressed length and longer expanded for the front, yes.

In the front I am running the stock D30 diff cover, a ZJ V8 tie rod ... and still my teraflex adjustable track bar ... the currie TJS is ready on the shelf, did not get to it yet(and the tera is still good).

I used to have slight diff cover rub at full bump with the teraflex when I was running NO additional bump stop extension, but since I have the prothanes with inner 1.5" hard core there are no fresh marks on the cover (the old ones corroded red)

I found the Teraflex track bar to need about 4" of bumpstop extension.

hehe ... ok ... so I will go out tomorrow to take some measurements ... upper and lower control arm lengths and take some pics ...
thanks!

(okok ... time for the tjs ... no need to prove anything .. but some guys here run the teraflex tb with 2"lifts and no diff contact marks at all and certainly without 4" bs extensions)

Hi everyone I am a little bit of a noob when it comes to bumpstop lengths and I need some help so please try to bear with me. Here is what I am running. 2" BB on stock Rubi coils, 1.25" BL (w/mml), 33x12.50 Duratracs, 2" Bumpstop extentions, and Bilstein 5100s for 0-2" of lift. Here are the specs for the shocks.

Front:
Collapsed Length (IN): 13.06
Extended Length (IN): 21.18
Travel Length (IN): 8.12

Rear:
Collapsed Length (IN): 12.81
Extended Length (IN): 20.08
Travel Length (IN): 7.27

I am heading to the auto hobby shop on base this Friday to install my ZJ Tie rod and new filler hose so I would like to correct my bumpstops while I am there with all of their tools.

2" bumpstop extensions front and rear? if so, you're fine.

but keep in mind, since it's a BB, there is no uptravel improvement over stock, and slightly less overall travel than stock due to the shock lengths. it's fine for going to the mall and "lookin' tough" with 33s though.

I have been pretty capable off road as well. I don't need a ridiculous amount of travel for the trails I hit. Would I be able to use 3" springs eventually or would I need new shocks too?

swap out the BB for 3" springs. longer shocks in front would help. get an alignment, adjust caster as necessary w/ lower control arms. check for longer brake lines.

I plan on doing all of that in the next few months. I start active duty in July so I will finally be getting paid. Thanks a lot for your help.

Ok so comming from a YJ now to a TJ I am new to all this stuff. I am looking at the Savvy/Currie 3" or 4" lift with the AR and a 1-1.25" BL and to run 35's. The more I read the more I get confused. Some say you can run 35's w/ a 3" lift and a BL and others say I must have a least a 4" w/ a BL to clear 35's. I don't want to just be able to clear 35's on the street but on the trails with capable rig with articulation "is that a YJ thing". So if I use the 3" lift and I going to have some much BS that the tires have no place to go.

So does that mean the front is a 9" travel shock and the rear a 8"? Seems a bit short. I was talking to Imped and he recommended 5" up/down on stock mounts. Obviously I would need a 10" shock for that.

I've been doing some thinking...

8.5" of travel with 4.75" of up travel and 3.5" of down travel is the best I can do on stock mounts right? If I moved to a 10" shock I would loose all the up travel I have now. So the only way to get better travel is to move the mounts around?

it depends how fancy you want to get. but ~5" up/~4" down is not bad at all. but yea, if you want more travel, with a longer shock, you'll need more bumpstop extension. with stock mounts, that usually means more lift too.

Yea it's not bad. I like the amount of travel the front has. The rear could use a bit more but I would lose up travel. I'll hopefully link and outboard by the end of the year so I'm not too worried about it.
