any help would be appreciated -

When i bought my tj it came without a rear upper jouncer. I'm just going to order two replacements so they're the same and then be able to judge/measure what increment(s) bump stop extensions i need.

Now, the part where i need you guys. I'm pretty sure to have everything the way it should be i need to look into bump stop extensions. I did the usual googling and seems most people say to stay away from the d*ldo looking things and that what i should get are the hockey puck type discs.

with that being said, what are your thoughts on bottom extensions vs upper extension. I believe i remember seeing a thread where people were saying go with upper extensions but i came across a nifty kit from jks for bottom?

any suggestions for running 3.5 re spring (besides dont run them) for max "useable" travel.
i have not bought shocks or bump stops yet. i have a 1.25" body lift, and will be getting a mml.
i will be running 35" tires.

i have a used set of re 3.5 springs front and rear.
i have currie jj control arms front and rear.
i have a rear teraflex revolver track bar.
i was gonna use the stock front track bar, and re drill the axle mount hole.(i could buy a currie if it will help)
i have re extended braided brake hoses front and rear.
i want to get the teraflex rear upper shock mount that raises the mount location 1"
i would like to move the rear lower shock mounts on to the lower control arm mounts.
i was not planning on moving the front shock mounts.

it all on a 2005 rubicon unlimited sahara.
all suggestions are welcome.
i know re springs dont travel the best, its the rate i want, i tow.

Skip the upper shock mount relocation. Outboarding the rear shocks lets you run a longer shock and puts the shock in a position to dampen better.

i know about outboarding rear shocks, doubt i will go that route.
i can get enough travel with moving the lower mounts, and gaining an inch up top.
its not a desert racer, and will see only mild off road use.
i got a rock buggy to abuse. this is a toy for light use.

Wonderful thread. I definitely have a good idea what I must do to get my bump stops dialed in (the PO had a 4" lift installed and no bump stop adjustment whatsoever). Now, based on other threads I have seen hockey pucks used as bump stops and seeing they are one inch think they would work great as I can add or subtract as needed. My question is regarding attachment. What is best to use (other than a bolt as I don't have a tap and die set). RTV? JB Weld? Elmers Glue? Thanks

Drill, tap and bolt is best option. I've made epoxy work, although make sure it is strong and mix it well before applying.

quick question. I have SOA, CJ7 , Dana30 front. I have 11 1/2" from center to center on front studs for the shocks. How short of a shock should I use to allow for wheel to come up? is a 9 1/2" shock too short, compressed ?

At least 4" uptravel imo....
How did you end up with 11 1/2" on a SOA?

Came upon this thread a few years ago. Wasn't knowledgeable enough to grasp it at the time. While my truth is I'm still not all that savvy to all that's been discussed in here, though I can now appreciate it a lot more. Loved how you handled the moron in the first 5-pages or so, too...

Outstanding thread. Friggin' outstanding.

I am going to resurrect this beast of a thread to get some input. I've read through this at least twice over the last few months and every time I finish, I end up with a throbbing headache. Sorry I don't have a lot of posts, as I generally just search and read and figure it out as needed, but this one blows my mind.

Here goes, '05 TJ X, 2.5" RC lift about 2 years old, 32s on Moabs, no body lift or MML on at this time. She is mostly my DD, some light trails and the snow that has decided to be a SOB this winter.

If I go with the Bilstein shocks for a 3" lift, as shown on Q-tec

Front 24.00/14.88
Rear 22.44/13.98

That would require 1" BSE for the front and 2" for the rear?

Any help would be appreciated.

1.25 front and can be closer to 3" with a 14" collapsed rear length depending on pinion angle.
Pull the springs, install the new shocks then set it down bottoming out the shock, measure the distance from the axle pad to the metal bumpstop cup.
I have never nailed the rear due to variables. I do have a tj in the shop now with 14" collapsed rears in stock mounts, stock upper ca's and 16" re lowers i could measure. I can tell you tho it has 4" extensions currently bolted on it, 2" rear uppers along with 2" lowers that would normally belong on the front, which i had nothing to do with, the dirt line on the shaft comes within a half inch of bottoming out. it came in that way. It has 3.5" re springs, 03 rubi skid pan w/1" t-case drop.

Im pretty sure there are measurements in a photo with ome n66l shocks that are 14" collapsed. Lift height does not matter or even factor into the bumpstop requirements of a collapsed shock length. Use of shock shifters and pinion angle changes do factor into the rear bumpstop requirements.
