According to my measurements this will work well I will know by friday.
Front's will need ~3.5" bumpstop extension mounted to the lower spring pad (17" compressed length).

Rear's will be a whole different ball game. Mathematically, it says ~5" bumpstop extension (17" compressed length)...but the horrible spring pad alignment will change things. Unless you've relocated the rear upper spring perch, which at your lift height is a bit of a necessity. The shock mounts should also be relocated & at least outboarded on the lowers. That would help quite a bit.

once again, this all boils down to you needing to cycle both front and rear axles to properly setup your suspension.

I appreciate your advise, Im sorry im not up to your level of jeep suspension geometry but I'm 3 months deep in my first jeep project.

yes spending hours upon hours in the garage is a great way to gain knowledge but I do not have that kind of time, with owning my company I'm lucky to see 2-3 hrs of garage time per week so I have to do all my homework before.

so please in the future save the grief for those that have tons of time but still waste everyone time on here with questions that have been answered 50 times before.

I did so last night this is what i have come up with

Front 24-185943 11" travel

Rear 33-104652 11" travel

According to my measurements this will work well I will know by friday.

Thanks everyone for your help.

so 14 inch total of travel?

and 13.5 stock length plus 3 inches =16.50 collapsed length?



so whats my extended? 16.50 + 7 or 16.50+14?
You're gonna be confused until you quit playing with numbers and do what I told you to do. I couldn't even tell you how much bump stop compared to stock that I run because I don't care about that number. I set them up to where they need to be and set up my shock mounts for the shocks I use. Simple as that.

rockhard98 I've got the skyjacker 6inch long arm (rockready 2) kit on my 98. You can always call skyjacker and get the spec's, they should be able to tell you over the phone. Then just cross reference those numbers to a blisten equivalent. Personally I'd get them 2" longer in the rear.. but anyway that should get you the correct length to start with at least.

Skyjacker has good customer service info, and they will tell you anything you need to know ( on there setups anyway).

CONZILA How does this add up?
So you know 1.5" bumpstop extension with a 3" lift gain over stock gives you 1.5" additional uptravel over stock...so call it ~5.5" uptravel total.

Im working with a 6inch lift and 3 inch bumpstop

read these:
bumpstops, shock length, and tires size. help me iron out the fuzzy points.. - Page 20 - JeepForum.com

Imped Pull the springs, disconnect the sway bar and current shocks. Just deal with a freely cycling axle. Set the bump stops up correctly if they aren't now then set the foam piece aside. Full bump is the upper cup and lower mount hard against each other.

CONZILA unfortunately I'm thinking the same thing....

I went based off of Bilsteins website and I guess that is not the thing to do.

Any links you can throw at me to help find ext/col lengths?
Thanks

you need to do some homework on compressed and extended lengths, limit straps, and bumpstop extension requirements.

then you'll have the knowledge to buy the correct shock for your travel requirements, and install the proper equipment to keep those new shocks from becoming damaged.

CONZILA I was even going off of the bilstein website, ugh.
So how exactly do i figure out ext/col length that I need?
01-28-2013 11:26 AM
Imped If that's the longest 5100 they sell, then why do I have 12" travel 5100's?

Hint: Quit going by "lift height" BS numbers. Bilstein has more 5100's than you know, you just need to purchase them by ext/com numbers.

Hint #2: 5125
01-28-2013 11:21 AM
CONZILA I thought so but its the longest 5100 rear they sell
REAR collapsed length 15.4 inches
extended 25 inches
01-28-2013 10:59 AM
Imped Your shock it too short. What's the extended and compressed length?
01-28-2013 10:05 AM
CONZILA OK but I purchased and installed the longest 5100 offered its for the 4-6 inch LA kit. I installed it to the upper mount and cut the strap and at full extension it was only 1.5 inches lower the the bottom shock mount. telling me I only have 1.5 inches of down travel. What do you think
01-28-2013 09:26 AM
CarolinaBound The shock represents the max amount of travel you can get, all the other factors such as bump stopping for interference are what limit it. For up travel your going to have a bump stop so that that it doesn't bottom out, but more likely your going to have to bump stop it to prevent your fender from taking chunks out of your tire. The down travel is mostly limited by that too, since you can't have one tire droop without the other going up. So having a 14" travel Bilstein won't be different from the 14" travel Rough Country shocks you likely have now.

Who has experiance with bilstein 5100's on a 6" long arm kit? part numbers?

I'm looking for the personal experience of some who installed 5100's with their 6' la kit and how things went for them and what part number did you use? How was the performance of the shock? Did they allow full up and down travel? Thanks
