Jeep guy needs an answer to a question:D

What is the spring rate for the stock coils on a '95 FJ80?

Thanks:D

I searched, you guys don't talk about springs all that much.

I believe the 80 Series guru is Christo Slee, I'm pretty sure that's his name:confused: Slee Off Road is his business, does alot of 80 stuff, probably has a website. ;)

Now get you ass out of our forum you frikkin Jeep guy :D :D :flipoff2:

bla bla bla, would you feel better if somebody punched you in the throat and called you a punk ass beeeeyatch:rolleyes:

way too civil for you over here, so get the fawk out:D

Just spent 15 minutes paging through the 600 page tech manual for my 80 series. I couldn't find anything about spring rate at all.

:beer: Thanks for looking.:)
Fat trucks weigh around 6000#, right:confused:

Here is the Fat Truck the springs are out of:D

GVWR for my 91 80 series is 6525 lbs.

Rocker Knocker on Prichett? What a fun trail.

Yep, he walked it:D

We were with some UROC guys, and a bunch of other SWB rigs. The Fat Truck looked out of place, but did everything...with the AC on of course:D

Edit: found it

here are some spec for Old Man Umu 80 series coils, I don't have any stock spring specs

Spring number /bar dia/ free height/number of coils/coil weight/spring rate(lbf/in DS PS)

850 17mm 495/505mm 9.8 7.3kg 220lbf/in
850j 17 515/525 9.8 7.3 220
