here are some pictures

[Brandon95yj]

and some more

[Brandon95yj]

[Brandon95yj]

and finally!


List of this still to do.

Set up the gears

Weld new yoke on driveshaft

It is hard to tell from the pics. what link ends did you use.

[Brandon95yj]

Ballistic forged 2.63"

Lowers are 1.25" shank

uppers are .75" shank

[cctbj]

looks good

Dan,

If your interested call and talk to Stan.

He gave me a good deal:flipoff2:

I still have a few months before I can do the links. :doh: I'll have Rippey talked into it by then, so we'll do a group buy on all the parts. :D

:thumbsup:

[Brandon95yj]

good luck on the group buy

:dan2: +:alan: (rippey not alan) buying parts together :lol::cheers::flipoff2:


Anyway...

One more update.

Last night I setup the gears, installed the axle shafts and built/installed the driveshaft.

Tonight I will be bolting up the diff cover, fill fluids and welding two tabs on for my limiting strap.



Again I need to say a huge thanks to MDMike for letting me use his garage and lift for two weeks:flipoff2:


Again thanks to Appalachian Offroad for letting me use the shop last night to set up the gears and build the driveshaft.

You guys are the best:cheers::beer:

[Brandon95yj]

drive it today


wow this thing rides so nice.


roll is very minimal and it doesn't squat or lift

the link calculator seems to work well:beer:

[frosty]

Bring this back up. How long are your uppers and lowers? Double triangulated? How much separation between the uppers and lowers on the frame side and then the axle side? Lowers on the center line or so of the axle?

I am thinking of changing my frame mounts around and moving them above the frame rails or in line with them instead of building some skids up to those rock magnets I call frame mounts. :lol:

I saw yours in Dan's thread. What size heims on the lowers and uppers? Want to answer the numbers I asked Brandon about? And lastly do I see some stock frame in there?

[Brandon95yj]

Pulled from my link calculator

Links

Lowers are 40.5"
Uppers are 36"

Double triangulated

Anti-Squat 95%

Frost PM me your email and I can send you the snap shot of my link setup in the link calcuator

Pink Arrow is Approx location of the upper frame mount
Yellow Arrow is the driveshaft
Red Arrow is the lower link mount. My crossmember is 2x2 box that is under the frame rails

[Z28YJ]

Uppers--38"
Lowers--33.5"

Separation @ Frame--6"
Separation @ Axle--9"

The lower link mounts on the axle are pretty close to the centerline.

The lower heims are 1.25, 1".
The upper heims are 7/8, 3/4" (I think).

You can see the frame pretty well here.

Thanks guys.

Took some measurements tonight. They might be off by .25" or so either way but they should be pretty damn close. The only one I didnt try to measure was the center of gravity height.

I think I might just leave things as they are and build some ramps for the frame mounts. I think the numbers look good for what its worth. Clayton rear kit that I tweaked and put where I wanted.

Need to plug in some travel numbers so this is just static numbers.

the numbers look pretty good. Ideally the roll axis should be a little higher (general rule is that the number should be between 75% and 125% of your wheelbase)

[67temp]

Which version of the calculator are ya'll using? Also how do you figure the COG height?

[frosty]

I used whatever the latest one is, 3.1d I think. I didnt do anything yet with COG but a guess. I'll probably measure the top tranny bell housing bolt. Not an accurate measure but should land me close enough for horse shoes and hand grenades.

[67temp]

Looks like I need to update mine. I have 3.0 and it doesn't have some of the travel info.

Is the cog the top of the bellhousing? Seems like that might be kinda high. Looking at my numbers almost half of my vehicles weight is unsprung. I couldn't imagine having that much weight above the top of the bell housing. I've also heard some people measure to the centerline of the crank.

[frosty]

I thought that was a measurement I had read for a SWB Jeep but I could be wrong. There is a way to go about measuring it to get an exact number but I am not worried about it being exact. I was just curious where I ended up in the calculator.
