Yet Another LCog TJ Build

Here is my build thread.

Mission Statement-
To provide a fun somewhat liveable daily driver that can do moderate wheeling. The general purpose is a road going tow and fun vehicle as I ride dirtbikes as my primary fun activity. Must be driveable for wifey as I leave it at home and take her car for long commutes. (This has changed some since I wrote it lol)

The Jeep as I got her-
1997 TJ with 54,XXX miles on it
-Auto 32RH, which I pretty much had to have
-There is a throttle body spacer on it (have to check brand)
-Factory 3.07's D35/D30
-Old Man Emu Lift with 2k miles on it. Properly done with track bar mount moved and beefed up. Steering stabilizer as well
-JKS front sway endlinks with disconnects
-JKS 1.25" Body Lift
-JKS 1" MML
-32 x 11.5 KM2' and wheels with 2k miles on them
-Clean frame and underpinnings (hard as hell to find in the rust belt)
-Clean interior
-Hardtop in perfect shape
-Good soft top
-Bikini Top
-Stereo upgrades (5.25" conversion up front, sony deck, new sound bar speakers)
-Rear bumper I think smittybuilt

What I have added so far-
-Winch and synth line
-Rocker guards
-Fender flares
-Fog Lights
-Front Hooks
-Skid Row Engine Skid
-First Aid, recovery strap, tree strap, and Fire Extinguisher
-Dog mods http://www.jeepforum.com/forum/f9/tj...roject-1205895

Coming up soon-
-Monstaliner inside

I have sourced a local HP D30 and a 8.8 rear. I will be going to 4.56's. That part is set except I need to either tackle the re-gearing myself or pay someone to help me. Yea.


So here is my current dilemma, which is essentially long arm versus short arm-

Items I'll need for LA-
-Tom Woods SYE kit
-Exhaust pieces
-RK Long Arm Kit
-ruff stuff D30 diff cover
-Skid Row LA engine skid
-Someone to help me weld it in/install it

Items I'll need for SA-
-Tom Woods SYE kit
-8.8 Brackets
-Control Arms (RK or Savvy)
-ruff stuff D30 diff cover
-Savvy UA or UCF TC skid (Long Term won't need to be done now)


Essentially the costs end up the same once you factor in the Savvy Complete UA. However the UA and the SYE could be held off on, which makes SA a bunch cheaper, but only in the short term as I look at the Tummy tuck/SYE as a must do for short arm. UCF makes it about $600 cheaper overall as it's that much less than Savvy UA.

Since that last post I have now started leaning towards this-

-RK Rear Short Arm triangulation kit
-Tom Woods SYE kit
-8.8 Brackets for lower rears
-Front upper and all lower Control Arms (Savvy)
-Savvy UA (Long Term won't need to be done now)
-Savvy Track Bar Kit

I feel like this would maximize ground/belly clearance (once I can afford the UA) and provide a bunch of flex with a good road ride. Since I don't plan on changing my springs/shocks for some time this setup should work well with the OME stuff.

Uh, 32"s and and an OME(about 2" I assume) lift, doesn't exactally qualify as a LCOG rig, just saying'.

Keep the 2 inch lift and run 40s. That's LCOG

Eventual plan is 35's, left that out of original post.

32's are just too new to get rid of them.

I'll recommend against the RK 4 link. While it does its job fine. the geometry while using stock frame and axle brackets is much, much less than desirable. Very high antisquat numbers cause major hopping when climbing--no good. The dog leg arms are also a pain in the ***. I ran it for a long time and am very familiar with everything involved. I recently swapped out the RK arms, stock frame mounts (upper and lower) and axle LCA mounts with custom arms and Poly Performance frame/axle brackets. I kept the RK truss. Everything is much, much better--perfect antisquat, no hopping, adjustability, the straight arms are easy to live with, much better clearance everywhere and no more axle wrap due to worn bushings. You can spend a little more money and do something like that instead of the RK. I don't think there's a better setup out there that utilizes short arms.

Don't forget about outboarding/extending the shock mounts and moving the spring perches. High pinion angle + stock spring perches and shock mounts = don't work.

Do you have a build thread? I am clicking around on the PP website to try and get an idea of cost to make a custom 4 link rear... where did you get the custom arms made?

Made the arms. If you can weld, you can do it all.

So after spending some time clicking around and reading a few other build threads I think I am gonna aim for a custom triangulated rear with short arms (aka copy Imped). I never intend on going higher that the OME lift so it seems silly to do a long arm. It also allows me to stage my build better.

I can get my axles sorted out 100%, then gather parts for the 4 link, install my HP D30, then do the rear link/SYE/rear axle all at once... just need to see how I can get it done as I don't have the garage (air/welding) to do it. After that I can save up and purchase a Savvy UA and upgrade my front control arms and mounts.

Standard OME Shocks
Front N66 23 extended 14 compressed
Rear N67 22 extended 13.5 compressed

So my shocks will end up as my restrictive element in terms of rear travel?
