Got it
 
Just paid for my 8.8 rear. :dance:the first of many steps in my drivetrain upgrade. probably going with 4.56:1 gears and ARB lockers. It is going to be a fun project that i have been wanting to start. :D
here is the bracket kit planned for it TJ 8.8 Swap Kit with Truss

It has 3.73:1 LS right now which I may run for a spell as I save for the lockers which are right around 1000 each. but unsure if I want to install it before re-gear. :rolleyes:

Save yourself from having to redo everything further down the road and go with a four link. In a couple of months I will be hacking off all my Teraflex brackets and replacing it with the bracketry for the four link. Nice chunk of change down the drain...

Rock Krawler Suspension, Inc. check out the tj stuff, I have actually installed a few of their kits on tjs. doing a LJ right now. If you lack the ability or knowledge or are just plain lazy ( I tend to fall in this category) It is a easy way to go 4link

I agree fully with this statement

That TJ kit looks great. will I still need to purchase a bracket kit or does this thing have all the components i'll need? http://www.rockkrawler.com/images/RKTJ_4LINK_UPG_02.jpg
I'm guessing you just re-use the spring perches
Ok I see how it works now. how are the road manners wth this type of rear sus?

wanderlust 02-24-2012 10:15 PM

it is very complete.. you can get it in various levels of complete, best bet call them and tell them what you are trying to do.

wanderlust 02-24-2012 10:17 PM

BTW 4 link kicks butt, I already miss mine

Colo-TJ 02-24-2012 10:20 PM

defenatly got me thinking.....

Yes, but you can console yourself with dreams of your three link :rofl:

If a four link is set up correctly they are far superior to stock, especially with a lift. Check out Imped's build thread. He started with a RC four link. He talks a lot about its' good and bad points. The only real issue he had was excessive squat. That he corrected with different mounting points.

See the biggest problem with a lot of the production four link kits is they try to use existing link mount points. This, in the long run, sucks because your roll axis will be skewed and the anti squat is also going to be out of control.

This is why I am building mine from scratch. That way you can get a good roll axis (horizontal) and can set up to adjust the anti squat anywhere from 50 to 100 percent. This simply cannot be done using existing bracketry.

If your interested I'll try to post some of my planning work and where I 'm trying to go with it.

See, and you thought it was going to so easy :D:rofl:

TRS Magazine - 4-Link Suspension

Here is a link to a very good article on four link design. While the particular design doesn't suit itself to swb Jeeps, it covers all the basic concepts needed to plan and understand four link suspensions.

If you have questions, please ask, the first few times through it can be pretty confusing ;)

you are right, the RK stuff is not perfect, but can be modified easy enough. Agian, I am lazy so When doing jobs for others I start with prefabed stuff and adapt it to my standards

Well, I promise not to tell anyone else :rolleyes:

It really is an excellent starting point. Fred Williams is a very sharp guy.

Been through a lot of the four link threads on Pirate, lot of good information and perspectives on four links pertaining to rock crawling. Lot of gobblety-gook also so it's a good idea to have the basics down before you start digging through a twenty page thread :whistling:

I use the cost effective approach. If it is cheaper for me to fabricate or if I can't find exactly what I want, then I fabricate. I always have to figure in welding costs since any suspension stuff that I do is tig welded by a certified welder.

The axle truss is a case in point. I went with the Synergy truss because it was exactly what I wanted and to fabricate it would have been a major PITA. Everything else is pretty easy so I'll just make all that myself. I intend to build it with a lot of adjustment capability so I doubt that I could even find exactly what I need.

Oldguy 02-25-2012 11:50 AM

Question for you, Chad. You have a 3 1/2 Teraflex lift, right? What control arms are you using with that?

Colo-TJ 02-25-2012 06:57 PM

This is what it looks like now under there. sprry about the mud ..havent had a chance to wash it out from last weekend yet

Hey don't sweat it, you should see the mess under mine :rolleyes: If I didn't know what links I have I couldn't identify them on a prayer :D Look like big mud covered hotdogs...

Ok, so your lowers are stock. Assume your uppers are also. Thought you might have installed the Teraflex long arm when you did your lift. No matter, probably better to start clean.

Lets wait and see what Wanderlust has to suggest about the RC kit. Would probably work fine if you got rid of the squat.

wanderlust 02-26-2012 11:20 AM

The RK kits are easy to get the squat out of. The biggest problem with most current TJ setups is the axle loading and unloading "hop" they get. I took a new friend out yesterday to RAM to shake down his setup and see where we needed to go with it. He has a rubicon express 5.5 longarm, procomp adjustable piggyback shocks and has been bastardized by a ton of different people over the years. He is running a 37inch radial IROK tire. Friday night I gave it a good inspection and centered his axles. Had to actually cut his trackbar threads to get more adjustment just to get the damn front axle to center, was a total mess. we set his wheelbase at 94.5 inches, squared everything up and decided to go with it.

So, the story, his jeep is great on ledges and seems to now drive on the street better. We are going to lower it by an inch, go to a 4link rear and ditch the rubicon express radius arms..

The problem is the thing just hops like a pissed off monkey if it gets in any type of traction loss. We where messing around on a few 3 ledge waterfall type climbs at the park. I would rate one of them an 8 and one a solid 6. there was a buggy that got denied on the 8. It took a little work but I made it up, THE only reason I did is I get ZERO hop out of my setup and can let my tires spin and find the traction they need. Dude with the buggy was very confused, but realized his setup was wrong and he would get axle hop something fierce.

Moral to all this is a well thought out setup is splitting hairs and taking your time. I will update on the TJ after I get my dirty little hands on it again. My friend is all in so I am unsure of what I am going to do with it. I like his crossmember and will build off of that for the 4link rear. I may go with the synergy truss on this jeep. From a blank canvas I choose the RK stuff hands down, only because I have spend a ton of time with it.

p.s. I am no longer on a four link rear, I am back to a factoryish rear setup unitl I get my 3link stuff sorted out.

Congrats on the upgrade bud. You'll love the 8.8 with an ARB in it. That's what I have, and I love the lockers. My lockers were 850 apiece this time last year. Sucks that the price went up that much in only a year. :(

Chad, watch 4WheelParts for one of their big sales. You can usually get about 20 percent off, and I'd guess the ARB stuff would apply. They a big labor day sale 3 or 4 years ago and I got my Detroit Trutracs for like 25 percent off. On high buck items it can save a major chunk of change.

Ohhh kayyy, 35's, long wheel base, close to stock rear suspension. Even with a very high driver quotient, isn't that kinda pushing it? :rofl:

yeah thats my luck... i always decide to do these things just a little too late. oh well Like you say Ed i am sure i'll catch them on sale if i'm patient. problem is I want it and I want it now...LOL
it's all good. the 8.8 that i bought has the factory locker so I can run it untill I get my lockers and re-gear figured out :D
