I was looking at the ECGS offerings and it reminds me of when you build a PC on the Dell or HP site. Too many options.

What are recommended essentials when selecting the options and what are some options you would not pay extra for?

Thanks!

Does anyone here have an 8.8 with an artec truss, and a long arm setup in a TJ???? The rubicon express guy said he didn't think it would work, I'm about to call both manufacturers to find out.

It all depends on what u want to do with your build. Matching gears is the most important. If u don't plan on putting your own locker in get the limited slip. If your putting in a lunch box type locker make sure you get a open carrier.

You may want to check out Clayton, last time i stopped by there warehouse in CT they were working on manufacturing one. I know they make a universal truss for a 4-link rear. They may be selling one for the long arm setup

Looking at a complete 8.8 kit and truss for my TJ. Would you need to buy wheel spacers for the 8.8 axle since is a bit narrower?

I suggest centering your pumpkin to your driveshaft then use a wheel spacer on the short side

Depends on your wheels back spacing and tire width. Probably not.

Artec says that it will work, guy pulled up both products I was looking at online and said he sees no problem. Especially since the artec truss and swap kit for the 8.8 is designed to un-bolt the 35, and bolt the 8.8 in. I don't know what to think now. I NEED to get the jeep up and running with rear wheel drive soon or I'm gonna have problems. Been running front wheel drive for a month or so now.

there's a short side?! How much shorter we talking? I know it's only 60" or so.

It is only offset 2.5 inches more. Nothing to worry about. Yes there is a slightly shorter side.

You want your drive shaft going straight back to your pinion. Otherwise you will get driveline vibrations and added stress on your u-joints. You only want your drive shaft to have one angle. A compound angle will only cause undo stress

Is that so? Compound angle huh? The d35 is offset as well, should we recenter it? How about the front pumpkin ? The two inches the 8.8 is shifted over isn't enough to hurt a thing. I run the 8.8 with a custom flush tummy tuck and 3 inches of suspension with zero driveline issues. The driveshafts are designed to deal with mild angles.

I do it the same way everyone else does. All you're doing is wasting money. It's going to be annoying to set your brackets up off center and there isn't enough room on the tubes to fully center the pumpkin anyways while still retaining stock geometry because of how close the lower arm brackets are to the end of the tubes.

So what's recommended? Center the axle or center the pumpkin?

Just throwin it out there. It's barely off center enough to notice. And I may be wrong but the tcase rear output it likely not directly centered on the jeep anyways. It's actually slightly to the pass side as I remember.

Even if the diff slightly off center, by very design, the tcase and rear diff will have equal angles at the output and input, when viewed from above or below (below being easier to view it from obviously) and being that it's only at a slight angle as goldensahara mentioned, it's well within the operating limits of the u-joints.

U joints will cause vibrations when the operating angles are unequal by more than a few degrees.. as they are trying to move through different rotational arcs. There is plenty of literature on the interbutts that will explain what im referring to. But in no way is having the diff offset on an 8.8 going to effect u-joints by adding any additional stress as has been suggested.

I would be more concerned about ensuring a proper pinion angle for your application than a sligh diff offset. Even on the ford explorers the tcase isnt inline with the diff and they have no inherent issues.

Thanks for adding that prox... I just assume if people are swapping an axle they understand the basics. Now you've spelled it out, no excuses.

No problem. I would hope people would understand that too.. but now hopefully they do

Now if anyone wants my real opinion... I say go with a ford 9" instead lol

How is having your diff offset any different then having the wrong pinion angle? With the double guardian u want it straight back to the pinion. Period

Because you are changing the angle at the tcase output yoke equally to the input yoke on the differential when the diff is offset to one side or the other.. that is mathematically irrefutable. The sum of the angles at each yoke must add up to 180°, and the sum of all 4 angles have to be 360°. For example with an offset diff you have an angle at the tcase when viewed from above of 145° and 35° then the angles at the diff (also when viewed from above) have to be 35° and 145°.

145+35=180 and 180+180=360

With pinion angle, which is a measurement best viewed from the side, you are not changing the angle of the tcase output when changing the pinion angle. To do that you would in effect have to rotate the tcase output downward as you roll the pinion upward, which would mean you would need to mount the engine higher to match.

You don't have to use a double cardan shaft either, with a fixed non cv yoke on the tcase you can use a shaft with built in slip and only 2 u joints, making sure that: 1, your tcase output angle and pinion inout angle are equal, and 2, you are not operating beyond the angles the ujoint is designed for.

The 8.8 axle in my tj is centered. Diff is on passenger side by 2 or 2.5 inches whichever it is. Pinion angle is 1° lower of drive shaft centerline. Have had this setup for a while now and its as smooth as glass. On a 4" lift with short arms, tummy tuck, sye and double cardan drive shaft.

9" would be nice but staying stock width for cheap the 8.8 takes the cake.

9" rear and front or a 60 for the win.... But now we are talking money I don't have

(Meanwhile I'm looking for a narrowed 60 go figure)

Does the 8.8 have C-clips? Also if I get this axle rebuilt I won't hurt anything by welding the mounts on later will I? And welding the tubes.

Yes. No you shouldn't. At most the seals. Why not do the brackets first?

You'll be fine just weld a little slower. I mean anyone swapping in a used axle does it. Most guys do replace seals. I left mine in because they were good and no harm.
