04 LJK Repair, Redo, Recycle - The 3 R's of a First Build

[MattTJRubicon82]

we got 12" King Coilovers in on my stretch and did not rub. For us when frenching into frame we went all the way to inside wall of frame, no bit of top or bottom of frame remaining then set Barnes Coilover tower in there. I do run 1.25" wheel spacers as well, but we would not contact the coilover/spring during flex.

To be fair, I cant find more pics these were during mockup and prior to trimming checking for clearance.

What is your effective backspacing front and rear?

What is your effective backspacing front and rear?

Just for my education (and anyone else wondering), is "effective backspacing" the distance from the plane of where the stock hub face would be (if it had stock axles) to the plane of the inside edge of the rim? Considered to account for wider axles and wheel spacers in order to compare apples-to-apples?

 

[MattTJRubicon82]

I Run KMC Grenades which are 3.5” BS if I recall and with 1.25” Wheel spacers. Found a couple more pics we’d be close without the spacers but it would/should clear.

lol not gonna lie I wouldn’t be able to answer with 100% certainty either.

Effective backspacing would be the backspacing of the wheel, plus any adapter/spacer that you use. For instance, I have a JK pintler on my Jeep. That wheel is about a 5.25" backspacing. With my 1.25" adapters, my "effective" backspacing is ~4"

The post above, with a 3.5" backspaced wheel and a 1.25" spacer, his effective backspacing is 2.25" which is kinda ludicrous.

Thanks for the explanation, was my general assumption on what it meant, minus the ludicrous part. Thank you for clarifying.

Front and rear?

What Mike said.

 

[MattTJRubicon82]

Front and rear?

yeah

 

[mrblaine]

yeah

In that case, it is not missing the ludicrous part. Or at least that is far less backspacing than is desirable. You can actually have some fun with it if (a) you want to learn something neato and (b) have good brakes and or a selectable front locker with (c) mostly stock steering.

Provided you fulfill the above requirements, get on a high traction surface like asphalt and lock it up. Get on the brakes hard and then try to turn lock to lock. Gets very interesting when the tire has to skid to turn. Even more interesting when you note that one side has the tire rolling forward and the other has the tire rolling backward. The skid starts there on a locked axle when all the slack gets taken up in all the splines and the tires lock the steering up.

If you have enough steering, you can get it to skid the tires and turn all or most of the way.

Not to derail the subject but @MattTJRubicon82 You have some bigger kahuna's than I, cycling the jeep with coils and a couple of tacks holding those towers in place.

It was perfectly safe bc the operator was forklift certified. lol

Mine was our first big dive into TJ stretches definitely lessons learned and improvements along the way thru buddies own build and one they are on now.

Below is buddies jeep, similar setup race line 3.75” BS with 1.25” spacers.

Tj axles?

 

[MattTJRubicon82]

Tj axles?

Yes mine are factory TJ rubicon 44's chromos, etc; Buddies are ECGS crate TJ Dana 44's , and current stretch is built 44's.

 

[mrblaine]

It’s amazing how everything has to be in like one spot to make it work. I think Blaine has once managed to fit 12” CO in stock width, which I cannot comprehend.

The rest of it has to be there. 35's, 4" back spaced wheels, 12" Fox 2.0, 6" uptravel in the front, 6.5" for the rear, stock width Rubicon axles, no wheel spacers. I lack the skills to do that without going all the way through the frame and into the reinforcement by about an inch.

I did 14" 2.0's on 64" wide axles with 37's. Same and another one I'd rather not do again.

Well I thought the e-brake cable would be easy but it’s not. There’s not much room to put it still. I cut a piece of tube and snuck it in as close as I could. It seems to pull okay by hand. It’s a bit farther forward than I wanted it but dang spring is in the way.

 

[B00mb00m]

Something got out of whack somewhere, my driver bracket ended up higher than my passenger bracket. I need to recheck axle position tomorrow. As it sits everything clears tho which is good.

 

[sierradmax]

Definitely fix that bracket. It's not parallel to the axle!

 

[B00mb00m]

It’s not parallel on purpose actually lol, that’s because in the stroke of travel the inside corner will make contact to spring cup, so I angled it a little to make the clearance better.
