Shackle reversal quesions

What is the advantage of doing a shackle reversal for the front end. I was browsing the MORE website and saw the reversal kits.

Smoother ride, more nose dive when stopping, um...

I have it, like it. The nose dive issue is not that bad for me. Doesn't seem to hinder it offroad.

I have it. I believe I get a smoother off road drive and I also believe it tracks better. They ride better in pot holes and rocks.

There IS a downside and it's been mentioned; the Jeep will nose dive if you brake hard. If you're an aggressive driver on the road and rely on your brakes, it might not be for you. If you drive as conservatively as I do so that you don't brake hard, it's really no big deal.

I built my Scrambler with a front shackle reversal and Rubicon Express 4.5" YJ front springs. Works great - better suspension action, smoother ride, and more solid feel in the steering. I have heard the warnings about brake dive but it's not anything outrageous or unsafe and really not any different than that of my old Dodge Ramcharger. I'm actually thinking about doing the reversal on my old CJ5 too.

Granted, I don't push my jeep hard but it drives great with the reversal on road and light trails, love it, YMMV.

As I mentioned on another thread, a local 4x4 shop owner told me he will no longer do shackle reversals for liability reasons.

He made that decision after witnessing a couple of nasty crashes at MOAB, that were directly linked to the reversal. The Jeeps were going down a steep decent, they nose-dived causing the rear tires to lose traction and began hopping, then the drivers lost control. Other standard-shackled Jeeps navigated the decent without problem.

The other problem is clearance issues with the front tires, since the axle moves backwards with a reversal when the suspension is compressed.

the military had their m38a1's with reversed shackles. also their m170's as i had one of those once. rode very well and, perhaps due to the extra heavy springs in the suspensions on those there was little nose dive when braking.

Is this hard to do ?
My '83 has a 1 3/4" body lift, I replaced the shocks last spring and there was no difference when I hit a pot hole or even mild bumps. It still handled just as poorly as before.
I'm almost positive that the leaf springs are the original, if I replace them... Will it handle bumps and pot holes better ?
I don't want to spend the money and be disappointed again like when I did the shocks.

All you have to do is stand in front of your Jeep (not running!) and look at the front shackles while someone turns the steering wheel hard from side to side. Watch the shackles sway. That's what happens when you're driving. That in addition to the front dif following a more natural rearward motion when hitting bumps instead of being pulled forward INTO the bump made it a no brainer for me. I never noticed the nose dive (or even heard about it) 'til now and I've had the M.O.R.E kit installed since 2003. I have to admit though, it still didn't handle like a BMW. So I went with a Borgeson needle bearing steering shaft. Still not perfect. Then an M.O.R.E steering box brace (while your watching those shackles sway with you buddy turning the wheel, watch the steering box too... you'll be amazed). Anyway, short story endless... It's a Jeep and it can be scary on the highway! BTW mine has no lift, 11.5 x 32 x 15's, and poly body mounts. Maybe I'll try the steering stabilizer again...

I'll take a look while having someone steer it. The steering box is new, it's the H1 upgrade and at first steering was fine, now it's sloppy and binds a little. The steering stabilizer is next on the list to be replaced.

I'd like to take a look at all these reverse shackle CJs that are experiencing dangerous front end dive. I bet most are using flat, lower spring rate front springs, SOA, or both. Like I said in my post earlier, I'm using a pair of RE 4.5" YJ springs up front and SUA - I built my Jeep tall(er) to increase departure angle and *** dragging concerns with a CJ8. Dive is barely noticeable and certainly not objectionable or unsafe and I get full spring range of motion when I'm on the trail. I also have a significantly longer wheelbase on my CJ8. I haven't done any Western slickrock trail riding so can't comment in how the shackle reversal works in that type of terrain but it seems to be working well for where I ride - East Coast trails and obstacles, mud, and torn up local roads. Bottom line, suspension modifications need to be made after carefully weighing of pros and cons, intended vehicle use, and type of terrain expected.

Good discussion but it would be more helpful to the OP if someone out there that has actually run with a shackle reversal that didn't like it or has had some negative observations in its use would chime in.

I had someone turn the wheel while I watched and noticed the steering box move. When I put in the H1 box everything seemed tight, but I must not have torqued down the bracket bolts enough.
They are tight now and everything feels much better.
I'm still interested in the reversal. Anyone post up a good step by step ?
