There seems to be a lot of pros and cons with a shackle reversal.
For those of you that have done it and run it for a while whats your opinion ?
Was it worth it ?
I see only one benifit...no shackle up front allows you to slide the spring up a rock, no shackle to invert and bend a spring on approach. Bigger tires and reversed springs seem to eliminate that problem, so why go thru all the trouble?

I've run it for a few months now with the full widths. I love the clearance up front. Mine rides way better too, but I gotta give credit to some other items that were changed at the same time, Shocks, 1 less leaf in the pack and a much better shackle angle.

Flex is about the same, maybe a little bit more. But it's hard to tell exactly because so many things have changed.

I think it is worth the trouble for the reasons you list.

I have never seen a bent front spring with a Shackle Reversal.

My approach angle is superior to those without a SR.

(this is for a flush mount SR, not the "kits" sold with the towers)

(that's "two thumbs up" BTW....lol)

Yes, I like mine and would not change it back...no bent springs, no reversed shackles, better approach angles, etc...

I love mine, had it that way since 98.
BTW I was talking to Drunk Monkey and he switched his back to the shackle in front, but he's a Drunk Monkey?????????

For a DD... better highway manner. Not sure if just me, but seems to track better.

I have used shackle reversals for almost 10 years now and would never go back. At first, I used an LCAH kit that was invented by my friend Ross Stewart. I was skeptical that it would improve the driving characteristics, so when I first put it on, I changed nothing else. The driving characteristics were clearly improved -- it tracked much better. I know others doubt this, but that is my experience.

i've always loved them...wish i had it on the 60...even with low mileage, upkept maintenance, and p/s, it still wanders all over the road.

This is a pretty classic symptom of insufficient caster angle. Bigger tires can use a little more than the stock +1 degree, especially since you have PS.

I love Shackle Reversals..... :D

I think we have pumped out a few dozen in the past few years... not a single complaint... and one of my top five mods to my truck... :D

Following this conversation it's clear to me that I should do SR on my 1981 BJ44. I just cannot decide for sure if I should do it.

I've done SPOA, it's got 35"MTs, x-over steering with Hy-Steer steering arms - power steering box (out of FJ80) is not bolted to a frame yet.

Mechnically speaking it's pretty much simple and staring forward for me but my conserns are:
1. I didn't have my front knuckles turned - is that an absolute procedure that has to be done? My spring perches are not welded in after SPOA - I can still move them. I am trying to keep stock front pinion angle.
2. If I do SR - would my front drive line anlge be critical? I got stock almost flat springs at the moment. If there will be more flex - I'd have to get some custom drivelines?
3. because of SR - would my front axle move up front? if so then I'd have to do SR first and then work on power steering box placement. Right?

Thanks,
Andrey:confused: :(

I did a SR on my fj45, but before I did I rebuilt all the steering parts(tie rod ends, front end, ect ect) and a new OME suspension, about like it came from the factory when new. I then ran 33x9.5's WITHOUT a SR and it drove/tracked wonderfull.

Then a few weeks latter I went to 35x12.5 MTR's and it was all over the damn road...just plain spooky on the highway. So I did a SR, hit the road again and it drove/tracked wonderfull again....75mph and only on finger on the wheels, no worries at all.

Also my 82fj40, with 33x9.5 drive GREAT with the stock shackle setup but if I went to a 33x12.5 I bet I would be doing a shackle reversal.

So I think that if you stick to a skinny tire(like stock width, say 9.5) with the normal shackle set up then it will drive great. But when you go to a wider(12.5ish) tire then it a SR is a good idea.

If a 40/55 has power steering it "might" make the wander/tracking less of an issue...I dunno.

On a fj60/2 the steering setup is different then a 40/55 so I don't think there is a need to go SR for handling reasons.

Hi Andrey, finally arrived here as well ! :eek:)
Did you manage to get the BMW working eventually ?

As for your question, may I suggest to seach in this sections archive... I remember reading interesting info about this stuff not too far ago...

Anyway, my guess about #1&2 is : it would be best to -cut n turn the knuckles -rotate the pinion up pointing to the tcase -get a long slipyoke (possibly cv) driveline...

did you figure out the tube work yet ?


oh and :flipoff2: welcome :flipoff2:

Bye,
