    I've been playing around with some anti-roll bar links, to make some "quick" disconnects. This is what I've come up with:

    uploadfromtaptalk1399897922223.jpguploadfromtaptalk1399897956506.jpg

    The original rod is 8mm dia. I cut that in half and welded over some 12mm x 2mm tube. They were a tight fit anyway. The 16mm x 2mm tube slides over the 12mm tube. I've drilled 6mm holes through to accept the pins. I've extended their length by 50mm.

    I do have some concerns however. Firstly, when coated in mud, I reckon it'll be a real fiddly job to get the pins back in. Secondly, are they strong enough?

    And last but not least, when removed, how are you supposed to prevent the anti-roll bar from dropping? Is it ok to just remove one side?

    I've heard of alternates where the actual sway bar is cut in the centre and bolted flanges are welded to each half - to allow removal of the bolts. Reckon that'd be a better system.

    All suggestions appreciated.

    This is what I'd based my design on.

    Currently modifying a set of them myself. Well they are modified but they haven't gone in yet. Edit: Sorry should have checked the link. Mine are modified "JKS 3100 OE Replacement Front Swaybar Quicker Disconnect System for Jeep WJ".

    My concerns with your design would be the rod failing in tension where you have reduced the section dramatically to put the pins through. The pins would unlikely to fail in shear I feel.

    What dimensions are your pins? Edit 2: You said they are 6mm.

    I'm not overly familiar with the forces sway bars experience but looking at the diameter of the sway bar I'd imagine they are quite high when flexing off road and don't remove the pins.

    This is probably worth a separate topic on its own yes? Just a thought, not a demand :-)

    Hi Pete - thanks for the thoughts - similar to my own. The pins are 6mm diameter and I would have judged their shear strength to be greater than the tension strength of the original 8mm rods.

    Because I've drilled a hole at 6mm diameter through the oiriginal rods, their wall thickness has been reduced to 2 x 1mm. Not enough - hence why I've added the 12 x 2mm tube over the top. The added tube has been welded at the end, as well as through two holes close to the rod end.

    I suppose I could work out the surface area of steel that remains, compared to the original. In fact I will.

    Yep - probably worthy of a dedicated thread. I'll set one up soon.

    Just touching base now, it's been 8months and a few thousand KM's since I installed the lift now... How time flies! Do I have any regrets, issues or anything that I'd change?

    Hell no! It rides as it should (and the terrafirma shocks are great when the roads get rough)! I knocked off both rear bump stop extensions in one mud run a few weeks ago, purely because I haven't permanently fixed them yet. That will be rectified next weekend anyway.

    Do you know the biggest single thing that's pleased me about the lift?

    Other makes are worried! I have met a lot of new people over the last 6 months out camping, they drive all kinds of 4wds. A lot have people have commented on how well the suspension flexes and keeps wheels on the ground compared to theirs. Some of these have been Patrol and Cruiser drivers. I'm really happy with that!

    And I traverse a wombat gully quite a bit on trips to my favourite spot, kept tyres on the ground when a Defender with 3" lift and dislocation cones was dislocating springs. Another Landy (Disco 1 this time) with 3" and no dislocation cones is lifting wheels through this spot.

    Who said airbags don't flex ;-)

    Cheers

    HI guys, just wondering how those who have fitted adjustable panhards are going, do you notice any better ride/articulation ?

    I have fitted quick disconnects but always seem to forget to take advantage of them, will try out next trip out to wombat to see how much difference in front flex!

    I used my disconnects last weekend and the front seems to flex easier when driving through ruts and uneven ground. And surprisingly easy to put back in even on not so flat ground with the jks ones I modified.

    But I hope to do another same spot comparison, as I don't think my previous posts were the best examples.

    Martin, I have a weekend away camping/4wd'ing next weekend. Will let you know if there's any noticeable difference.

    A few months on now and no more rubbing on the chassis (which has to be a good thing). One that I seem to be noticing is that there is even less of the tram line effect, even with the 18" wheel and tyre combo on the road. Having everything aligned in the drivetrain must reduce stress on the Uni joints too.

    Not that I'm counting, but I just noticed this thread has had more views in 2 months than the original forum sticky posted in 2009!

    Be proud guys - there are plenty of people who have/will benefit from this thread over the years!

    Great achievement!
