Though have bee looking at some other designs and ideas

Found this interesting a F150 radious arm....?

imagine the weight on that last one! ahha

i got a price back from sky on their bolt on kit... its around $200 to ship the $250 kit =) hehe and worse still with my setup the kit would require modification and is shipped unpainted for that reason.... so factor in "modification" to make it fit and its a pretty costly exercise.

any other thoughts?

worked out to cost a heap by the end of it.... i dont want to talk about it... lol

basically i needed perches below the diff again and plates made to hold a square u-bolt (custom made ubolt mind you), then as the kit is made primarily for fords and holdens my kit is custom machined.

All up i estimate around the $1k mark =(

on the up side - itll NEVER bind up and it works - making the title of this thread now incorrect =)

I must have missed this photo, keep a very close eye on your shackle mount as it WILL fatigue and pull away if your car gets much action.

Not meaning to offend you but looking the underside of your car, it doesnt look like it gets much of a thrashing so you may be OK.

Update...... You were right :oops: the X member had bent upward, Its a bare chassis again now so I have just finished strenghtening it.

Trac bars have now had 3 good test runs - lots of on-road, some mud/rock last week and some sand today... they've 100% solved all my rear wrap and tramp i was getting - not a single driveshaft vibe since fitment =)

Best part is they simply cant bind up! see pic 1 (barely flexing), pic 2 and 3 are under the zuk in that position.

Ill be trimming off that lower mount hole on the shackle plate too - i haven't bashed it on anything yet - but im sure if i dont trim it back i will.

is it strong enough to hang that below the axle? will it break with a hard enough hit straight on say a rock?

linc - yep - an expensive exercise indeed - but it works PERFECTLY - and you cant deny the R&D that goes into it, and the machining costs of all the parts (keep in mind the bushes etc are all machined to my specs).

strength wise - its made to take vehicles putting out over 1000hp... and if it does cop a huge hit, it will break at the heim joint's threads into the bar - so all thats needed to fix it is a heim joint replacement - not like a lot of bars on here that tear mountings off when they fail =)

that much money for some thing that is a bolt on. sorry but i think you got ripped, cost me $320 to have this set up on a old kingswood van a few years ago. they work great, let me go a softer spring set up to get more weight transfer over the back wheels off the line with out breaking uni's from axle warp

dont get me wrong - i know it was expensive - but there was no one else who could do it for me and had the experience in setting up this kind of trac bar... unfortunately i had to bite the bullet and fork out. but you have to admit - its a tidy and top quality job, and i know theres no way i could have built it myself for under $500 as it is, and given the lack of experience i'd likely have spent more money rectifying or re-doing parts that i got wrong (trial and error). in the end, yes its a bolt-on solution and yes its expensive (dare you to see how much it costs to get caltracs made for a zuk!) - but it works and it works well, and given my limited space above the axle it was the best solution - biggest of all is you are all forgetting how much it costs to have things custom made to suit your individual needs... there is no off the shelf suzuki sierra caltracs/oztraks system, so someone has to make the first one =)

Been following the thread with some interest... been good stuff so far. But the geometry certainly taxes the head a bit, and design "oversights" lead to nasty diff damage.

The thing that concerns me most is the actual axle tramp, whilst the diff angle change obviously isn't desirable it doesn't appear to be the most serious problem in terms of causing mechanical damage.

What I'm wondering is whether a horizontal "shock" mounted from the diff - back to the chassis could be made to damp out the axle tramp ?

it seems to me that theres' a significant difference between the fundamental frequency of the axles normal travel and that caused by tramp. and therefore the damper would have little or no effect on normal suspension movement but might be made to damp out the axle tramp .

The "advantage" if this could be made to work is of course that its pretty independant of suspension geometry etc etc - if you can see what I'm getting at.

Sort of like a steering damper

Anyone - any experience / ideas ?

It seemed like a much better idea when I started it than it does now.

I'm just running out of the office MM, but your idea is sound. These were available (and common) in the US in the 80's - they were known as "kicker shocks" and very recent F150 fords used them too.

I've played with the idea of using one of my old Gwagen Bilsteins in this application - they are super stiff.

There's a number of references on the net re Kicker Shocks.... also a Bilstein listing for one to suit a Mustang - and I have healthy respect for Bilstein.

Given the significant mass and torque of the Mustang they could well be a candidate for a 4WD.

Rancho also appear to do them - hmmm..... interesting

Also another shock based system has a coil over and runs from the top of the U bolts to the forward spring eye. Not really practical for my application but another example showing the principle.

Overall might not be perfect but seems potentially much more forgiving of the complex geometry changes seen with leaf springs - well worth following up IMO.

Well it has been 10 month or so, and so far no problems at all, not one :armsup: the springs that were new when I started this experiment still look the same, it launches like a demon, doesn't make any noise and apart from the odd squirt of grease has not required any attention at all.

I know a few of you are after pics, but I am waiting for advice from my patent lawyer :lol: (OK OK I am slack)

Steve, I would be interested in your opinion on this setup, apart from the hideous clearance issues what is your take on the geometry.
