missing link or drop shackles

Post by zook7177 »

trying to decide on these, i was going to go just 4 drop shackles but then i was told about the missing link system. I really dont know a lot about it but may be better than the drop shackles. What do we think????

What suspension set up do you currently have? To run m/l you will need rear springs up front and longer rears. Drop shackles should work with your current springs. You will need custom shock mounts to gain full use of both types. Have a bit of a look around on this forum its been discussed before in more depth.

Do a search. They're not very popular for a number of reasons.

Drop shackles do not improve your suspension in any way(because they have nothing to do with "suspension" they're only a hinge), they only permit the axles to move further. These were all the rage about 7 or 8 years ago, most people would now say that the added movement doesn't add capability to the car. It looks great posing on a ramp though.

In any case, fitting drop shackles is far from a bolt on - as NIK said, it requires longer shocks to gain any travel, so fabrication is involved there, along with longer brake lines and care with driveshaft angles, especially on the rear. Generally, the sellers of drop shackles don't take any responsibility for this stuff, or the fact that the added droop actually makes the compressed wheel travel up further into the guard, reducing the effective tyre size you can run.

I do not, under any circumstances, support the use of drop shackles on the front end- the effect on steering and handling is too hard to predict.

In general, they can be made to work, but there is a lot of work involved - fabrication and problem solving. Generally, if t hat much work was put into conventional suspension, it would actually work better than drop shackles.

i made some myself (pattern still on suzukiinfo website)... they really didnt help alot offroad or onroad - i got about an extra 20mm of articulation from them, but cos of the hinged nature of the shackle, whenever it got traction the shackle would close and it'd lose traction again... definitely need to revise shocks etc.

for what its worth you're better spending it on fuel to do more driving =P

I've had front and rear superior shackles for about a year and i cant fault them . With 2 in body and 2in standard legenth leafe packs i get about 1 in more articulation than a gq patrol with the same lift configuration and no sway bars but as mentioned u do need to replace standard front shock mounts with shock hoops

Don't want to harp... but a GQ with 2" spring lift will still be generating good, balanced wheel loading at full travel, where a car with drop shackles just won't. With one wheel up, there won't be much in it, but on a big compound angle they DO start to unload and the car becomes more difficult to trust.

In some situations they might work, and in others they definitely don't.

No, I have not, and you can read into that waht you will, but I have been in the suzuki club here in vic since 1993 and had seen lots of people try lots of things. From what I have seen of them on cars in the club I wouldn't spend my money on them.

I have built a few 3/4 elliptic rear cars and these don't suffer from as many quirks as drop shackles, but they're not perfect either and aren't any more necessary than drop shackles.

The best result I have seen with them was on a car running them on a the rear with a Gemini diesel and very long front springs. This car was very nose heavy and they seemed pretty good... but it was a very unusual set up. It crawled pretty much everything and never looked like it was going to pick up a front wheel- so it didn't start the car down the path that causes drop shackles to play up.

No offence taken, I'm just expressing my opinion, you're more than entitled to yours.

I had a zook that has drop on the rear and it worked very well, never unloaded on angles and was predictable. It was in the car engineered when I bought it.

Mind you it would almost be cheaper and less trial and error to just get overkill to coil the arse that a well set up drop shackle system.

yes they work but its far from bolt on and the ride quality is never there because you need alot stiffer shocks to help control them.

i made a set of sizzor shakles up and they drop down like the climex ones i made my own for $20 a pair,its a good way to do it coz if they dont work its only $20 not $600 a pair

mine work really good and improve the flex alot more than i thought they would have,give it a go its only $20 and most of that is on high tensile bolts and nilon nuts

watched them sit and "chatter" to many times. The only thing keeping them closed is the weight of the vehicle sitting on them in high torque situations.
The issues as I see them are the eye of the sring can now move basically vertically no longer in an arc like a conventional shackle this puts some additional weight in the wheel as it try to force the chassis mount "up", with a drop shackle this does not happen. Like when you use a screwdriver to wedge two things apart, as the gap grow between the points you need to exert force to keep going. Now do the same thing with a hinged bar .. and you will simply bend at the hinge.. the two points do not have to move at all.
