Not wanting to be a partypooper but -
The main point of the lower arms is to keep the rear axle steady against pull so the top arm must need to be done the same or its 2 x modded arms v one stock arm ?

I'm saving up for top arm joints Mr G. _________________

I bet yours are better quality as well
Is it the joints that cost so much: I've no idea about these things, I'm not having a go or anything! _________________ 1999 3.0 TD Duty SWB

My pleasure!
Now hopefully somebody will come along and tell us both what they actually do: I'm good with engines but the suspension side of things is witchcraft _________________ 1999 3.0 TD Duty SWB

When you lift a truck up the axle is pulled forwards, these arms are adjustable so the axle can be moved back slightly to compensate the lift. They're also a hell of a lot stronger then standard arms so there is less chance of bending them off road. _________________ 2000 3.0 Trooper Duty swb |

Also, with the arms being adjustable you can (by measuring the diagonals) make sure that the front and rear axles are parallel, and with a matching top arm the diff angle can be reset to the optimum. Also with a slightly longer adjustable panhard rod the axle can be re-centred on the vehicles centre line (it'll be slightly off to the N/S after the lift).
Not that I've been trying to justify making a set for quite some time or anything _________________ If all else fails just nod, smile and say "Yes Dear"

Hmmm, sounds like I need some of these as well!
I can see how lifting will throw things out of line now, never given it a thought before _________________ 1999 3.0 TD Duty SWB

But in moving the axle backwards in the original arc, you are also lowering the pinion angle on the nose of the third member, possibly creating stress on the rear U/J, unless of course you also increase the top link by the same measurement, putting all the angles back where they belong. On a 2" lift it's arguable as to whether or not the 5-10mm increased length of the arm is actually needed, but why bother making them adjustable, why not just make them the required length and use standard or poly bushes. They do look well made and very strong however. |

Agreed, you need an adjustable top link too, then you can put the pinion angle back to normal as you say. The adjustment isn't really needed on 2" lifts, so you could make them and use Polly bushes, however the joints do allow for a lot more flex then you could get from non adjustable bars if that makes sense?! _________________ 2000 3.0 Trooper Duty swb |

Sure it makes sense, but the amount of flex is governed by the length of the dampers and even with +2" dampers the original bushes don't bind up, I hope this doesn't come across as negative, you've made a good job of them, I just know how expensive good rose/creeper/johnny joints etc can be. Also with a suspension lift the axle will pull slightly to the near side as the chassis goes up, so the panhard rod ideally should be lengthened as well, but as said on a 2" lift the amount of movement is negligable. |

Just out of interest, did you use rebuildable joints or permanently sealed. |
