Make sure you get your pinion angles in the right spot.

go slow.
limit heat/ warping.
one side at a time.
double check all the time to make sure both perches are level with each other.
its a shite load easier if you buy prefabbed spring perches. check the business section on here.

This is true.

I don't usually spam threads but I do a fair few of these. If you remove your old perches from your housings I will glue on some brand spankers for $150 incl. the new laser cut perches. Thats both diffs. :wink:

Offer is open to anyone Armsup

You may need a front tail shaft spacer as the dif moves forwards 5cm if the rear springs are 10cm longer, I used a 2" one to take the slop out of mine.
You will need to consider the wt dif only has 1 rear brake line instead of 2. I just ran one for a while and it seemed ok. (Now I have a rear disc conversion for a NT so I could use both brake lines again).
You will need to move any front bump stops forward as they will not line up with the dif any more.
Read a few RUF threads on how people have extended the chassis/made up new spring mounts and extended shackles etc, there are a few pics and ideas floating around.
Try and get the new perches flat, i reused mine and I can now see buying premade ones would be easier to position and reuse :).
Your NT dif centres will bolt right in, so no flange swapping and slightly lower gears etc.

Enjoy no tyres rubbing on the springs/body!! :)

RUF does NOT move the axle forward 50mm. This would cause the Tie rod and drag link to foul heavily on each other during suspension cycling. And not every spring has its locating pin half way along the spring, so there is no garantee that a 100mm longer spring will locate the axle 50mm forward.

How long are rear springs compared to front springs then? :), and sierra leafs have the locating pin in the centre yes? that number sounded familiar to me :/.

Cheers!

70mm? Can't remember if they are centred or not.

Post subject:  Re: wt diffs into 85 nt zook
75mm and not centred

Post subject:  Re: wt diffs into 85 nt zook
Cheers, not-centered aye, they look dam close. I will have to get out the measuring tape next time I visit my zook :).

You might want to add caster to the front end to counter the affect of the longer shackles and lifted springs. My car runs 5 degree caster wedges as a fix - but if I was cutting the mounts again I'd sort that out.

You could also look at running the rear end wt (I.e. change the chassis mounts to match the diff) as you will have a bit more roll stiffness which will force the front end to work more.
