I can help. My 2001 T4 has been lifted (in early 04) to get a bit shy of 180mm under the diff. It is easy enough to do.

Used to live in far north west NSW and have travelled widely - punted the Syncro along the Great Central Road in WA, through El Questro Station (inc. interesting water crossing) and plenty of others besides.

All Graeme needs is a pair of KVRR15 rear springs from King Springs....these are exey for what they are - around $400 but you can order them from any auto shop.

He should replace all the shocks as well. I'm using Koni's but the Bilsteins are fine too. Revalving hasn't proved to be a required item.

The other thing he'll need in a Syncro T4 is some rear diff spacers to lower the rear diff slightly to ensure optimum driveline and CV angles after the lift. Mine are custom fabricated based on the spacers in the Seikel kit - cost ~$75.

Front CV angles don't change that radically as a result of the lift....

First job is to replace all the shocks.

Then, with the van sitting level on a concrete floor, ensure the van is sitting 1 degree down at the front then adjust the front torsion bars accordingly until you get this sorted - this is critical for a long CV life!! Then measure the vehicle height (wheel centre to arch) at each corner and the length of the torsion bar bolts (end to nut).

Remove the rear springs and replace with the Kings. Whilst the OE spring just fell out, I had the devils own getting the new taller springs in. In the end, I had to remove the trailing arm!! It'd be easier if (and require less post fitting adjustment) you could disconnect the CV at the rear diff but I didn't have the right tool at the time.

Go for a short spin to settle the springs in and return to your level concrete floor.

Measure the height increase on the rear.....now you've got an idea about how much to raise the front. However, the measure isn't that critical since you need to adjust the front torsion bars to return the T4 to 1 degree downangle. Which means winding them up....

Now fit your diff spacers. Mine are made from aluminium. There's thinner one at the front and two thicker ones at the rear. They go between the chassis and the rubber mounts. You'll need to replace the mounting bolts as the stock ones aren't long enough (they are M10 hi tensile). Support the diff on a jack, undo the bolts, lower the diff down, slide in the spacers, fit the new bolts, lift the diff, tighten the bolts.

Now that the van is sitting up higher and every thing is in place.......drive straight to your nearest wheel alignment centre and get a full re-alignment as your toe-in will be out by miles!! It is likely that the toe-in adjustment will be almost or to the limit of what's possible.

Job's done...all that's need now is some AT tyres......on 16" wheels this is no drama but a little harder for 15" wheels due to lack of choice.
