I cant claim the intellectual property rights to them.

So hows it all coming along?

The bush is just a normal standard off the shelf item and nothing trick or custom about it. If I break a shock I can replace any of my 4 shocks with any Nissan Patrol GQ/GU rear shock. The shock has a normal aftermarket barpin pressed through the front lower shock bush, and every other bush has a standard 16->12mm metal crush tube in it. It really is nothing out of the ordinary.

ok sunny this is a good chance to ask somehtig that im getting from everyone (meanning suppliers),

i wanted o use kings and konis for a three in lift i my disco,
but they tell me that i would need to get konis made up to go to that height ?? I'm not up for the one off cost of that !, so my q's is to u is could, as your saying, you just go for partol shocks front and rear "straight off the shelf" to use for a three in lift in the disco ???
and if so what am i asking for when I'm going to buy these shocks???, great if you could help!!

cheers

Generally someone is crapping to you as both Bilstein and Koni do long travel shocks that would suit a 3" lift. What you do need to know is what length you require. Depending on shock you may need to relocate your mounting point. Go to Koni and Bilsteins websites and have a look. However they will be significantly dearer. I know to get the Bilstein 7100s was about double the cost of standard. About $900Aud from the US, about $2000Aud out here.
Someone on this site would have done it.
Be aware a 3" lift will be illegal without the correct engineering paperwork. 2" over standard including suspension lift, body lift and tyres is all that is legally allowed now, without inspection and engineering certification. Chances are you wont get picked by RTA / Police but if you do it is a red sticker job, not a yellow.

ok has anyone had the 3" done with king's and koni's? lf so, what was the length (as in mesurement!) reqiured ?, would be a great help.

G'day cucinadio, I really don't kow with Koni as I've never gone down that route - to me they're just twin tubes shocks, but thats my bias. Bilstein do have a shock for the D2 which is 2" longer in the open length over standard, which I understand is standard valved and I suspect it may be (but needs confirming) that they are extended shaft shocks rather than longer bodies. I run the GU/GQ Patrol rear shock in the front of my D2 and that is 70mm longer in the open length, full length body (travel) and valved to suit the Patrol rear obviously with a rate which I understand is 360/80 with a linear curve. That shock rate for a D2 front provides a looot of control.

I guess I would start by working out what length shock I need to run, and to do this you'll need to measure it from the centre of the shock eye to the centre of the shock eye. You can also allow into this however loose you want to run the shock onto the spring to gain a bit more travel, and then compare the free length of the 3" springs to the standard length springs that you have. There isn't a defintive answer as to what shock will suit a 3" spring lift as it depends a fair bit on the spring rates that you chose to run. It's probably also worth measuring the PS springs/shocks as the spring is shorter and you have less interference with the propshaft contacting the Xmember.

If you know what King's spring rates are, then we can have a close guess at what the free lengths are by comparing them to ARB/OME data and making some guess/assumptions. I've got some data on the King 4" lift springs at home (I've been in Sydney for the last 5 days) and those springs have fairly high spring rates which I think were around 250lb/in front and 360lb/in rear (I really will need to confirm). The 2" springs are reasonably soft which are 190lb/in front and 240ish lb/in rear, and so I can only assume that the 3" lift is somewhere inbetween.

If you can use the 70mm longer Patrol shock, then that makes life easy, the only complication is that to balance the suspension, if you have used Patrol rear shocks at the front and rear, then you will need to either revalve the front softer or the rear stiffer depending on your preferences for shock ride/performance. That cost about $150/pr.

My contact is Steve from Bilstein (Sydney shocks/Heasemans) in Sydney. He is excellent, knows his products, is happy to refer to Bilstein motorsports for any modifications to the shocks as/if required, but does prefer to deal face to face rather than over the phone.

All of this said, if you run a shock that is this much longer you will also need to review your brake line lengths F&R, rear ABS line length, Xmember under front prop, check watts link for travel, bumpstops to suit longer shocks, possibly rear swaybar to tweak handling if required.

BTW, all of this is only applicable for the Disco2. The Disco1 runs a different shock setup, but from what I understand Landcruiser shocks work there, but I don't know much about it.
