is it necessary???

Adrian,
Previous posts say caster correction should only be necessary for 100mm ++ lifts. Lots have 50mm with no problems. Roachie may be able to provide more detailed advice

Adrian,

It is quite likely that you will have to do the castor/camber. As you lift the vehicle, you change the angle & it will pull, most likely to the left.

By way of illustration, I have not lifted my GU, just got HD springs & shocks. I have a 3/4 degree kit fitted in the LH side, and a 4-Way brand, return to center damper. Its OK now - the damper was the best bit. Use this brand as they have an external helper spring that the other brands do not.

If I could offer an opinion before you purchase?

try Alltrac, on South rd. It is likely they may not charge a fitting fee if you buy all the gear there, - they fitted RidePro shocks for me at 80,000 km service for nix - one hours work free. I am v happy with RidePro performance & price. I currently have TJM HD springs and am consifdering goinfg to a 2 " lift, with RidePro springs & camber/castor mods as necessary, all done by Alltrac.

I have no beef with TJM or Arb, BUT these Alltrac blokes leave them for dead with knowledge, cutomisation & expert fitting. Guess how I know.....yeah, the hard way. I now do not consider going anywhere else.

good luck

Hi Adrian,
I had the exact same problem with ARB Dandenong. My wife and I live in central Vic so we are a fair way from most places. We rang Dandenong about our lift kit and were quoted what we considered to be a reasonable price, only to drive all the way down there (2 hours) and be told the same as you, that we then needed the castor correction kit, steering damper etc. I always intended fitting it myself anyway, so just bought the bits that were within our budget, and figured that if I needed to fit a castor correction kit I would do it at a later date. So far our vehicle has not needed it and remains fairly constant on road at all speeds. I'd be fairly dubious as to the price they quoted you, as if you look in the ARB book from memory the castor correction bush kit is only about $130, so $500 of labour just for that seems awfully high. To be absolutely honest with you I'm reallybleepoff with ARB and TJM as every time I've rung them for something on the car, I've only had to go down there to be told I needed something else. Two examples, I wanted to buy a winch and have a winch bar, only to be told when picking up the winch I'd need a winch carrier; another time I wanted a Kaymar rear work light, only to be told when I got down there that I then needed a special bracket for it to be fitted to the car. In short, don't listen to the sales pitch. Talk to those that have done it/got it.
Cheers

My gu has ome 50 mm lift no need for the extras at all but i found the new springs quickly "settled/sagged" so after a while you dont have 50 mm lift, maybe your supplier should guarentee 50 mm lift after say 6 months,wish i had thought of it at the time,after all original springs dont sag after 3 months to same degree.

50mm lift you need 4 shocks and 4 springs. Thats it.

I put OME coils and nitrocharger shocks on the GU when it was brand new. The price quoted by ARB seems about right.

I had been told by a local ARB outlet that I would need castor bushes. The main ARB store in Perth (Osborne Park) said no way....not required. The lift ended up around 75mm rear and 50mm front after install and then settled. I have not required castor bushes but the steering damper ($100 ish?) was fitted with the suspension and has been very good.

I did not know what spring rating would be suitable so ARB said no problem, fitted medium rating and said if they aren't suitable, bring them back in a week and we'll put on another set at no extra charge. The mediums were not suitable and I ended up with the heavy rating.

I call that good service all round.

Have 100 series. Replaced springs with King Springs. Consult their advisory service see free call number on their web

Went 50mm and measured free length of the original and new surprise the new springs are actually 10mm shorter than the original so i then used the original shocks until they die as the free length is less than orig.
When they die will look for other shocks

So far very happy and much cheaper than other aftermarket jobs

the truck now sits a little above original height but will take a decent load

Did the same excerise with an 80 series and had no trouble in 10 years of travelling
