GU lift...how high before other changes?

Andrew
You can do 2inches (50mm) with out having to change anything. Above that you may need to do offset castor bushes, above 3 to about 4 inches you may need to extend diff and brake lines and extended shocks.

Ran a 3 inch dobinson setup with no castor correction. Drove like a dream. Did extend brake lines and diff breathers. Brake lines did not need to be done, but I knew I'd jack it up further sooner rather than later...which I did. I installed the kit at 800k's on the clock. A 200,000k truck may need castor correction with all the extra wear.

3 inch is a great lift on the GU's. 31's look great, they sit well and still handle relatively well. The 4 inch extra heavy duty lovells kit with EFS shocks on the GU were perfect. I also ran extended sway bar linkages, 5.5 degree castor correction plates and adjustable panhard rods. I payed under a grand for mine but that was from my mate who owns a fourby shop.

I can recommend the lovells/EFS combination as I ran it in a GQ as well for 100,000.

Cheers,

Chris.

Hi Andrew,

I have a 04 model GU, and installed 2 inch lift using OME shocks, and was advised by the installer to also install casters.

I got the casters installed and would highly recommend them. We have even tyre wear, and a good feel of the steering.

Hope this helps

Thanks

I had a 40mm lift on my 80 series and had to get the Castor kit (as well as a camber kit) fitted; however, it was possible that it was due to the age of the vehicle - a 91 model.

My personnel thoughts though if you are going to alter the vehicle from it's original design ie the lift kit then you should really consider the castor kit and get it done all at the same time. Rather than later on and costing more money.

Hi Andrew,

Have a look at my rig details, in my case the castor correction kit ( bushes only ) was needed, tried running without it and didn't feel real good. Had a series 2000 setup in my LWB GQ, IMHO the setup I have now is far better. Keep in mind the way you see it in the rig pic the whole lot weighs 3t plus, and I stuck in 2x30mm spacers in the rear the night before we left to have it sit as seen here.
If your sticking to under 2 inches you shouldn't need any of the extra stuff except maybe panard rods. Note the "should" & "maybe" as most patrols are finicky to suspension changes at the best of times.

Hi,

50mm would result in very little additional requirement to modify/replace your panhard rods, steering drag link, castor angles and swaybar linkages. Pretty much anythng beyond 50mm will require more mods to get it right.

Anyone knows what happens if you go over 50mm and don't touch the other bits - castors etc?
