Superior sent me 30 mm bump stop extentions but I have found out that I need new bump stops so I don't know if I should use the 80 series extended bump stops and sell my extentions or buy new patrol ones and keep the extentions, the 80 has progresive bump stops so the impact is softer

i have the 80 series ones in mine on a 4inch lift. Seem to be ok. Mind you, I'm no hardcore offroader.

[emoji848] I like to think I'm no hardcore offroader as I've got a 0inch lift!!

I have these from Superior but they’re unlikely to touch with the way I drive now..
I use the stock stops in the front because I can’t be bothered pulling the springs out to fit the longer units.

They’re Polyair bags that I bought just before I put the 500 kg springs in for the GVM upgrade. I put them back in but they don’t do anything now. I just leave them at 5 psi.
I have a 260 kg ball weight with the van on and the springs barely compress so bags are not needed.

Mine was pretty straightforward, engineer gave me a list of what he wanted done and let me do all the work.
I had to use the springs & shocks he dictated and do the castor correction as well. He came to my place to check it all and fitted the blue plate.
Nothing complicated at all, I now have 3550 kg GVM.
One of the strange things I had to also do was swap out the side indicators for cat 6. Something to do with it now being light commercial category.

Well I have a Gq and the first thing I had to do was swop the front and rear diff assembles and that right there is where is already fell appart, I got a set from the wreckers late Friday afternoon for $1500 and when I got home and inspected the diffs the front diff was a write off and the rear diff one side of the bearings was shot, wrecker warranty is a joke and to top it off he is not close and they will not do anything unless you go there, in hind sight it would off been better and easyer to buy off the net and replace the diff centre, I had to spend more money on buying a diff housing and brake calipers and rebuild the diff with a new swivel hub kit, so that was just the diffs my suspension kit must of been put together on a Friday because not only were the wrong parts sent but parts were missing and I am still waiting for the right parts to turn up I swear there must be a tattoo on my head saying please rip me off and screw me around
