Thread: Tweaking an Army 6x6

The 6x6 are over 3 Tons, you need a LR licence, they run 4.7:1 diffs and have low boost on the turbo.

First thing you would change the diffs to 4.11:1 ratio and then up the turbo boost pressure/change the turbo for one giving more boost and add an intercooler.

They are exxy on rego because of the national freight charges.

As Diana said, faster diffs, better turbo, intercooler and fuelling. There are probably also a number of ways to shed weight. Dougal has a thread with a huge list of turbo options.

In addition to that, apparently you can derate the GVM to save rego costs. To help with this you can slim down the spring packs quite a lot to save weight and make the ride much more supple offroad.

The existing rear springs require 1.1T of load to deflect the suspension 25mm.
So 3-5 T until you hit the bump stops!!!

Off subject and somewhat random I know but if you need a LR licence to drive a 6x6 why do the bikkie dippers that clog up our roads with Land Cruisers that weight just under 3 tonne and caravans the size of Cathedrals only need a normal licence.

Amazing

They can't be loaded up to 5.6t.
It's all based on GVM. Vehicle weight and load.

My Discovery 4 is in the same situation, although I have a HR licence.

Thanks for your thoughts. I Hadn't considered the implications of the vehicle being classified as a light truck. OK for me but wife would need to sort her licence out to drive it. Other more serious issue would be no dropping into the local for a coldie on the way home after work

123 Rover 50... has a 6x6 that has had the cab moved forward to forward control. Has a double bed and kitchen in the back a V8 diesel up front . Its huge and the only one like it in the world. You may be able to PM keith and get him to post some photos. Its a magnificent vehicle.

You would also need to use a log book.
