EU (German) truck speed limit is 80 km/h (49.7 mph), but common speed is 90 km/h (56 mph) because that's what the truck speed limiters is set toEU army trucks usually sit at 40mph in convoy, German truck speed limits are I think 40 on most roads as a max unless on motorway. .
Ha!Sooooo, I learned of something here in Australia that might be a relatively cheep way of gaining more speed for us that need... I helped out a local MB mechanic who looks after a fleet of Mercedes Benz NG's, MK and SK's. He needed o rings and I had what he needed saving him a drive. Anyway, he tried to give me some $$$ for these O Rings, and I said 'nah, don't worry about that, you are my Merc Truck advise man'! He smirked and said no prob.. The conversation continued and we got around to the fact that my truck is flat out at just over 90kmh. I asked how much work it was to 'speed up' the HL7 axles I have... He said "a lot of work, you need a Joey Box". I'd never heard of a Joey Box before but a few years ago it was common to add a small in line 'Joey Box' behind the main box and in front of the rear axle to give older trucks a higher top speed, and also a low box if a 3 speed Joey was specified. I think I have got my hands on a Joey in exchange fore a carton of beer, so will keep you updated on the logistics of what ratio it is, how reliable it will be and the possibility of fitting it between my gearbox and transfercase.

No. I have one in my garage. It is a 3 spd gearbox. Ratios like 2.00, 1.00, 0.73, selected by a shift mechanism.Simon
Never heard of one of these. I assume its permenantly in so it will effect all the gears and you may lose some of the lower ratios.
I will watch with interest
I think you really mean it to have a 1 to 1 ratio, rather than neutral.If it has a nuetral position then i would look to putvit between transfer box and rear axle as this device would only really be needed for 2 wheel drive on the highway.
In 4 wheel drive it could be set to nuetral and all would return to normal. If it has a nuetral.
