    Leaf spring detail isuzu NPS

    They have various, but the ones we have are their budget variant, which so far have been remarkably good. But we are interested in touring to interesting and sometimes difficult to get to places, but not extreme bush bashing, which is what some people in this country do with their NPS units...

    EarthCruiser will be making the 4x4 upfit for Isuzu and Fuso trucks available

    We run MaxTrax standard units. They have only been used once in 5 years, in deep sand. Which was before we had an aftermarket CTIS fitted to the NPS. These days we just press a button, air down more, then drive out. We hover around 6,000 kg and they didn't even flinch. Once we doubled them up...

    Isuzu npr 4wd

    With regard to essentially very heavy duty passenger vehicles with a tub on the rear, as in your Toyota Tundra, then you may have a point; I'm not sure. Here we are talking about a Japanese 4x2 delivery truck that is delivered from the factory as a cab chassis only vehicle with a gross vehicle...

    Isuzu npr 4wd

    Yes and no. If you are talking about a vehicle that will be purely transporting goods over reasonably well constructed roads, then yes, that is a pretty good idea. After all why not make full usage of the larger rear axle componentry, which normally includes 4 wheels on the single rear axle...

    Twin Alternator Setup

    I haven't seen one of these systems in the flesh, but I listened to someone who had one of these systems in their vehicle, which was a food vendor running freezers inside the food van. He was very impressed with his super fast charging system, which if memory serves me, was supplying power to a...

    springs

    Well the reason there may not be much information for you with regard to this picture, is that it is of our Isuzu NPS 75/155. In fact I've posted this picture in one of your threads, and maybe earlier in this thread. Mick.

    Isuzu npr 4wd

    We spent a couple of months in Iceland in 2017 and spent at least double that amount of money. We hired a 4x4 (sort of high clearance) vehicle. One of the problems is that the inner roads/tracks can and will not be opened or closed before you wish due to the prevailing conditions. The road...

    Isuzu npr 4wd

    The standard alternator for the Isuzu range of N series trucks, is 2,160W of power; which is a substantial amount of grunt. Allowing for losses I would suggest the maximum under normal circumstances would be around the 2,000W mark; which is still reasonable. But doesn't account for air...

    Isuzu npr 4wd

    I would suggest it is more important to know the height of your vehicle. Ours is 3.25m and there was a bridge with a 3.3m high clearance sign, so we should have been able to very slowly pass under. Unfortunately due to successive layers of bitumen, the clearance was nowhere near 3.3m, so our...

    Mitsu Fuso Camper examples

    Interesting slide on pod camper, how much do they weigh loaded with water? Is that one of the Austral units? Single cab, so I'm guessing a 4.2m tray? You're game running around with the rear legs attached. So easy to get caught up when doing a U turn in a tight place. My mate didn't rip one...

    Isuzu npr 4wd

    In general I agree with you, however we are in a situation where even the slightest movement, which one can see as the lady steps onto the steps, is unacceptable. We now require absolute steadiness of the steps into the camper, and before you ask, we have solved the issue of getting into the...

    Isuzu npr 4wd

    Steps into a high mounted camper need to be very stable the higher you go. Once over a certain height and if the steps are not standing on the ground, then sturdiness becomes paramount and harder to attain. We thought about doing something freestanding, as in, not touching the ground. However...

    Airbag Air suspension

    DzIToy, I Just had a thought after reading your take on Isuzu NPR/NPS wheel travel, presumably from an American perspective. All Terrain Warriors (ATW), essentially take an everything approach, which you can have, or you can have a restricted approach. In 2019, which is when we started talking...

    Airbag Air suspension

    No we don't have air bags, they restrict articulation and as a result you get wheels hanging in the air way before you could if you didn't have air bags. The 600mm of articulation is this: the top of the tyre rises somewhere between 280mm to 300mm and the bottom of the tyre drops the same from...

    Airbag Air suspension

    As someone who has fitted air an bag kit to a light commercial vehicle, (Isuzu D-Max cab chassis with a tray at the rear) then used it for the last 14 years; it may or may not be ideal. I have actually crawled underneath that truck shown in that video, impressive bit of gear, as is the price...

    Isuzu npr 4wd

    In Australia we have mudguards, which is the aluminium bit in this picture, then attached to the rear of the mudguard we have a mud flap, which can be seen on the rear hanging down. Mick.

    Isuzu npr 4wd

    You don't mention what the compressor is going to be used for, but if you are going to use it for tyre inflation, and most likely to inflate super single tyres, then I wouldn't even contemplate using a 12V compressor; unless it is an air conditioner type of compressor. The amperage required...

    Isuzu npr 4wd

    The major stumbling block for changing to a suspension seat in an "N" series Isuzu cabin, is the available internal height restrictions. there just isn't enough room for deeper seats. The F series, which is the next size up in Isuzu land are almost universally fitted out with Isringhausen...

    Isuzu npr 4wd

    We have Stratos seats in our NPS, they are a single construction, no left or right side, just a damped sprung seat. They are manufactured in NSW as far as I know. Manufacturing time can be an issue as you need to order what you need some months before they will be made/turn up. Personal...

    Isuzu npr 4wd

    Our subframe, to which the tray is mounted, is fully floating; that is, it isn't fixed. This is our tray part way through construction, it is welded to the subframe rails. If you look carefully, you can see the two rails which will sit atop the chassis rails that are welded to the tray frame...
