    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...

    Isuzu npr 4wd

    Isuzu trucks are all 24V. That said, perhaps in the USA where they are running a petroleum engine, they've also converted the system to 12V; I don't know. We have an American living next door, he was completely mystified the first time I had him in the truck. Manual transmission completely...

    Isuzu npr 4wd

    Isuzu Trucks Australia, and Isuzu Ute Australia, supply all of their vehicles with dieseleum fuel, none of their vehicles are powered with petroleum. Petroleum powered light trucks and D-Max type utility SUV's, are pretty much a USA type of thing. With regard to your tank fitting between the...

    Isuzu npr 4wd

    The simplest way is as our extra tank has been done. Place another OEM identical tank immediately behind the original. This way nothing fuel wise with regard to pumps, filters or plumbing to the injection system is changed; it's also the cheapest. You may have to move the original forward...

    Isuzu npr 4wd

    Hmm, not too sure about that. Our NPS has what Isuzu calls their medium wheelbase of 3395mm, it's turning circle is 13.6m. This is the only wheelbase available for the NPS in Australia, and probably the world. The NPR comes in a few wheelbase lengths, however the crew cab version only comes in...

    Isuzu npr 4wd

    The OEM front axle on the NPS is rated to carry 3100kg, is your front axle equal to that, or is it higher rated? Higher rated, even a little bit may be helpful as your wheelbase seems to be a lot longer than the NPS, possibly putting more weight onto the front axle. I love my drum brakes...

    Isuzu npr 4wd

    I didn't really appreciate this the first time I looked, and now that I've had a think about it, where do you propose to feed the aluminium slats, inside on the ceiling, or outside in a drum? That is a pretty neat idea, seems to be a bit on the small side though. I've just measured my rear...

    Isuzu frame mounted water tanks

    Hmmm, interesting concept. The chassis rails on the NPS which in Australia comes with the Isuzu 3395mm medium wheelbase, flexes like a circus contortionist. If you are converting an NPR into a 4x4, or just using it as a 4x2, and if it has a longer wheelbase than the standard NPS. I would hazard...

    EarthCruiser Closing Doors

    One aspect that may have also helped their demise, is the price of their current base vehicle sourced from Isuzu. While I don't know what price increase(s) the USA market has endured, I do know that the Isuzu NPS model in Australia, has had a 40% price increase from Isuzu just for the cab...

    Two of my nephews have Toyota Hilux Utes, both of them have left their gear ratios as standard, although one of them may change his. Their standard ratio is 32.08 : 1 which reflects that both are running 2.8L diesels. Which may be a reason they are running different ratios to what you are...

    Heavy Truck Recovery Thoughts?

    MaxTrax for recovery boards. We have 4 MaxTrax Mk II full size boards, needed to use them twice. First time was in very hot deep sand, second time was in slimy mud then almost immediately after, a rocky ledge type of bridging situation where we doubled them up to traverse a rock crack. Just...

    Isuzu N-Series front recovery points

    As these vehicles aren't meant for 4x4 work and are essentially a round town delivery truck, I don't believe there are rated recovery options for any of the NRR, NPR, NQR versions. The NPS (4x4 version ex factory) doesn't have any rated recovery points either! This is the rear end of our NPS...

    Isuzu npr 4wd

    Interesting things have happened with vehicle pricing since COVID-19, in general they have gone up quite a lot. Our Isuzu NPS 300 is a single cab chassis manual model, the cheapest configuration possible. The cab chassis was manufactured in 12/2019, delivery to Australia happened (as far as I...
