    Default NPS 300 Crewcab questions

    Gday Overlanders,
    I have recently purchased a 2010 NPS 300 Crewcab 4x4 with the view to setting it up as a capable long distance tourer, I have a Rubicon with all the fruit as my weekend warrior, but as a long range remote tourer it is far from ideal. As such i want set up this truck however i need it as a big ute still for work purposes so will run a slide on camper such as Carry-me camper or similar. I have spoken with the fella from Goanna tracks with regard to Supersingles and have been doing research regarding suspension. I read mixed reviews regarding Parabolics and have seen the youtube vids from SSA. I plan on building a new tray as the 2.3m x 3.6m currently on there is enormous and impractical offroad. So i guess what im looking for is some advice regarding making this truck ride nice enough to keep family happy on long runs and be as capable as possible to get to the good spots. Ive got a reflash organised which will sort out future EGR and DPF issues along with a healthy boost in output.
    So please give me the good oil to save me wasting time and cash. Meanwhile ill keep reading the endless threads and try to absorb as much as i can.

    Thanks in advance
    John

    Hi John, Welcome to the journey!

    There are many opinions around on suspension/wheel choices for these trucks. I went with the ATW springs and Alloys and very happy so far. The comments from SSA about parabolics refer to OEM versions and can't be translated to the aftermarket ones like ATW, also be careful with wheel choices, when I spoke with Mr Goanna Tracks about his they didn't come with any approval for fitment to these trucks, he said he wasn't going to spend the $$$ needed, not sure if that's changed but his site still says' fit at own risk' or such words, although I know some people have had them individually approved with a friendly engineer.

    Just one of the countless decisions you will have to make with this project.

    Cheers Steve

    Hi John , I am currently setting up my 2013 nps and have all the same questions. When I spoke to Kim Bolton regarding his wheel and tyre combo he was waiting for approval from the heavy vehicle regulators to have the setup certified, within the next few weeks he hoped. I think I will go this option for wheels and tyres, as I think from a bit of reasearch that they will be a bit better in the sand and mud. Happy to hear anyone else's opinions of this, also interested to hear if anyone has the SSA suspension upgrade and how it performs compared to standard.
    Cheers Brent

    I read one of the threads on here regarding flipping rear shackles to underside of hangers like normal vehicles using longer leaves, this gave a significantly softer ride with greater articulation. Has anyone else done this? Im keen on SSA kit as its very cost effective. Front springs longer leaves more camber giving softer ride and clearance for 37" super singles were about $450 each half the price of an oem spring. Ive never owned Parabolics but have heard and read of many breakages and only one manufacturer in OZ would make remote dramas harder to repair.

    Im currently fighting with a hunting at idle, I believe it is the suction control valve but will hook up to diagnostic gear at Injection shop to test before i start throwing parts at it.
    I have 2 of these trucks one I am selling to fund the camper build. Its up on Gumtree if anyone is looking for a Truck.

    Many on this forum have replaced their stock front leaf springs with longer version. In my case, it did make the ride much softer (along with BFGoodrich tires 315/75R16 with Alan's rim). Beside SSA there are other players in this work like Carrolls, Dobinson, (etc?). I went with Carrolls in Brisbane (they have shop at Sydney & Melbourne as well). With Carrolls bump stop gap is about 40mm and so far haven't noticed any bottom out on rough tracks. Hope this will help.

    And welcome to the forum and wish you good luck with your build

    That's good news Cuddy, I was keen on Kym's setup initially but the non approval was a deal breaker.

    As per lots of choices with these trucks, it all a compromise.

    Cheers Steve

    Has anyone got an off the shelf suspension setup thats proved itself or is it just a case of getting your frankestien on and experiment?? Ill build the new tray using kinetic mounts however i plan to mount towbar and rear winch, so can i hard mount at rear of tray as towbar and winch plate will be tying the rails together anyway? Or am I missing something?

    not sure what sort of proof is required!

    is from Europe via Morocco and Kyrgizstan/Tibet to Aus, then recent Aus trips, sufficient? ATW parabolics +SRW with Toyos.

    First shocks lasted about 3,000 km. Second (Monroe) shocks the rest of the way to Aus. Current look like lasting well after corrugations and desert. The Konis (softer compression harder rebound) added an extra bit of comfort. Recently replaced worn rubber bushes with polyurethane/greased - stopped the squeak.

    I only have experience of the one setup so difficult to compare. Modifying anything and building one-offs can be fraught.

    Don't know about winch. We don't have one. Wouldn't have been much use the time we fell off the road.

    Really all depends what one is trying to achieve and where one wants to go.

    The towbar should definitely be mounted to the chassis rails, as should be any winch.
    My attempt to build something to go somewhere else...
