Thanks muc I will look into that , although I don't really know what rate the springs are that ARB supply .
just looking at them the wire diameter looks the same as the original Isuzu spring .
The GVM upgrade is + 270kg , that takes it to the max rear axle rating , so maybe the front springs are just longer .
The mates that have Lovells front Springs in Hilux and Tritons are noticeable larger diameter wire .

if springs raise a vehicle with the original control arms they are stiffer. The stiffer you go the less flexible the irs is . I know how to fix your vehicle and make it far more reliable but it means softer springs (no Gmv) . Besides its almost imposable to load your tray correctly with the original max payload and pluss 270kg with all that load forward of the rear axle . Unless you have full length over head ladder racks and carry timber etc I cant see how you could ever laden the vehicle to need the GMV unless your carting lead .

Most people think 'constant load' rear suspension upgrade is a GVM increase.
It's not.

It's the Second Stage of Manufacture Plate that says GVM is now 3220Kg is what counts .
Because I have a extra 280kg GVM now doesn't mean , I'm a going to carry a extra 280kg
My Ute is a extra Cab Tray , I have a bit more tray in front of the rear axle than a Dual Cab .
I have access to a weigh bridge anytime I want for nix , we have been weighing 4x4s for years ,
I know all my axle weights , Ball weight and Tvan weight . The mates do the same , it's very easy to exceed GVM .
It was a extra $280 for the plate , if done before first rego , it's really a arse covering exercise thats all .
I will look into 30mm longer std rate front springs , just don't tell anyone , mums the word Ok .

Yep, that's what you need for proper GVM upgrade Jacko.
Your factory 2940kg is pretty good, the Ranger is 3019kg, so I didn't worry about GVM, just the constant 300kg rear springs.
I've weighed up before big trips, all loaded with fuel, water, gear and supplies, always 250 - 300kg under GVM.
According to the little weighbridge tickets taped up on the wall in front of me, I take about 350kg extra fuel, water, gear etc on a big trip.

The local recycle place has always let me weight in there when dropping off bottle / cans etc, always good to know where you are before driving for thousands of km.

Utes are pretty well rated n general nowadays, I'd really hate to be dealing with most wagon GVMs, many are fairly average.
In the main, I'd say many start trips over GMV, but soon use up fuel, water etc and get down to the correct specs, you just have to drive to suit, not go silly on tracks etc until some of the weight has diminished.

Keen to see more video of positive changes when you get the extra work completed.

Standard height?

Lifted 2" with Ironman springs n absorbers.

 

[Jackolux]

I have just talked to Dobinsons about a std rate Spring 30mm longer , they tell me their springs are 20% stronger .

 

[Jackolux]

Diff Drop was fitted today , I need to go bush now and with the GoPro next week maybe
Dunno what I can do about a std rate 30mm longer spring all seem to be rated stronger .

Not me... Mines 500kg constant...

How close is the sump plug to the diff drop crossmember?
Did you have underrbody protection plates? What brand? Presume they still fit?

[Jackolux]

I will have to check the sump plug , I did look when it was on the hoist but didn't take any notice .
Underbody protection plates , I have only the original bits of tin , I wasn't going to fit HD plates trying to save some weight
but after having to belt the std plates back into shape to get them back on , they fitted back on ok

I have been researching better plates today ,dunno which ones to get there are a few different ones .
Brown Davis have been recommended , hard to tell without actually seeing them .

Cannot recommend Bushskinz enough. Doubt you could even find a hater (who has actually owned them). They have some good specials on every now and then too. They're probably one of the heavier onea out there but goddamn are they worth every penny in protection.

That's why I questioned why you needed it . I know once you get lighter springs the suspension in the front will more actively compress over the terrain and reduce cv angle you have now .

Something to consider is how protected are the mounting bolts. Some plates I have seen have the mounting bolts exposed which may be an issue with whacking large rocks offroad.

Its pretty hard to damage these . They don't cost much in 306 stainless.

If I had of gone to ARB or any other suspension place and said I wanted a suspension package to carry a Bull Bar and Winch up front , I only have a single hoop Bar , synthetic rope on the winch a tiny 10" light bar , second battery is under the tray and the front axle weight is still just over max rating , They would of used the same front springs , its only a GVM upgrade because of the paper work and the new plate .
So far I haven't been able to find any std rate springs that are 30mm longer

Dobinsons?

Good way to go. They are called "button head cap screws" and are normally high tensile. Though, don't get the cheapo chinese ones shown in the pic..."James Glen" is a good brand.

 

[Jackolux]

Dobinsons?

Dobinsons was the first one I rang , uprated 20% they say .

The bash plate bolts , every service with my Hilux they were replaced if necessary , eventually the nuts in the chassis were the biggest problem , bloody things broke off , I had to weld new ones outside the chassis, lowered the plates a little

actually that's not true , most people would not have sold you a gmv upgrade and mod plate. Unless you told them it was going to be loaded up most of the time and breach the manufactures load . I would have opted for the 60kilo added to a diff drop but prefer the c59-134 and its what I recommend people to buy. It will end your cv busting delemer. it will be standard height again with the winch but with good articulation and flex some thing yours is lacking . But since you have said your buying a diff drop braket the 60kilo 40mm lift would be safe.
