A suspension lift definitely raises ground clearance, just not on a straight axle vehicle. The front of that Hilux is 2 inches higher with a lift. For the Grenny, not so much.

This is only true for everything which was really 'lifted'. And the axles get not lifted with a changed supension.

More ground clearance below the differentials or the axles in general can only be achieved with a larger tire diameter. And thus the ground clearance (the distance from the ground to the lowest part of the vehicle) does not change at all with a suspension lift.

A 2 inch suspension lift 100% lifts the differential in a IFS or IRS setup. If the pumpkin on a straight axle vehicle is the lowest part of a vehicle then no, it won't change that. But if the front crossmember or skid plate is the lowest part then a lift will raise that. So on the Grenadier it will make no difference. On a Bronco it most certainly does.

That's right, but I thought that we're talking about the Grenadier.

Without that context, I have of course to state more precisely:

And thus the ground clearance of a Grenadier ... does not change at all with a suspension lift.

Or some nice portals...and from Carraro's own marketing literature:

"Carraro has introduced a new range of portal axles, which integrates its traditional range of planetary axles."

"They are equipped with triple-stage reduction with two bevel gears on hub reduction and spiral bevel gear on central section with different ratio
available that allows each type of use and with multiple configurations available."

And the complete sentence prior - which I quoted?

My context was the Grenadier. And even if equipped with portal axles you can not increase ground clearance with a suspension lift.

But if being right is important to you, fine with me:
> More ground clearance below the differentials or the axles in general can only be achieved with a larger tire diameter.

Ok?

It's worth noting that if people are referencing the Grenadier, then the Ineos method of measuring ground clearance should perhaps be used.

It refers to it as "the minimum distance between the bottom of the vehicle body and the ground", so if a suspension lift lifts the body then it will increase the ground clearance.

This sort of circular debate can be overheard in any typical Aussie pub/Sunday session. I’m with @emax on the view that it’s the Marketing types that are to blame, noting that design standards also pointedly differ.

https://unsealed4x4.com.au/busted-the-truth-about-4x4-ground-clearances-and-manufacturer-claims/
That's not an unreasonable view, and my preference for how it's measured as per my portal axle post.

I viewed the ADR wording from your link:

"GROUND CLEARANCE – the minimum distance to the ground from the under side of a vehicle excluding its tyres, wheels, wheel hubs, brake backing plates and flexible mudguards or mudflaps."

but fear it is open to misinterpretation:

Just to be a bit more complete and less selective:

According to Toyota: "the ‘Ground Clearance’ requirement was deleted from ADR 34/04 (Clause 6.4.1) in October 2007".

So that means Ineos are applying the rules the same as Toyota and fully in accordance with ADR?

And not just marketing speech?

@DCPU: I do not know what you mean or how I could help you.

So for the sake of simplicity and out of consideration for other readers, I suggest you are right. :)

And if the Iveco bolt pattern is the same (?) then there's a nice set of steel wheels with 37" tyres:
