Ok
I have the CRDSTU H/Duty lift
measurements from ground up through the centre of the tyre to the bottom of the guard
Standard Height & Standard 245/65/17 tyres
Front 845mm..... Rear 840mm
CRDSTU lift with standard tyres
Front 890mm..... Rear 910mm
Front 45mm increase Rear 70mm increase
With my 2t van hooked up it sits level and I didn't needed the WDH on my last trip to QLD (5000km)
Currently with 245/75/17 tyres sits at
Front 900mm...... Rear 920mm, an extra 10mm from tyres.
I am contemplating changing my rear shocks to allow more travel, but I think the 5 link rear setup is the real limiting factor, may just change out the HD springs.
