"You have no idea what your talking about."
Whyallacookie , If you know of some lower rate aftermarket springs please lets us know , there will be a line up for them, your ARB dealer doesn't know anything about them.
Springs work with a variable known as spring rate.
Put simply , springs are supplied with a rating basically X kilograms causes X compression , lets say that 200 kg compresses spring 1 inch.
Your aftermarket companies normal product simply do not supply springs for cars like Patrol where a lesser force e.g. 180kg will cause a 1 inch deflection.
You can always get special products made of course but your typical aftermarket 2inch lift will need 220 kg to cause 1 inch compression - i.e. they are designed to hold an increased load.
A Byproduct of this is that without this load car springs are harder - i.e. do not deflect as much.
Hence 4wding articulation performance is reduced by most of you normal 2inch
aftermarket kits, but ground clearance and load carrying are improved.
In this exact example I was reffering to one of my setups in which those shocks are a big improvement over the stock unit.
