I don't think any of the 4WD manufacturers offer an OEM
suspension upgrade, so there is only after-market.
Depending on your vehicle the range of options could be quite large, and in my experience, there is little reliable advice and much less scientific support to be had on the question of what is relevant to you.
I happen to have good support from a
suspension distributor who could provide their best advice, then see how it worked and then make minor mods to it after that.
Things to take into account:
1. what sort of terrain you are crossing - corrugations, sand, rocks, rock-hopping, roads, dirt, gravel, etcetera
2. what sort of load you are carrying (crucially important), both when you need it most, but also when you don't need it particularly - you might not want to be so highly sprung trying to negotiate the school-
parking lot
3. what sort of clearance you want
4. what sort of clearance is legal and insurable
5. what sort of clearance you don't want
This might include:
1. spring rates for coils
2. heights - largely set by
the springs, but affected by the load
3. camber - largely set by the height and requiring correction if bad enough
4. duty cycles - shockers get overheated when seriously worked out on rough roads
5. protection from damage - stone damage, rock damage, but also ingress of sand and
water
Usually you're making a compromise somewhere.
So, try to find someone who knows what they're doing, and has some real experience - I know some of the ARB Franchisees are in this situation - like Brad Newham at ARB
Gawler if you're in
Adelaide as one example, or Darren McCrea ATS 4x4 if you're in Geeolong, but the bigger the store, and the factory-owned outlets in particular, the less experience, and less knowledge, in my view.
So, work out where you're going ... cross-country can mean different things to different people. Willem or Mick Hutton, for example take cross-country to extremes most people wouldn't even dream about. Then find someone with the real experience - either in the industry or someone on here, who has a similar set up to yours and similar to what you want ... then find someone who can really help you get it done.
Cheers
Andrew.
