2" inch lift
POSBORNE:
I`m interested in completeing a 2" lift on my 1991 Discovery, 200Tdi. I`ve got access to the springs & shocks, is there anything else need changing/needing work on? Is it a matter of of putting the new shocks & springs on and away we go? or are there other things that need addressing?
Thanks

this has been covered, in depth, but I'll give you a condensed version, and I hope that people appreciate that the following is accurate, if open to interpretation as to how much they really need doing.
1, By raising the chassis further away from the axle you are increasing the castor angle of the front steering components, a 2" lift will equate to roughly three degrees. What this means is that your wheels are no longer turning at right angles to the road, they're actually pointing forwards a little (by three degrees) and therefore the vehicle will handle poorly, and will often have poor centering whilst driving, it can also lead to some odd wear on the tyres.
2, You are increasing the angle on the rear axle too, but since that one doesn't steer (assuming your bearings aren't pooched ;)) you should get away with it.
3, You will however, assuming you correct #1 be increasing the operational angle of the front UJ (this is assuming you correct #1 with new radius arms), this can lead to vibration, binding and early prop death. The solution to this is either a prop with a wide angle yoke, or, a prop with a cardon joint (it looks like a prop with three ujs on it)
4, You are also increasing the distance between the copper bit of your braking system, and the axles, i.e. you should replace the flexis with longer ones (the rubber hoses on your braking components, two front, one rear)
5, You should probably fit elongated bump stops on the suspension components as they are supposed to operate at a particular point, and your's would be stopping roughly 2" further way than they should.
6, If you increase the articulation on the rear of the vehicle you are at risk of "popping" a spring, viz a viz, the spring dislocating from it's nice housing point, and giving the vehicle a distinct list to one side when you return to earth. There are again numerous solutions, ranging from jubilee clips and relocation cones.
7, unless you get bigger tyres you car is at risk of looking like a rollerskate.
8, your wife will probably complain that she can no longer get into the thing
9, the muddy patch on your trousers that comes from leaning against an open door will no longer be at roughly knee height and will now resemble a rather embarrassing accident

Perhaps this needs to be made sticky, i know this info can be found by searching the site as i have done it, but a lot of people don't search.

TBH one of us ought to wright an article for the technical section, 'cause he's right, how often does this get asked.
