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

My two-bob's...

I've fitted 2" lifted King Springs (+25% rate) in my D1 3.9, which ended up only lifting it by about 1.5" due to the extra weight of the steel bull-bar and the gas tanks and aux petrol tank. If the shocks are standard travel, you should be pretty-much OK just doing the lift. If the shocks are longer, then I'd suggest you lengthen your brake lines and check axle breathers at full stretch at least. Note that lifting the suspension will decrease your front end caster and might make it a bit more "wandery" on highway. 2" of lift will probably drop the factory +3 deg caster back to around about +1 deg or so. Offset bush kits (typ around +2.5deg) are available (at least in Oz) to increase the caster back to something like factory, but check your front driveshaft UJ working angles if you do this - could be a bit much at the transfer case end if you've got a UJ-UJ shaft. Mine's running the std bushes, etc and has about +1.5 deg caster. OK generally on road, but can get a bit loose in heavy crosswinds, etc so I'll be replacing the front shaft with one incorporating a double-cardan joint at the rear and putting offset bushes in to give me around +4 deg caster - that should make it nice and stable.

Cheers, and good luck :)

Seems to be plenty of slack in Disco flexi hoses, so chances they may not need changing, however, at least make sure you check. Don't forget the rears too.

One usual by-product of lifting a Disco is a pronounced driveline vibration. This will be down to increased running angle of the front prop. Usual occurs on overrun. Cure for this is to fit a Cardan prop from a D2. £200-ish.
