hello
I would like to upgrade my 2000 land Rover Discovery II SE
by installing:
RTE 3" suspencion lift
Rancho shocks
and BF Gooddrich 285-65 R18 All-terrain tires.

And my question is
Would the suspencion lift affect the Drive train and the speed on the highway?
and also
Do i have to change the Gears on both axels?

Speed and gears both depend on the size of tires you put on.

New tire eight, divided by old tire height, multiplied by stock gear ratio, will give you the gear ratio you should run to keep your stock power curve. They say that you can go up to 10% over stock tire size without the need to re-gear. But with the 4.0L being as anemic as it is, makes me think that the biggest one should go over stock, is 5 %. Therefore, A 245/75, or a 265/70 should be the biggest size to go before re-gearing. It also puts less stress on the driveline andbrake components.

Also,the wind resistance is more and more present, the higher you lift.

 

Rancho shocks are junk. Get some Old Man Emu. I have seen several Rancho shocks pop on Jeeps and they are loads lighter than a Disco

 

As much as I like the RTE suspensions, their 3" lift on a D2 will add nearly 4"s which means, new brake lines, ABS lines, new front and rear drive shafts and front radius arms.
So why did you want this lift?
The only shocks that would work with that lift would be the 7100 Bilsteins at $200 plus a piece.
As for the tires, are you ready to loose 2 to 3 MPG with that large a tire.
As for the gears, your diffs won't hold up to that much tire for long which means you will need to add the CDL, two new lockers and to offset the gear ratio, 4:11 gears.
You will be looking at at least $6000 for this sort of set up.
All that being said, lets see what you are really wanting to do with this truck and how much 4 wheel experience you have?
Get back to us and based on what you plan on using the truck for, we can point you in a better direction.

 

well i just bought this 2000 Land Rover Discocovery Series II SE
im the second Owner.
I dont know nothing about Land Rovers.
The car that i owned before this one, was a 1990 Jeep wrangler
4" Suspencion Lift
2" Body Lift
35" Bf Goodrich AT
custom front bumper with 9500 winch.
Diff lockers
and much more.
I sold it becuse i love the features and Looks of the Discovery.
I just whant my car to have a good ground clearance and more. I care to much for this car that i dont whant nothing to happend to it.
I Contact Rovertym Engeriering and
they recomend me the 2" Suspencion Lift.
Wha do you Guys recomend me?

 

As I mentioned before, the RTE 2" lift or the Old Man Emu lift will both get you up to nearly 3"s
Still kind of curious what your are going to use this for, what sort of trails?
Are you ready for the expense of wheels, tires, the lift, drive lines, lockers, gear ,axles bumpers, sliders, diff guards and all the other stuff?
I wouls suggest you bite of a little at a time and see what your Disco is capable of and then modify it as you go.
Not what sure where in California you live, but there are a couple good Rover clubs, that I would suggest you go out with, see what other people have done to their truck and what they can now do.
Just a thought, I have seen so many people who also new little or nothing about a Rover, throw lots of parts at them and find they didn't end up with what they really wanted or needed.
As mentioned before, forget those shocks and goo for what yours well on a Disco not on a Jeep.

 

No matter what lift you do, after it's 'done' take it in for a computerized alignment and have them measure the castor angle. Mine after a 2" RTE lift was out by 1.57% and 1.67% which is enough to cause handling issues. I'm debating now if I want to correct using cranked arms or to cut and rotate the diff housing. With more than a little correction you end up getting driveline vibration if you try to bring it back to within spec, RTE arms usually only correct 'most' of the error for this reason. I'd talk to Steve and decide on something. If you're going 3" and plan on a bumper/winch I'd skip OME and go with Bilstein 7100's if you can afford them, they're rebuildable and tunable which is a good thing long-term. Doing the job twice always sucks.
