Thread: Classic Range Rover Ride height - Add you measurements!

Don't have standard bumpstops

I think the spring height would be the best but figured it may be difficult to obtain for standard vehicles.
Hence I gave the option for a body line height to ground.

According to RAVE the standard height from under wheel arch (your mythical wheel arch....) is given as 79cm, front and rear.

- Which answers my own comment regarding height and drifitng from 'factory settings'...

So, mixing all the figures up... my guestimate is...

You should have 456mm (45.6cm, or 17.952 755 906") between the wheel arch and axle centres - For Standard Height.

My HIGH Height (Driver presses Magic Button and impresses audience...) adds 40mm to this, making 83 cm from wheel arch to ground (205R16 tyres)

The EAS computer can add another 2 to 3 cm to this, but this last bit is at the whim of the random electrons therein...

you really have got the art of confusing yourself down pat don't you buddy!

Seriously, I'm not confused.... the 79 cm 'standard' height is split between 33cm axle-to-ground, and the remainder axle-to-wheel-arch of 45cm

The first number will change according to your tractor tyres.... and the second will be increased according to how much 'lift' you've got.

In your case, 'cos you've hacked the wheel arches... add 12.5cm to the second figure to take you up to the bonnet seam line. (front height)

Simple !

Hi Grimace,

My RRC suffered the usual bumus sagus (until recently) and researching with vairious suppiers of springs in Perth most said unless you pull out a spring for them to meaure (spring thickness, no of coils etc) or alternative
is you measure underneath from the bump stops to top of axles front and rear all four sides for measurement and they would advise approperate springs to replace existing.

I took a chance and picked up a set (4) second hand springs off Gumtree although I only used the rear springs from the set

My rule of meaure was scientific .....yes the bum end is sagging prior to replacement springs fitted and yippee back end is now higher than the front now

Cheers

Simple !

or alternatively, you could take a tape measure and use it to
a. measure your spring lengths
or b. measure to the body line as requested and report back your specs...

The entire reason I went about it in this manner is due to the fact that I know many have cut guards and custom flares, and also bump stops are modified/replace often as well.

The body line is unmodified on 98% of classics (the other 2% are utes), and the spring perches are standard on 99.99999% of range rovers.

So your input to this thread could have been as simple as 'Hi Grimace, I have just measured the distances for you on my standard EAS equipped classic range rover. They are as follows; 915mm from body line to the ground front and rear. Happy to help'

But assuming it's all to hard I have accepted that the rear is way taller then the front and I will most likely keep it that way.
Now to find out how much the super flex arms are for my application!!!

Hi all,
I've currently got the front of my 1989 RRC up on axle stands (stands are under the axle so the suspension is sitting normally) replacing wheel bearings / seals etc.
I did what measurments I could and got-
Front,
centre of axle to wheel arch - 500mm
centre of axle to the guard line - 620mm
Rear,
centre of axle to wheel arch -525mm
centre of axle to the guard line - 675mm
ground to wheel arch - 855mm
ground to the guard line - 1050mm

With these figures I worked out I have 660mm (26") diameter well worn tyres (Cooper A/T 235/70 R16 on original 7x16 alloy rims), so all I have to do is add 330mm to my front measurments to get the height from the ground.

Front,
ground to wheel arch - 850mm
ground to guard line - 950mm
Rear,
ground to wheel arch - 855mm
ground to guard line - 1050mm

I have 30mm Blue Nolathane or they could be polyurethane, I can't remember now, suspension lifters on the top of all 4 springs.

I don't know about my springs as they were fitted when I got the vehicle but was told they were heavy duty springs from Land Rover, painted black if that means anything to anyone and they have been in the vehicle for quite a while now, maybe 10 years, I am thinking of replacing all 4 with medium duty 2" lift springs and all my suspension bushes to the blue Nolathanes (blue's softer then red).

I'm still unsure what the factory measurement are meant to be so I don't know how much mine has been raised.

While we are on suspension height I was told you need to replace your radius arms to restore your steering caster angle, are there adjustable radius arms out there or are you locked into a height because of the height the radius arm is made for.

One last thing not on suspension as such but I'm looking at a set of Mickey Thompson Baja Radial MTZ tyres in 265/75 R16 would these fit on the RRC's 7x16 alloy rims or are they a bit big. 265's are usually on 7.5x16 and bigger rims.

Cheers,

Hi Valguard, I to am not 100% on the factory measurements, but I believe the front end of your is approx 2" over standard (closer to 40mm actually).

With that given lift, you do not need to adjust your castor, but you still can should you choose to do so. This can be achieved via castor correction bushes, alternatively you could have your swivel balls elongated (adjustable to an extent), or with replacement arms that are made to suit your lift application (not adjustable).

Those tyres would be fine on a 7" rim, I intend to do the very same to my discovery 1

Hi Grimace,

RRC 1981 2 Door

Ground to wheel arch Rear 875mm
Ground to wheel arch Front 845mm

I run 31 x 10.5R15 tyres on turbine mags if that makes a difference.

Cheers
