Spring rates for a RR

[walker]

Hi all,
I just wanted to get an idea of what spring rates everyone is running with a 2" spring lift. So far it seems the majority are running 180lb front and 210lb rear. Is anyone running lighter?

I would like to run 150lb front and 180lb rear and get them custom made for height, do you all think I am asking for trouble going this light?

Lastly, is a 2" spring, 2" body lift & cut guards enough to run 35" tyres. I have a '77 2 door.

Thanks

you will fit 35"s easy with that setup

i was running 2" spring , 2" body and flared guards and my 35" pedes very rarely scrubbed out

also speak to shane AKA 4wd Stuff on here , he was a lot of help with my latest spring lift and hunt for shockers

But more importantly, what spring rate?

[HSV Rangie]

I run

180 on front

270 on rear.

Have a look in FAQ lots info on springs ect.

Thanks Michael,
What do you have in the back for such heavy springs or is it for towing or touring?

[HSV Rangie]

220 s were to floppy. Also when loaded for camping sagged more than I wanted.

Have rear bumper and rear spare wheel carrier.

Ok, this is the sort of real life data I was after.

I also have a rear wheel carrier so it sounds like 180lb would definately be too light. But I do want to get that very soft feel that the original Rangies had.

i also run 2" spring and 2" body with heavy chopped guards, but my 35's still rub on the rear of the wheel wells.... TBRI custom wheel wells on the way

Whats wrong with an angle grinder & a sledge hammer.

I ran 180 lb springs in the front of my 2 door and 220 in the rear. Even with a load and ARB bar and spare wheel out back they were ok. Found that 270 lb Rangie Spares Springs were too harsh. I also tried a set of Lovells springs at around 240 lb rate which were good in the rear. In my 4 door I have 180 lb fronts with ARB bar, dual batteries and winch but at the rear need 300-340 lb variable ARB springs due to the ARB bar and wheel, heavy aftermarket tank and all the tools I carry for work. The rear is much too stiff unloaded though. Seems that the 4 doors are heavier in the rear and Rangie Spares confirmed that.

Ok,
seems that my idea of 150lb & 180lb will be too soft. I guess I will stick with the majority & go 180 & 210lb.

I am a bit surprised as I have my 2004 Disco lifted 2" & I am only running 150lb on the front even with bar & winch. They are custom springs & were made 2.5" taller than standard & gave me a 2" lift. They are perfect and I would not want any harder.

[landy_man]

you dont have to go with the majority...
why not pull your springs out the disco and fit em up and see how the go...
would only take a little while to change em.. if you're happy with 'em get some made
nothing ventured, nothing gained

I was wondering how people with the higher rates went for flex?

Can you get full articulation at 270?

I know this would depend on load but at 270 can you only get good articulation when carrying 3 people camping gear etc?

This site has a little list too http://www.rangerovers.net/rrsuspension.htm
Approximate Coil Spring Rates (lb/in) (Front) (Rear) Swaybar bushings
Pre-EFI Range Rover 1970-84 133 150 no soft
RR Base Models 1984-92, County 89-90 133 120-178 (variable rate) no hard
RR County 1991-93 133 150 yes soft

I found my rangie was much to close to bumpstops after adding a winch, winchbar, and steel cable
Since firming up the front to take the weight, it doesn't flex as well. (No surprises there.)

I remember reading an article about the Smiths rangie, and they were changing the rear springs based on the event they were going to!

I feel the 270 s are slightly to hard.

what I want is 250 I think.

These i will have made by jacob springs Melbourne.

220 were ok just to floppy empty and sagged way to much when fully loaded.
Lost 35-50mm when loaded.

180 in front with holden motor and steel BB seems to be good.

I have since found out that the Rangie I just bought already has 180lb front & 230lb rear and has 3.5" front & 5.3" rear at bumpstops so I will probably leave it as it is for now. It also has Bilsteins all round but I will have to try and find out there length.
