Bump stop clearances

[walker]

I remember reading somewhere that the Bumb stop clearance for the Range Rover Classic was 2" (50mm).

Does this sound correct?

Should it be the same back and front?

thanks

LRA used to have some blurb about it

All my rangies are modded. I guess you need this for engineering? For what year and model? I have told my engineer same as Defender 130. Wider track etc. I have RRC specks here if you want them. Most springs work on colour Code. Free length, Rating and No or coils.

Yes, I will need it for engineering. It is for a 1987 Range Rover. I have a feeling I might be a bit high, but I will wait until I get all the bars and rear tray on before I make a decision.

They were different for various years. Landrover played around with them and you could also get a HD option. These sites may help you

Basically you should have blues in the front and pink/purple in the rear for an 87.

Also the springs were designed to have a load leveler in the rear to take some of the weight

Hi,

The info is here:

Outer Limits 4x4 Board :: View topic - FAQ Tech Info (Bible) (http://www.outerlimits4x4.com/phpBB2/ftopic13961.php)

says stock RR is 2". About 5" on mine. One way around this is for the engineer could be to fit extended bumpstops from Equipe or Paddocks.

cheers, DL

Front standard 50mm, rears 70-75mm

Ok, thanks, but none of that helps. It is not the springs that matter but the bumpstops.

For engineering, we now have to follow the new national regs which means a max lift of 150mm. This includes spring lift, body lift and larger tyres.

Since the engineer will only engineer for 33's that means the tyres give me 50mm lift. I have a 50mm body lift which means I can only have 50mm spring lift.
Since EVERYTHING has been modified I cant use hub to guard measurements anymore, but I can use bumpstop clearance.

I was pretty sure that standard front bumpstop was 50mm which means I can go to 100mm, but I was not sure if the back was the same or if there was more clearance.

I cant find any bumpstop specs for a standard range rover anywhere.

i have 52mm front and 68mm rear written down here as std RR bump stop clearance.
unsure where i got this from though, copied off the net somewhere along the line!

Thanks to both of you. That is the exact info I was after.:)

An observation:
My (genuine) workshop manual only gives a minimum for the back, and this is 67mm. My '81 RRC has a front clearance that looks to be pretty close to 100mm (raining at the moment so I don't feel like actually measuring it).
The car used to sit level before the rear springs sagged. Front springs (fitted 27 years ago after I fitted an ARB bullbar and 8000lb Warn winch) are HD and I threw the box away a couple of years ago so can't say for sure what make. There is enough travel to smooth speed bumps right out. The faster the better.
Ideally I'd like to get that 4" clearance on my Disco 2a, as long as it doesn't look like it's on stilts.

Further to my previous post, the 67mm rear bump stop measurement is the minimum distance with the suspension at rest and the levelling unit relaxed. After giving the Boge some work so that it pumps itself up, the minimum should be at least 20mm more, i.e. 87mm. So I guess the correct operating clearance for an '81 would be just that ; 87mm.
By the way, when I fitted the HD springs (lime green in colour) 27 years ago I also fitted OME gas shocks all round. The gas pressure is long gone, but the shocks still seem to be operating OK.
