Thread: Koni Shock absorbers

FWIW I re-valved my 82-2385's years ago, IMO the bump valving was too harsh.

I think I ended up with an 82 14 28 009 foot (bump) valve, but do recall re-shimming several too. (in this case, increasing the stack thickness reduced the pre-load on the foot valve, reducing low speed bump)
Koni call the bump valve a foot valve as it's housed at the end of the pressure tube at the base of the damper.

The bump valve works by metering the fluid displaced by the shaft as it enters the damper body.(eg. in response to a bump, body roll, etc)

Open. 540mm

Closed. 322mm

To go with those
84-1124 RRC fronts.

~530mm open, 315mm closed.

Allegedly rally specials. If you don't have 300lb/in springs and get airborne then these will be way too stiff. With a 4BD1T on top they were still harsh.

I have a molested pair here if anyone wants them. I cut the stone-shields off for access and tried to revalve them but with an oil change went too firm. So I replaced them with the longer 80 series 30-1426 and gave up.
Everything is still there inside, just in the wrong order and with too much preload on the foot-valve.

Koni 2006 Italian Catalogue Here: Read File BASE per Catalogo 2006 - 10 marzo 2006 - impaginato.xls

It lists landrover replacements from 1954 onwards.

I have printed it out as a PDF which isn't searchable and I can't extract text, any way to extract it as the original .XLS?

Currently I'm running cheapy shocks (gu/80 series combo) with lengths of;
Front open 665
Front closed 425
Rear open 650
Rear closed 390
All measured from centre of eye or pin.

I'm trying to find the equivelent to these lengths (or longer) in a heavy track raid 90.
So was wondering if anyone has part numbers for these and open and closed lenghts?
Have searched but no real luck online

Thanks

Damien, you measure centre of eye but from the base of the pin.

That's how Koni and Bilstein measure their shocks and might make those G-Wagen ones look a little more attractive

I've got the Koni Truck catalogue here too in PDF, it lists the open/closed length of every 90 Series they make. Serg found it somewhere and I was only just looking through it. Hopefully its uploaded OK.

Thanks rick, I measured mine centre of bush to centre of bush. Look forward to seeing the catalogue

Rick, had a look through the catalogue which is great. Just need to know what I should be looking for in the bump/rebound columns?
