Friction Discs for AH 506 Shock Absorber

DavidThompson

Anyone know where I might get 506 2.5mm friction discs?
Although these are advertised on the Sports and Vintage web site, they turn out to be c3.5mm.

Hopefully the above links might be useful to others, but not to solve your problem!

I assume Sports and Vintage are not able to supply a ‘special order’, if you require 2.5mm discs, one would think others would too!

These appear to be made from wood. Why not make your own?

Sports and Vintage show 2.5mm on their web site, but supply 3.5mm instead. S&V say this is because they are no longer able to get supplies of 2.5 but have not altered their web site.
NDR seem only to offer complete units, and Benchmark only offer 4.5mm.
The issue is not insurmountable as the shock absorber will accommodate the extra width, but it will mean replacing the centre bolts. However, it seems i will have to use BSF which I would prefer to avoid.

I suspect that this is a foolish question, but could one take the 3.5mm versions and sand them down, or perhaps in a lathe?

I cannot see why not, but I would first try to find out exactly what they are made of, and if there’s any chance of asbestos in the material forget it.

Cheers

They used to be made from lignum vitae, but I believe that these days a type of hard fruit wood is more usual.
It astonishes me how long it lasts, the current set in my car are still fine after about 60,000 miles.
