So why is it that the suspension shims are so expensive? Are they different from the ones you could buy in a hardware store (they only cost like 15ct per piece or so)?
$1 each might be a lot for a little bit of metal, but it only adds up to 10 or 20 bucks for a full revalve. If you can buy the variety of shims you need locally, and they are good spring steel, go for it. I have not been able to find any other sources for shims, besides the suspension suppliers.
You don't get the point. I'm just asking if they are different. I'm not using them, and wouldn't want to if they are different. As long as the steel is of the same grade I don't see the problem. I'm led to believe they are just the same, although most hardware shops wont have them that small. Just asking...
I have never seen a hardware shop carry a variety of different diameters for one given ID and thickness. Usually you only get one OD for a given ID. Suspension shims (for cyclical bending) are usually made from one or a few very specific materials for that purpose. Shim washers (for spacing) don't have the same requirements, so they may not be made from an appropriate grade.
During my younger years I purchased all the fuel, hydraulic and pneumatic components and misc hardware for a (Northwest Airlines) commercial airline fleet.. and I can tell you those washers are VERY cheap in comparison to FAA certified fasteners and hardware.
Went to a local suspension shop, they were selling shims for 4,20euro per piece that is (about 5,70usd), thank you but no thanks!
