Seeking the most economical place to purchase shims. So far SDI has the best pricing compared to Racetech or MX-Tech, but they are still pricy and often about a $1 a shim. Is there a wholesale provider to get better pricing?

I order all my shims from,sdi. However someone told me a car parts sight can't think of the name right now sells them for half the price. Never looled for myself.

Call your local suspension shop.

I’m always suprised at the cost of them. Just seem expensive for such basic things

I do wonder...just how many suspension shops actually replace all the shims when doing a rebuild?
I know for a fact that RG3 in California do, as do most reputable suspension tuners in the USA, I suppose.
But here in Australia?...Are they rebuilding your suspension with all new shims , or just putting the old ones back in?
Are they revalving your suspension using mostly the shims that were in it and using second hand shims from som e other job to make the changes? I have serious doubts and suspicion....
Someone tell me where Australian suspension tuners get their shims?

The material and machines to produce parts that precise are not cheap. QA1 sells shims in bulk too

You are surprised because you are assuming a simple part is simple to make. Go out in the garage and make one, then figure up a price.

They aren't expensive to produce from a thin sheet metal with a laser cutting machine so in my opinion they are grossly overpriced. Laser cutting machines are pretty standard today in any company that is working with sheet metal. The picture below laser cut shims for KTM swingarm that I designed and had made in my workplace.

How much did your laser cutting machine cost. Asking for a friend.

The older I get, the faster I was.

Take all your shims out of your suspension then go ride and come back to tell me how overpriced they are

I'm not an expert on laser cutting machines but I think you will be able to buy a small laser cutter that will cut thin sheet metal about 10 000$

I use SDI for shims. Just ask that they send them via mail rather than UPS or Fedex or whatever.

Laser cutting is not the appropriate technology in this application. Yes it will work but the negatives far outweigh the positives. Punching is cheaper, faster and you get a superior edge finish and much better dimensional accuracy. Additionally high quality shims need to be made with the correct material and will also need to be tumbled to remove burrs. All of these processes only get cheaper at much higher volumes than a small suspension shop can match. Yes, shims can be expensive in small quantities but parts sitting on a shelf waiting to be ordered costs even more if you think about it.

I'm just curious why doesn't laser cut shims work? Laser cutting accuracy is 0.01mm which is enough in my opinion and edge is smooth without burrs when you are cutting thin material. With punch you need separate tools for different size shims which is more expensive if do small patches but with larger amounts that will be better option of course.

That doesn't explain the high price though. I work as an engineer and I do have quite good knowledge what things cost to manufacture

You need to reread my post. I said it would work and then gave clear reasons why, IMO, the negatives outweigh the positives. You could also make your own chain links with a laser cutter, but again, not the appropriate use of the technology.

Wouldnt it just be so helpful if the suspension companies, Showa, KYB etc, made these available for sale as bulk assortment packs? They obviously have the machines to make these things or outsource to someone that does and I'm pretty sure thatvthe cost per unit is nothing like what we have to pay for aftermarket supplied shims.
Why exactly do they keep these parts to themselves? Why cant you go into your dealer and order an assortmentbof shims for your particular bike?

MX-Tech was my initial go-to, but SDI has better pricing and a more clear website.

I feel sorry for the guy that has to pull the order. Fn shims stick to each other and hard to grab. Then have to shove them into tiny zip lock baggies.
