    What are shims for?

    I was on a rabbit hole and wound up looking at bearings on Avid and looked at other slash products and saw several different size shims like these,

    https://www.avidrc.com/product/5/acc...cessories.html

    What are those used for?

    Can be used to remove slop from some components - such as the differential(s) - or used in places where a bearing face meets a moving or non-moving part (gearbox, bellcranks, etc).

    Avid are my go-to bearings on every vehicle that I have. Inexpensive and great quality! Those shims are great for the screws that go into the top of your shock Tower that go through the shock. Sometimes you need to move the shock out from the shock Tower just a little bit so it doesn't rub and has full function without binding. One or two of these will do the trick.
    You can also add them to any other screw on your truck that you need to perhaps move a turnbuckle out/up like a camber link, etc.

    To piggyback on this , I've also used them on the a-arm screwpins to take out slop.

    Sweet thanks all.
    I’ll probably grab some with some bearings just in case

    It wont hurt to have them. You'll end up finding good uses for them.

    Its one of those things where you wish you had them when you didn't have them when you needed them.

    These are also good to have around as well, especially for taking up the slop in Wheels.

    Losi uses them on their 22SCT's for suspension tuning with their ball stud type steering and camber rods and a arm pivots.

    I use those washers on the shocks as mentioned and the wheels too.
    Tamiya also has some in different thicknesses...

    I saw the other guy said he uses them on his shocks too. Where are you guys talking about? Where its mounted on top?

    Do you put them behind the hex in between the pin and bearing? Or on the inside where the other bearing is? (Towards the truck side)

    This is exactly what I used them for as I raced Losi trucks!

    Yes, both of these if necessary.

    I see several different size options on their slash page, any ones used the most?

    Wheel bearings are probably replaced the most, especially if you frequently drive thru water.

    Sorry, I meant shim sizes what are most used and for what components. The numbers don’t appear to match with the two bearing sizes..

    The basic Teflon washers at 5x10x.5mm as I recall can be used on the top of the shocks on the shoulder bolt to either bump the shock out that tiny bit if it rubs or to remove slop at the shock cap.
    Inside and outside the bearing, if not too tight. I save old ones from rebuilds.
    Some are part worn and some are paper thin and can be mixed and matched to make a snug fit.
    I recently bought some of the Tamiya washers which came in 3 different thickness.
    I bookmarked that Avid page. Lots of shims and washers. May try the bearings...
    I will shim A arms, and any hinge pin really, if I can get one in there.
    They don’t stay tight very long but it’s very satisfying after a rebuild!

    What i did was this: I went on amainhobbies.com or you could google it probably. And looked up bearings for my truck. It showed a bearing kit and said what was included. There ya go. Thats your bearing size. If you want a shim, the last number is your "thickness." So for example, 10x8x4. The "4" is how thick it is in mm. So youd buy a 10x8x.5 if you wanted a shim for the bearing size.

    Thanks that helps.

    I see shims sizes like 10x12 and 3x5, where would those be used? They are not bearing sizes...

    I had it backwards in my last post. It’s 5x10x0.5mm for the Teflon shims.
    First number is the hole size, second is outside diameter.
    3x5 could be used on the large hinge pins I believe.
    10x12 I dunno... The webpage specifies a zillion different models it will work for.
    But I can’t recall anything on my rigs that needs a 10mm holed shim.

    5x8x2.5mm 5x11x4mm

    Those are the two different bearing sizes my truck uses. I have a short course slash 2wd. The last number is probably the same for all the shims. That could be why you don't see a third number. But that's kind of weird as you'd want to know hiw thick they are.


    As for where they go. Thats not a question i know enough about to answer confidently.. Im sorry

    I am however pretty sure that my truck uses a different bearing for the hubs, than the steering bell crank. The 5x11x4 is for the hubs and transmission, and the 5x8x2.5 is for the steering bell crank.

    This is a 2wd truck though. Keep in mind.
