Shim.

Shim at RC Shopper: 31 items in stock in the UK. Prices run from £2.75 to £6.99. Stock comes from MST and Avid. Fitment varies, so read the listing for the exact chassis and revision. This is all on the shelf, not on order from a distributor. Before 2pm on a working day means it ships that day. Shims are how you take slop out of a drivetrain without buying new parts. Cheap, and usually the actual fix. Stuck between two options? Ask us. Everything on this page is something we have fitted to our own cars, so the advice is from use rather than from a catalogue.
