Fastrax RC Washers & Shims for Hardware

Dial in your RC with quality Washers / Shims from our Hardware range. From taking out slop to setting gear mesh, ride height and hub spacing, the right shim makes setup repeatable and reliable. Choose from steel, stainless, aluminium and nylon options in popular sizes (M3, M4, M5; 3–10 mm I/D) and fine thickness steps (0.1, 0.2, 0.3, 0.5, 1.0 mm) for precise tuning.

We stock trusted brands including Core RC, Fastrax, HPI, Associated and Schumacher, with single packs and handy assortments for pit boxes. Tips: match the inner diameter to your screw, axle or hinge pin; check outer diameter for clearance; and stack thinner shims for micro-adjustments. A set of camber link and diff height shims can transform handling on buggies, touring cars and trucks.
