Collection: BMX Crank Parts

BMX crank parts are the service pieces that keep an existing crankset together and running properly — replacement spindles, spindle bolts, pinch bolts, sprocket locator bolts, spacers, step collars, wedge hardware and other small crank-specific parts.

Most of this stuff is model-specific. Match the crank brand and model first, then check spindle diameter, spline count, bolt thread, sprocket interface and any spacer or collar dimensions before ordering. Two cranks can both use a 19 mm or 22 mm spindle and still need completely different hardware, so close enough is usually not close enough.
