Sold as a pair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eA pair is one axle.\u003c\/strong\u003e Front and rear do different jobs, so you can order a different spoke count or durometer for each — add one pair for the front and another for the rear. Two pairs covers the truck. Mixing durometers across axles — softer up front for grip, firmer at the rear for drive — is exactly what the pair split is for.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpoke Count\u003c\/strong\u003e is the number of chevron arms — and the number of grip grooves on the outer edge, which always match. Fewer arms give more compliance; more arms hold shape under load.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInsert size\u003c\/strong\u003e is set by your wheel and tire together: the wheel determines the hub the insert seats on, the tire determines the cavity it fills.
