Swingarms, axles, and spacers.
The only difference between chain and belt drive swingarms is that the belt drive swingarms are about 3/8" wider than the chain drive swingarms. Apart from measuring the width, belt drive swingarms van be distinguished form chain drive swingarms by looking at the shock mounts. Whereas the chain drive swingarms have two identical mounting blocks, the belt drive swingarms have two slightly different ones; the left shock mount block is narrower than the right shock mount block and sits flush with the outside of the swingarm whereas the right block is protrudes slightly beyond the swingarm.
