428 Chain Split Rear Axle Sprocket – 30mm – Go Kart

Split rear axle sprockets for go kart 428 chain drive systems. The split design is the practical choice for any rental fleet — tooth count changes without removing the axle, which makes gearing adjustments between sessions or across seasons a straightforward job rather than a half-day strip down.

Tooth count directly affects how the kart performs on track. More teeth gives stronger acceleration out of corners — better for tighter, technical circuits or heavier drivers. Fewer teeth raises the top speed — better for faster, more open layouts. Getting the gearing right for your track makes a noticeable difference to the driving experience and engine longevity, so it's worth having a couple of options on the shelf.

Fits sprocket carriers with 135mm hole spacing and suits most European rental karts running a 30mm rear axle.
