Available in three driven gear options — 36, 37, or 38 teeth — this single gear change lets you shift the balance between top speed and off-the-line acceleration without splitting the cases. Fits both A-block (54mm) and B-block (57mm) GY6 engine families.

Pair with a big bore kit or performance exhaust to make the most of the taller ratio. If you just want a mild bump in top speed without sacrificing rideability, the 37T or 38T is the safer choice.\u003c\/blockquote\u003e","brand":"NCY","offers":[{"title":"14x36","offer_id":68033454342465,"sku":"1200-1059 14X36","price":62.0,"currency_code":"USD","in_stock":true},{"title":"14x37","offer_id":67964595011905,"sku":"1200-1059 14X37","price":62.0,"currency_code":"USD","in_stock":true},{"title":"14x38","offer_id":68033454375233,"sku":"1200-1059 14X38","price":62.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1011\/7785\/2225\/files\/1200-1059_a_b45f0bef-a72d-43ba-8951-03d4b5693715.jpg?v=1792809184","url":"https:\/\/azscooterparts.com\/products\/ncy-gear-wheel-1436-37-38gy6-magento-8937","provider":"AZScooterParts","version":"1.0","type":"link"}
