JT Sprockets – the World’s No.1 market of aftermarket sprockets.
JT Front Sprockets use SCM415 Chromoly Steel and are fully heat treated. Nearly all cheap front sprockets are only surface hardened. Once the hardened surface is worn the sprocket life is diminished.
Every JT sprocket is made the right way, by hobbing, machining and drilling. This is the only way to achieve the closest tolerances and the best tooth profiles. And every sprocket goes through 10 individual quality control checks before it leaves the factory. That is why we can guarantee the quality of every JT sprocket sold in New Zealand.
Spending $5 or $10 more for a set of quality JT Sprockets, in the big picture, is money well spent, giving you or your customer up to 2 to 3 times the life of your sprockets and chain.
