Self-cleaning tooth design increases chain life and reduces sprocket wear, saving you money in the long run
Manufactured using only the finest grade of SCM420 chromium-molybdenum steel alloy to outlast mild steel or surface hardened sprockets
Each 520 countershaft sprocket is heat treated then bead blasted to reduce surface friction and enhance chain and sprocket longevity
Every JT sprocket goes through up to 25 production stages and 10 individual quality control checks before it is ready to leave the factory
