The Precision 0.5 sprocket range (65.5T to 85.5T) is built for drivers who demand absolute control. With 0.5-tooth steps, you can fine-tune gear ratios without touching the front sprocket—perfect for extracting that last tenth or dialing in consistency on any layout.
This lineup helps teams adapt gearing with surgical precision, avoiding compromise when engine response or track configuration demands subtle tweaks. Ideal for serious racers chasing margins that matter.

Half Tooth FAQs
Quick answers about our 0.5 pitch sprockets
Does it actually have a half tooth?
No, the sprocket doesn’t have a literal half tooth. Instead, it's a change in the circumference and rolling diameter, allowing for a finer gear ratio adjustment without needing to swap the front sprocket. It provides half the effect of a full-tooth change.
Will it fit my current 219H kart chain (Precision, DID, RK, etc.)?
Yes, all Precision 0.5 pitch sprockets are fully compatible with standard 219H kart chains, including those from DID, RK, and others. No need to change your chain or adjust tension beyond normal setup.
When should I use a 0.5 sprocket?
0.5 sprockets are perfect when you're dialling in lap times and need that mid-point gear ratio between two full teeth. They’re ideal on tracks where a full-tooth change is too much or too little, giving you that final edge in tuning.
