For severe conditions encountered under some forms of Phazer-class racing, competitors may experience excessive drive sprocket wear. If this occurs, you could install aftermarket introvert/extrovert drive sprockets available from Wahl Brothers Racing (phone number 218-782-2295).

The Wahl Brothers 9 tooth drive sprocket part number is 02-579 and the price is $81.85 each. These parts should improve your drive sprocket durability under severe race conditions.

If you do choose to compete with this drive sprocket change, confirm if the sprockets are allowed under Phazer stock-class rules with your race organization.
