Smoker Performance Carbon Fiber Sprocket GuardA sprocket guard is a round shield that sits behind your kart's rear sprocket to stop rocks, grass and fingers from hitting the spinning chain and teeth. This one is made from real woven carbon fiber so it's super strong yet weighs almost nothing. Racers choose the Smoker Performance version because the precision lightening holes and split design keep rotating mass low while giving full coverage.
