These Racing Clutch Bells from HPI Racing are made from high strength machined steel and hardened for maximum durability. These Clutch Bells can be used with the stock Savage Spur Gears, and they are a mandatory upgrade when using HPI Steel Spur Gears.

Machined holes help keep the weight down for quick acceleration, and the holes also help cool the clutch shoes for consistent performance. Stamped with the number of teeth for easy identification.
