The HPI Heavy Duty Racing Clutch Bell 18T (HPI-77108) is a hardened, high-strength machined steel clutch bell built to handle the demands of HPI Savage monster trucks. Precision-drilled holes reduce rotating mass and help cool the clutch shoes, delivering consistent performance and responsive acceleration.

Key Features

  • High-strength machined steel construction, hardened for durability
  • 18-tooth bell with tooth count stamped for easy identification
  • Lightened design with machined holes for quicker acceleration and improved cooling
  • Compatible with stock Savage spur gears; mandatory upgrade when using HPI steel spur gears
  • Part of a range of tooth counts to fine-tune gear ratio for different terrain

Gearing Advice

  • More teeth on the clutch bell (or fewer on the spur gear) increase top speed with slightly reduced acceleration – ideal for smooth surfaces and longer straights.
  • Fewer teeth on the clutch bell (or more on the spur gear) improve acceleration and torque with slightly less top speed – ideal for rough terrain, steep hills or tight tracks.

Suggested Compatibility

  • HPI Savage monster trucks
  • Stock Savage spur gears
  • HPI steel spur gears (mandatory upgrade)

Notes

  • Requires HPI-B021 bearings.

The HPI Racing Clutch Bells for the Savage monster trucks are made from high strength machined steel and hardened for maximum durability to provide lasting performance in any driving conditions.

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. Each gear is stamped with the number of teeth for easy identification.

The Racing Clutch Bell is available in different teeth numbers, giving racers and bashers the choice to adjust the gear ratio to the terrain for optimum performance.

The more teeth on the clutch bell (or fewer the teeth on the spur gear) the more top speed with slightly reduced acceleration, ideal for smooth surfaces or longer straights. The fewer number of teeth on the clutch bell (or the higher number of teeth on the spur gear) better the acceleration and torque with slightly less top speed, ideal for rough terrain, steep hills or short tracks with tight corners.

Note: requires HPI-B021 Bearings
