HPI Heavy Duty Racing Clutch Bell - 13T

The HPI Heavy Duty Racing Clutch Bell 13T (HPI-77103) is a durable upgrade designed for tough running. Made from high-strength machined steel and hardened for longevity, it delivers consistent performance across varied driving conditions. Machined lightening holes help reduce rotating mass for sharper acceleration and promote airflow to cool the clutch shoes. Each bell is clearly stamped with its 13T tooth count for easy identification.

Key Features

• High-strength machined steel construction, hardened for maximum durability
• Lightened with machined holes for quicker acceleration and improved clutch shoe cooling
• 13-tooth clutch bell with stamped tooth count for easy ID
• Usable with stock Savage spur gears; a mandatory upgrade when running HPI Steel Spur Gears
• Engineered for lasting performance in a wide range of conditions

Gearing Guidance

• More teeth on the clutch bell (or fewer on the spur): higher top speed with slightly reduced acceleration – suited to smooth surfaces and longer straights
• Fewer teeth on the clutch bell (or more on the spur): stronger acceleration and torque with slightly less top speed – ideal for rough terrain, hills or tight tracks

Suggested Compatibility

HPI Savage monster trucks (suggested compatibility).

Notes

Requires HPI-B021 bearings.
