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

Hi, I see the HPI Savage XL 4.6 is listed in the specification section for this clutch bell; does that mean it would also fit the Trophy Truggy 4.6? Are clutch bells for 1/8th scale generally universal fit? Thanks,

James / 18th February 2025

Yes they will fit and yes they are fairly universal.
