Available now from HPI Racing is our machined 17 Tooth Heavy Duty Clutch Bell for the Savage monster truck! Because our Heavy Duty Clutch Bells are machined from a single piece of high-strength steel, they are much stronger than standard two-piece clutchbells. The stock Savage truck includes a 14 tooth clutchbell - for extra top speed we now offer 15, 16, 17 and 18 tooth clutch bells! Also available is a 13 tooth clutchbell for extra torque and acceleration. Requires the 49 tooth Savage spur gear (#76939), recommended for on-road driving only.Each clutch bell is clearly marked and packaged individually with a Savage monster truck gearing chart.
