Overview
The HPI Racing Heavy Duty 15-Tooth Clutch Bell (1M) is a high-strength one-piece clutch bell machined from a single block of high-strength steel — significantly stronger than standard two-piece clutch bell designs. It's designed for the HPI Savage monster truck and is also a popular hop-up for the MT2 and Rush Evo platforms.
By eliminating the press-fit gear-to-bell joint of a two-piece design, this one-piece clutch bell delivers improved durability and consistent power transfer under the heavy loads of nitro monster truck driving.
