This is a replacement HPI 49T Steel Spur Gear Set, and is intended for use with the HPI Savage family of nitro vehicles. These steel gears are precision machined to HPI factory dimensions and hardened for the ultimate in strength, long life and maximum durability. To keep the weight down, these steel gears are thinner than the stock plastic spur gear, and the center steel section is removed and replaced with a light weight purple anodized aluminum inner Spur Gear Hub. These are an excellent upgrade for Savage owners, especially for high horsepower applications.
The convenient set includes a Steel Spur Gear, Spur Gear Hub, Slipper Clutch Pad, thread lock and installation hardware. Savage Racing Clutch bell not included.
NOTE: Due to the extreme strength of these gears standard clutch bells will wear out very quickly with these gears. It is necessary that Savage owners upgrade their Clutch Bell to one of the newly released Savage Racing Clutch Bells (#77103-77110).
