Best reviews of ⌛ Mon Ster Shaft Sleeve Adapter With Step Key For Go-Kart Engines 🔔

The shaft sleeve adapter with step key for go-kart engines is a type of cylindrical spacer that allows you to increase the crankshaft diameter. By increasing the crankshaft diameter, this would allow using larger size wheels on smaller drive shafts. In addition, it would also allow larger pulley sizes not normally compatible with smaller diameter shafts.

Because different diameter crankshaft sizes use different keys and keyway slots, each of these adapter sets come with the correct size slot milled into the sleeve. If the standard key size differs according to shaft diameter, then the key will be stepped, fitting both shaft and sleeve.
