Quality Bobcat® Parts

Smaller sprockets for Bobcat® mini excavators are hardened in a one step procedure via electrical induction. This increases the depth of the hardness through the teeth while preventing breakage. Our aftermarket sprockets are hardened within millimeters of the original OEM sprocket which provides a great value for our customers overall. We recommend installing by hand to your manufacturers suggested torque specifics.
