Cat® Sprockets

Smaller Cat® sprockets for compact 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.

Rubbertrax suggests changing sprockets and rubber tracks together as they are designed to wear together over time. The sprockets do not come with the replacement bolts. You need nine bolts (12mm) to mount the sprocket.
