New undercarriage parts and rubber tracks are sold individually but we suggest replacing all of your worn parts at the same time.
These are the aftermarket bottom roller for the following mini excavator models:
The Caterpillar® 302.5 takes six track rollers, but the 303.5 and 303CR require eight track rollers. These Caterpillar® track rollers do not come with the 10mm bolts required for installation.
This is a single flange roller that is 4 3/4 inches in diameter when new.
We offer same-day shipping at no extra charge.
