Upgrade your Caterpillar 303.5C through 303.5C-ECR series rubber tracks to the premium aftermarket rubbertracks from Rubbertrax and increase lifespan and performance from your undercarriage. Be sure to verify your exact Caterpillar model number by checking your serial plate.
Some parts are not interchangeable among every sub model so please check your serial plate to verify that your exact model is listed as a fit for the parts you need. Sometimes a C, CR, CCR, D, DCR can all take a different roller type for instance. A standard 303.5 model requires a different listing of parts in a separate category.
