Replacing OEM undercarriage parts with aftermarket undercarriage parts offers significant cost savings, and in 99.9% of cases, the parts are manufactured to be just as effective and reliable as the originals. One thing we recommend at FortisTracks, is to make sure that any parts your purchase — OEM and aftermarket — come with a warranty. Warranties on aftermarket heavy equipment parts will save you from the very small chance that an aftermarket part doesn’t work properly.

Before buying any undercarriage part, it’s crucial for you to check the manufacturer’s spec book to ensure that the aftermarket skid steer part, aftermarket excavator part, or any other aftermarket undercarriage part has the same dimensions as the OEM part. If the ratings and dimensions of the aftermarket undercarriage part are the same as the OEM part, you can use it with your heavy equipment.

If the equipment is properly maintained, aftermarket undercarriage parts from reliable providers are just as good as OEM parts — and come at a fraction of the cost. The resale value of heavy equipment will not be affected by installing aftermarket undercarriage parts. In fact, many times this shows used heavy equipment buyers that you took proper care of your machine and stuck to maintenance and replacement schedules.
