Aftermarket Replacement Parts for Caterpillar Equipment

Parts Online carries aftermarket replacement parts for Caterpillar construction equipment, including skid steers, excavators, wheel loaders, backhoe loaders, dozers, graders, and telehandlers. Our catalog covers commonly replaced maintenance, wear, and service parts such as cab glass, ignition keys, mirrors, wiper parts, fluid caps, breathers, and air filters. Each product page lists the OEM part number it replaces so you can verify fitment before ordering.

We stock glass for a wide range of CAT equipment including door glass, window glass, side glass, and rear glass for skid steers, excavators, wheel loaders, and dozers. We also carry keys, mirrors, and wiper components for cab maintenance. If you are unsure which part fits your machine, contact our team with your model and serial number and we will help verify compatibility.

Aftermarket vs OEM CAT Parts

Aftermarket parts are manufactured by third-party suppliers to match the form, fit, and function of the original Caterpillar part. They replace the same OEM part number and are designed to the same dimensions and material specifications. The main difference is price. Aftermarket parts typically cost significantly less than ordering the same part through a CAT dealer. For wear items like cab glass, keys, mirrors, and wipers, aftermarket replacements perform identically to the OEM original.

Parts Online matches every product to its OEM part number so you can cross-reference what you need. If your CAT dealer quoted you a part number, you can search that number on our site to find the aftermarket equivalent. We do not sell parts for proprietary electronic control systems or software-dependent components. Our catalog focuses on mechanical, wear, and maintenance parts where aftermarket alternatives are well-established and reliable.
