Our factory-trained Cat experts are knowledgeable about the company’s entire line of construction equipment and other machines. Many Cat parts can be reconditioned or restored — if there’s a viable alternative to buying new parts that will save you time or money, our team will let you know. Whether you need something as simple as an oil filter or a major component assembly, contact Fabick CAT for all heavy equipment parts in St. Louis and throughout MO, WI, upper MI and Southern IL.


To support a broad range of clients and their equipment, we offer several options when shopping for construction equipment parts in WI and beyond:

  • New parts: New OEM parts are the best choice for all recent Cat construction equipment. Order online or in-person — it’s easy and convenient to get the items you need when you shop with Fabick CAT. As the exclusive representative of Cat equipment in our region, we have access to a nationwide dealer network and can quickly track down even hard-to-find or backordered items.
  • Used parts: Buying used is a great alternative for older machines or for any repair where it is necessary to replace a complete component assembly such as an engine or transmission. The major components of all Cat equipment are capable of being reconditioned to like-new conditions — with the right combination of new and used parts from Fabick CAT, even a complex repair can be made straightforward.
  • Nexus and classic parts: When OEM isn’t an option, Fabick CAT can source aftermarket parts for older machines or for equipment by allied brands. Make us your first choice for replacement parts for all construction machines, including those by John Deere, Case, Hitachi and more.

Whatever an upcoming repair needs, we’ll match you with the best solution for your budget. To our clients, Fabick CAT parts representatives are more than just sales associates — they’re trusted advisors who can help you make smart choices to keep your heavy equipment running at its best for years to come.
