Caterpillar Parts Store

Our parts are OEM-equivalent aftermarket replacements, engineered and manufactured to match Caterpillar's original specifications for fit, form, and function. They are not branded Caterpillar parts but are designed as direct-fit alternatives, offering comparable performance and durability at competitive pricing.

We support a wide range of Caterpillar equipment including excavators, wheel loaders, bulldozers, mining trucks (777, 785, 794 series), Challenger tractors, generator sets, and industrial engines like the 3500 and 3126 series. Parts are cataloged by model and application for accurate fitment.

Pricing varies significantly by part type and application. AC condensers start around $84, while radiator cores, oil coolers, and aftercoolers typically range from $1,300 to $25,000+ depending on size and equipment. Complete cooling packages for large generator sets can exceed $50,000.

Yes, we offer complete cooling packages combining radiators, oil coolers, and charge air coolers into single OEM-compatible units for Caterpillar and other equipment brands. These packages simplify installation and are available for construction, drilling, and industrial engine applications.

You can search our online catalog by SKU, equipment model, or product type such as radiator, oil cooler, or charge air cooler. Each listing specifies compatible Caterpillar models and equipment types to help you confirm fitment before purchasing.

A radiator core is the internal cooling element—tubes and fins—that dissipates heat, while a complete radiator includes the core plus top and bottom tanks, mounting brackets, and fittings. Cores are often used for rebuilds, while complete radiators are full replacement units.
