Cat® Retrofits allow new or updated parts to be fitted to older Cat machines and engines. 

Retrofitting your equipment means you can add features that were available, but not purchased, when you procured your Cat product; and add features introduced on newer equipment that were not available when you purchased, rented or leased your Cat product.

Retrofits are a key component of Caterpillar’s longstanding and ongoing commitment in research and development, to extend product lifecycles of existing Cat machines and engines. As a Cat product owner you stand to benefit from of this research and development by taking advantage of our extensive retrofit product and service offerings.

When to retrofit?

  • You want a new machine but your operating budget does not allow it
