Benefits of Upgrades and Retrofit Kits
Cat® Retrofits allow new or updated parts to be fitted to older Cat generator sets. Retrofitting your power assets lets you add features not originally purchased or available when the asset was purchased.
Retrofits are an effective and economical method to extend the lifecycles of existing Cat gensets. They keep your genset compliant and up to date with current features and technologies.
