Cat starters and alternators ensure your generator set starts fast and finishes strong, every day and in any environment. Built to best-in-class Caterpillar OEM specs, Cat starters and alternators optimize performance for the full generator set lifecycle. Count on them to start your Cat generator set in the most extreme conditions and keep it operating in the harshest climates — bitter cold to blazing heat — resulting in lower costs and higher productivity.
Ensure durability and reliability
Built to work hard and deliver reliable performance even in tough, bitter-cold conditions, Cat starters are designed specifically to handle the high current experienced during the cranking of cold engines, every time.
System of Excellence
Cat starters, alternators, and batteries comprise the most robust electrical system in the industry so your generator set can perform the best in every condition.
Built (Military) Tough
The most rigorous, documented testing and validation confirms that Cat starters and alternators are engineered to exceed even military standards — for keeping your generator set up-to-speed and on the job.
Legacy of Longevity
Designed as lifecycle (not maintenance) components, Cat starters and alternators are built to last the life of the generator set—with a warranty to back it up.
