SIS 2.0 & SIS2GO
Cat Service Information System
Cat Service Information System (SIS) is the electronic service tool that covers all information for Cat products from 1977 to today. From SIS, you can identify and add parts to a SIS shopping cart, then bring your cart over to Parts.cat.com when you are ready to order and check-out. Caterpillar has now released the new SIS 2.0, with enhanced search features, seamless navigation across parts, and a new look and feel that is mobile friendly.
