1999 CAT 3126 Engine For Sale
About This 1999 CAT 3126 Engine
The Caterpillar 3126 is a 7.2-liter inline-six turbodiesel that became one of the most common medium-duty engines on the road — you'll find it in Freightliner FL-series, International, and GMC/Chevy Topkick and Kodiak trucks, school and shuttle buses, box trucks, and RVs. Its HEUI fuel system and broad parts availability make it a practical engine to keep running, which is why used 3126s stay in demand for repowers and rebuilds. This 1999 3126 is sought after by owners maintaining older medium-duty trucks and equipment. Every 3126 we sell is inspected and tested before shipping, identified by stock number (218771), and includes warranty coverage. We ship nationwide with freight quoted to your destination. Have your truck's year, make, model, and application ready and our parts team will confirm fitment before you order — call (800) 696-5459.
