The Washington State-based manufacturer of tractor-trailers (a sibling of Peterbilt Trucks) has the claim of having one of the most reliable semi-trucks in constant production for over 50 years—the iconic Kenworth W900. In 2019 Kenworth added the W990, building on the proven performance of its predecessor which promises a long production run for many more decades as it is a staple of American and worldwide freight routes.

With its high-performance diesel engine and a variety of other models—including the T-line, K-line, and C-lines of medium-duty trucks—Kenworth continues to grow its market thanks to its proven reliability. Kenworth is also known for manufacturing mass transportation vehicles like buses—namely the K, W, T and C model series—and later on it made an even bigger impact as a manufacturer of “yellow” school buses, many of which are still in use across America.

On-Site Fleet Services has extensive experience working on Kenworth models, ensuring their owners remain at the forefront of the industry—keeping their semi-trucks on the road and always operational. Our goal has always been to serve as a great partner to our customers, whose preventive and periodic maintenance and tractor-trailer repairs can ensure a long life, generating revenue as a reliable commercial truck.
