T660 Class 8

Kenworth T660 — Class 8 Evolution of a Legend

The Kenworth T660 is a Class 8 conventional truck designed as the replacement for the iconic T600, blending aerodynamic innovation with driver-focused enhancements. While introducing a sharper, more modern exterior, the T660 retained the proven Aerocab cab and sleeper structure from the T600, offering familiarity with improved performance and styling.

Sleeper Options:

• 38"

• 62"

• 72"

• 86"

This variety makes the T660 a versatile long-haul solution for fleets and owner-operators alike.

Upgrade Your Seat — Enhance Your Drive

Whether you’re driving cross-country or day-to-day, a premium aftermarket seat can drastically improve your comfort, posture, and focus. The T660 accepts a wide range of aftermarket suspension seats.

You don’t need the wide-body adapter plates required for 2.1m cabs (like the Peterbilt 579 or Kenworth T680).

Classic comfort meets modern support — get the seat your T660 deserves.
