Upgrade Your Seat — Because Comfort Matters
The T680 delivers industry-leading safety, efficiency, and driver satisfaction — so why not upgrade your seat to match? Choose an aftermarket suspension seat that offers the best in modern technology and ergonomic design, tailored to your body type and comfort preferences.
If your T680 came equipped with a Gramag seat (found in trucks from 2013 onward), installation of an aftermarket seat will require an adapter plate with integrated tethers for proper fit and safety compliance.
Drive farther. Ride better. Sit in comfort.
