The proprietary Kenworth AG400L tandem rear suspension is now standard equipment on the OEM's T680 on-highway flagship truck.
The AG400L is rated at 40,000 pounds and is compatible with disc brakes. The four-bag suspension is designed to be a cost-effective solution for over-the-road and delivery applications. A trailer arm design can result in a smooth ride and the suspension is also easy to service, according to Kenworth.
“The Kenworth AG400L provides the T680 driver with a comfortable and smooth ride,” said Kurt Swihart, Kenworth marketing director. “The suspension is also virtually maintenance free with few moving parts, and there are no periodic adjustments or lubrication required.”
Kenworth’s family of proprietary suspensions also includes the Kenworth AG130 front air ride suspension, and the AG210, AG380, AG400, AG460 and AG690 rear suspensions.
