Kenworth AG400L Tandem Rear Suspension Now Standard on Kenworth T680

Kenworth tandem rear suspension

The proprietary Kenworth AG400L tandem rear suspension is now standard equipment for the Kenworth T680 on-highway flagship.

 

The disc brakes-compatible Kenworth AG400L is rated at 40,000 pounds. The cost-effective, four-bag suspension is especially well-suited for over the road and pickup and delivery applications. The AG400L provides a smooth ride through a proven trailing arm design. The AG400L series also is easy to service.

 

“The Kenworth AG400L provides the T680 driver with a comfortable and smooth ride. The suspension is also virtually maintenance free with few moving parts, and there are no periodic adjustments or lubrication required. The AG400L offers excellent value for our customers,” said Kurt Swihart, Kenworth marketing director.

 

Kenworth’s extensive family of proprietary suspensions also includes the Kenworth AG130 front air ride suspension, and the AG210, AG380, AG400, AG460 and AG690 rear suspensions.
