Kenworth has added a new tandem rear suspension for its Class 8 trucks. The proprietary  Kenworth AG400L, a disc brake-compatible suspension, is a 40,000-lb. highway system for the Kenworth T660, T800, T2000 and W900 models.

The four-bag suspension is suitable for over-the-road and P&D applications, Kenworth said, and is designed to provide a smooth ride through a trailing-arm design.

The OEM’s extensive family of proprietary suspensions also includes the AG130 front air ride suspension, and the AG210L, AG380, AG400, AG460 and AG690 rear suspensions.
