Product Overview

The C81-1004 Genuine Kenworth Air Spring is a pneumatic suspension component used in Kenworth AG200 and AG400 40K suspension systems to support vehicle loads and control vertical axle movement under changing road conditions. Its multi-ribbed rubber bellows and steel bead plate construction form an expandable air chamber that responds to suspension compression and extension, helping absorb road impacts and maintain regulated ride height through controlled air pressure.

Product Features

The C81-1004 Air Spring provides pneumatic load support and controlled axle movement within Kenworth AG200 and AG400 40K suspension systems.

  • Supports vertical suspension movement by compressing and expanding the air chamber under changing axle loads
  • Uses multi-ribbed rubber bellows construction to accommodate repeated suspension compression and extension cycles
  • Incorporates circular steel bead plates that provide structural support at the air spring mounting surfaces
  • Maintains a specified 9.0-inch height profile for the designated suspension assembly configuration
  • Helps absorb road impacts and reduce vibration transferred from the axle into the chassis
  • Supports regulated suspension ride height through controlled air pressure during loaded and unloaded operation

Installation Notes
