Introduction

This manual provides information necessary for the installation and 
operation of the SAF-HOLLAND

®

 CBX69 trailer air suspension 

and slider system. Although the images throughout this manual 
depict the CBX69, there is no difference in fit or function 
between the models in the CB Series. 
 
The CBX69 suspension includes premium 5.75" diameter axles. 
For axle end and/or brake servicing information or component 
replacements, refer to Drum Brake Manual XL-TA10006OM-en-US, 
Disc Brake Manual XL-SA10059OM-en-US or contact Customer 
Service at 888-396-6501.

This suspension uses air drawn from the tractor air system to 
pressurize the air springs. The height control valve (HCV) regulates 
the air pressure required for varying loads while maintaining the 
design ride height. This suspension can provide a cushioned ride 
throughout the load range, from empty to fully loaded.

The suspension also provides excellent side-to-side and  
axle-to-axle loading which helps equalize and control braking.

Read this manual before using or servicing this product and  
keep it in a safe location for future reference. Updates to this 
manual, which are published as necessary, are available on 
the internet at www.safholland.us.

When replacement parts are required, SAF-HOLLAND
