NOTES: * Not supplied by Hendrickson, used for reference only. Hendrickson is not responsible for components supplied by the vehicle manufacturer. For assistance with maintenance and rebuild instructions on these components see vehicle manufacturer. ** Item included in kit / assembly only, part not sold separately. *** Axle spring seats come assembled with the axle beam and are not serviceable. **** Effective January 2019, vehicles equipped with Hendrickson STEERTEK NXT/ STEERTEK axle will be installed with a left hand composite bearing and a right hand roller bearing configuration to replace the previous roller / roller bearing configuration for production and aftermarket. ***** The recommendation of the vehicle manufacturer is that dual height control valves are only to be installed on the front suspension when the rear suspension is equipped with a single height control valve system.This arrangement is best suited to keep the vehicle level versus having dual height control systems on both the front and rear suspensions. ****** No longer available for service, see Replacement Guide on Page 134.
