Applications
This kit services one wheel end on Hendrickson Intraax trailer air suspensions with 16-1/2″ brakes:
- Intraax AAT 230 / 250 / 300 (23,000–30,000 lb axle ratings)
- Intraax HXS series with the same 16.5″ brake spec
- Dry van, reefer, flatbed, tanker, and intermodal trailers using Intraax air ride
Each kit covers ONE wheel end. Order two kits to rebuild a single axle, or four kits to rebuild a tandem trailer. Do not mix this kit with 16.5″ Meritor TQ-series or trailer drum-brake repair kits — the camshaft journal and bracket geometry are Intraax-specific.
