The National Seating HP air suspension is the best solution when you are seeking the best buffer from road and vehicle vibration. The HP was designed to simply excel in this reduction of transmissibility. The vibration your body experiences in operating vehicles for long periods of time can cause strain and fatigue or simply put discomfort. This discomfort can reduce your effectiveness and impact your bottom line.

In developing the HP we utilized our experience from our global seating operations, years of real world suspension production and testing information from seven competitor suspensions to ensure the results yielded a superior product. The chart below shows the summary test data of the transmissibility testing of those seven other suspensions. The shaded area shows the range of vibration where the body reacts most negatively. The HP suspension performance is shown, clearly delivering the best results in this testing. Built to be durable and maintainable to ensure maximum life, the HP is the right solution to help you stay on the road longer each day and for the many days ahead.

The HP air suspension is found on the Admiral (40049 & 40079), Commodore (40050), and High Performance (40019) all-makes seats.  Also National Seating OE seat part numbers with a "3" or "4" as the first digit, as these above utilize the HP air suspension.
