Automann Phoenix Rolling Lobe Air Spring - Hendrickson Intraax 23K Vantraax 46K - Firestone 9626 S-23720 AB1DK20J-9626

Put your trailer back on its ride height with this Automann Phoenix Rolling Lobe Air Spring distributed by FleetPro Parts & Tires. It carries the load and maintains ride height on Hendrickson Intraax AAL/AANL 23K and Vantraax HKARL 46K trailer air suspensions, and it is built as a straight aftermarket answer to the Firestone 9626. A cracked, chafed or leaking air bag drops the deck, bleeds air all shift, beats up the freight and finishes off the shock absorbers right behind it. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, trailer repair shops, and owner-operators nationwide.

23K and 46K Ride Height: The Automann Phoenix Air Spring Advantage

The geometry is what makes this bag a drop-in. It runs a 13in design height, collapses to 7.3in, and measures 11.7in at maximum diameter on a durable plastic base, at 13.96 lbs — the dimensions the Intraax AAL/AANL 23K and Vantraax HKARL 46K suspensions are built around. Rolling lobe construction lets the bellows roll along the piston instead of stretching, which is what keeps the spring rate soft and consistent whether the trailer is loaded to the roof or running home empty.

The plastic base resists the corrosion that eats steel bases from underneath a salted trailer, and the rubber compound is built for road salt, spilled lubricants, freezing temperatures and the highway debris a trailer axle lives in. Support the axle before you unbolt the old bag, and inspect the mounts and shock absorbers while you are under there — a dead shock will destroy a brand new bellows.
