🔩 Hendrickson Intraax AAL Tandem Suspension
The Hendrickson Intraax AAL (Air/Air/Leaf) is a premium tandem axle air-ride suspension that combines air springs with a trailing-arm leaf spring for highway smoothness and payload capacity. It is specified by Peterbilt, Kenworth, and Freightliner as an alternative to the Hendrickson PRIMAAX for applications where load-sharing between tandem axles is critical. The Intraax's TrakFlo 4-point trailing arm geometry self-steers up to 3° in turns, reducing tyre wear on tandem axles by 25% compared with fixed-axle configurations.
