Atro Engineered Systems has unveiled a Hendrickson HN Suspension Rebuild Kit.
The Hendrickson HN walking beam suspension features a bar pin end bushing, and the traditional center bushing is replaced by two large bolster springs per side. ATRO’s new KT50-25004 includes components to do one side of the truck (two bolster springs and an auxiliary load spring).
Atro offers kits for heavy-haul suspensions including the Hendrickson Haulmaax, Kenworth AG 200/400, and Mack SS 34-44 Series and SW/ST34 Series.
The proprietary polyurethane materials used in the kits also resist dynamic compression set, and are chemically resistant to contaminants, Atro says.
