ATRO Engineered Systems has added a suspension kit to its product offering – Hendrickson HN Suspension Rebuild Kit.
“As is our custom, ATRO listens to customers’ requests regarding additions to our product line and strives to meet those needs,” said Jay Moore, ATRO product manager. “We are excited when we can streamline a solution by packaging a complete repair into a time-saving kit that gets the truck back on the road.”
The Hendrickson HN walking beam suspension features bar pin end bushing. The traditional center bushing is replaced by two (per side) large bolster springs. ATRO’s new KT50-25004 includes components to do one side of the truck (two bolster springs and an auxiliary load spring).
