HN® FR

Fire/Rescue Suspension 42-48K

HN Fire/Rescue

Available exclusively to the fire and rescue industry, the HN® FR suspension system utilizes a VariRate® spring system to provide the perfect balance of empty ride quality and loaded stability. Its diagonally mounted rubber bolster springs act in compression and sheer to deliver superior ride quality by dissipating road shock, while its extra wide spring centers and auxiliary springs provide outstanding stability under challenging conditions.
