The LS series combines the strength and flexibility of long lasting hydraulic hose with the extra protection of heat treated stainless steel braid. The exclusive live stem inner core technology utilizes a floating valve stem that is activated only when air is added or removed from the tire. Hose fits every time. Installation requires no special adjustments and provides increased protection against tire deflation should the valve extender be damaged. For inner duals only. Fits 1992 to current Ford model years with 16", 16-1/2", 19-1/2" and most 22-1/2" wheels. Does not fit Ford E-350. Refer to 92-8079. 2 per pack.
