Makes hard-to-reach inner dual valve stems easily accessible for proper tire inflation. A stabilizer bracket snaps into a hand hole to keep the extender centered for easy access. The LS series combines the strength and flexibility of a 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. 92-8080 does not fit Ford E-350; use 92-8079. For inner duals only. 2/pack.
