The Ranger model RFJ-4000AL is a lightweight aluminum racing jack that weighs in at 39 lbs. But don't be fooled: it packs a mean punch and is as durable as any steel jack， even though it weighs much less and takes very little effort to pump. Not to mention， the speed at which you can get any vehicle to the maximum rise is incredible. 3 pumps will raise the jack. 4 pumps will raise it to its maximum height. That's about as easy as it gets for a floor jack. With a built-in safety overload valve， you're protected from overloading the hydraulics as you jack， so you never have to see your vehicle come crashing down unexpectedly.
