WHY USE A KING PIN JACK?
All fifth wheel trailers have front landing gear which support the front of the trailer. The landing gear is designed to lower, raise, and support the front of the trailer. Most landing gear has a certain amount of play between its telescopic landing gear leg and its housing. The amount of side to side sway will vary with different manufacturers’ landing gear.
To eliminate the annoying side to side movement in the front of your fifth wheel trailer, you need a fifth wheel king pin jack.
There are two types of these jacks:
1.) BAL’s Two-Leg Jacking Design
2.) A Tripod Non-Jacking Design
WHY USE A BAL KING PIN JACK?
There are numerous advantages with BAL’s patented two leg king pin jack versus the various tripod models being sold.
First, BAL’s jack design is much lighter than the tripod design. This means easier handling and less weight to lift.
Second, the BAL king pin is much more streamlined than the bulky tripod design. This means that the BAL king pin jack requires much less storage space than a tripod model.
Third, the BAL king pin jack is easier to set up and use. For the BAL king pin jack, you simply position the top of both legs against the trailer’s king pin, attach a chain and then turn the jack screw for 10-20 seconds until the trailer is stable. With the tripod design, it must be opened up and positioned under the king pin. The trailer’s landing gear must then be lowered down onto the tripod jack until the trailer is stable. If the trailer is not level because lowering the front end of the trailer will raise the rear end of the trailer, you must re-level the trailer. This means adjusting the tripod jack so that it will “stretch out” at a different point, hopefully, the point at which the trailer is level. This trial and error method is not required with the BAL design.
In summary, the BAL king pin jack is lighter, more streamlined and easier to use than tripod models.
