Getting the trailer away from the cab

Keeping the ball ahead of the rear axle for balance & steering weight

Watch the neck gussets for clearance on the truck bedrail

Save your trucks rear window with a wide nose

Room for propane tanks and a tailgate

Moving the trailer back

90 degrees &  inches to spare on wide nose

This is at 90 degrees against the cab further forward than you need.

You also have more room between the tailgate and trailer.

Simple to attach.

Just slides up the gooseneck tube.

 Spring loaded coupler can be latched inside & outside the bed

You know I like extreme tests!

Who says I don’t take notes!

Quick spring loaded coupler

Built like my dad made it

With newer hydro-formed boxed frame trucks, you may not be able to mount your ball in the truck bed where it does you the most good. This well built coupler from Popup Industries is a fast and safe solution to mounting the ball 2 to 4 inches ahead of your rear axle. I like the ball 4 to 5″ to allow all your truck springs, axles and bearings to be working for you. Having the proper “steering weight” on your front axle gives you better control. Your want your trailer level also, so the trailer can use all of it’s springs, axles and bearings as well as have the maximum trailer brake available to you.

“I installed the SB1 extender on a Featherlite 4 horse trailer last fall and it has worked great.  I can tell no difference at all in the way the trailer pulls or how it handles. We have a lot more confidence in maneuvering the trailer in tight spots, especially those 90 degree turns through narrow gates. I pull every weekend to a bird dog field trial some where on the east coast.  It’s a great product and a good idea. Jim J.”

You want to be able to distribute the trailer weight over all the axles of your truck and trailer. In the RV world there are several hitch companies that make “sliding mini-fifth wheel hitches.” Ever see a sliding adjustable ball? This gooseneck coupler tube extension is built like a tank! It comes with a spring loaded coupler, so you can pull the included cable to latch and unlatch your trailer without climbing in the bed. Yes I said ‘without climbing into the bed.” I have talked to trailer manufactures about using this new coupler extension and was told that they “didn’t have a problem with it.” order here.

Another way to hitch a short bed. This will prevent hitting the cab of the truck with the trailer when jack-knifing.  But how much would a welding shop charge to make an extension hitch and would they test it and stand behind it? What if it’s welded at the wrong height?

More Trailer Swing, Easier Hook-Up.

Everyone who tows a gooseneck trailer needs more clearance between the truck and trailer. You either need more trailer swing for maneuvering, or you need more room at the tailgate for hooking up. Well, PopUp has a simple solution to this predicament. The new PopUp Short Bed Extended Coupler provides nine inches more clearance between the truck cab and the trailer nose, and between the truck tailgate and the trailer bulkhead – giving you more trailer swing and more room for hook-up. To make the towing experience better yet, this extended coupler latches and unlatches remotely. 3 3/4 inches from ball to top gusset against the trailer neck tube. That’s how much clearance you’ll have with the SB1 all the way up the trailer tube. The new PopUp Short Bed Extended Coupler fits standard round trailer tubes, square tubes and installs in about thirty minutes.
