The Fast and Easy Way to Level a Trailer
One-Touch Operation
No more cranking your arm off to raise or lower your trailer. With one simple push of a button the power stroke plus system raises or lowers your trailer 18 inches in just 30 seconds. And the manual crank override gives you an additional 6 inches of travel for 24in. total height.
Easy Plug and Go System
No hard wiring is required. Simply unplug your trailer connector, plug in the trailer jack to your vehicle's prewired 7-way connector, and push the button. The jack runs off your vehicle's 12V battery … it's as simple as that!
At-A-Glance Leveling
No need for laying your torpedo level across your trailer in an attempt to get an accurate reading. This jack features a built-in leveling gauge that lets you watch your progress as you raise or lower the jack. LED lights are built into both sides of the jack to make viewing what you're doing easy, even at night.
Anti-Divot Foot Adds Stability
An oversized 5 1/4in. dia. footpad provides the added surface area you need to get a solid footing on any terrain without sinking or taking a big divot out of the ground. The solid zinc-plated foot is also adjustable on detachable 1 1/2in. centers for the most stable positioning.
Fits Any A-Frame
This versatile jack is predrilled for compatibility with any trailer featuring an A-frame coupler. No guessing. If it's an A-frame, this jack will fit.
Toughness and Dependability in the Field
Never Leaves You Stranded
You never have to worry about this jack not doing its job. With a weather-sealed switch to keep the electrical drive running in any conditions, rain or shine, to the manual crank override that allows you to drop or raise the jack by hand, this jack is ready for any situation.
The Guts to Perform
This jack is built tough, all the way through. The hardened steel gears stand up to the test of time to prevent stripping and slipping for consistently smooth operation.
Measures Up to Your Needs
With 3,500 lbs. lifting capacity and 5,000 lbs. of breakaway capacity, this lightweight (only 19 lbs.) jack is up to the task. The jack measures 27in. from the mounting ring to the top of the motor and has a 26 1/2in. retracted height.

is the bolt pattern universal

GraftonRoadRacer· 15 years ago
There is a triangular (3 bolt) pattern which appears to me to be universal. Fit my trailer tongue perfectly.
Helpful?

CampingEnthusiast· 16 years ago
Yes. The A or 3 hole triangle configuration was the same as on my camper, but I had to make my Jack's housing cavity wider on my camper. However, my camper's jack housing was a jerry-rig job, not to standard width like should be on your camper. I had to shave off about a 1/8 of metal all around the housing cavity in order for the jack to go into. Took about an hour.

DandL82TN· 16 years ago
I looked at several campers and this electric jack has the standard triangle pattern where the three bolts attach. The toggle switch (for up and down operation) will be towards the front and the light switch will be in the back. But to answer you question, yes, it seems to be the standard triangle pattern.

the 3 bolt triangle is the same as a standard trailer jack. unbolt your old one and bolt this one right up. I did add larger thicker washers to mine to be safe since I have a heavy load most times.

Pickup tailgates
Can the tailgate on a pickup truck be opened without hitting jack or touching the jack or do you have to have a extra long hitch?
-
Pixhog· 8 years ago
My 2016 F150 4x4 was in danger of hitting my trailer jack. I had this electric jack still in the box from 2012. I took it to a welding shop and asked a guy to install it but move it back a little. My tail gate now clears the jack. I would have had to move it a little with either one.
Now my problem is getting power to the electric jack since my truck didn’t come with that connector pin powered up. As described in the instructions, this can be a fairly common problem.

I noticed it looked like it had a leveling bubble on it, does it have to be level?
-
JeffStL· 14 years ago
No, just handy if using on a camper to aid in set up.
Helpful?
-
jjkd· 14 years ago
No, the jack itself doesn't need to be level, the bubble is a convenience for you when using the jack to level your trailer without needing a separate level. How accurate it may be will be up to the exact build of your trailer, so you need to compare the indication of this level against your other level(s) before relying only on the jack's level.

It has a 7 pin adapter installed so just plug it into your outlet on your vehicle

GraftonRoadRacer· 15 years ago
The jack comes wired with a 7-prong RV plug that plugs into the standard 7-prong RV recepticle that is found on most pickups and larger SUVs. If your recepticle is wired correctly, it should work fine; otherwise you'll have a little wiring to do (you'll need to get a heavy, fused "hot wire" to back of your truck). I was expecting to wire it when I ordered the jack, but was very pleased to see the plug already to go. What I like about it, is that you can use trailer and this jack with ANY truck or SUV with a 7-prong RV recepticle.

ProductExpert31· 13 years ago
A 20A breaker will allow 50A of current for 10 seconds. That would give any "power boost" required. The amp draw under load is 50 amp and no load draw is 15 amp.
