Today we're going to be taking a look at the Bulldog Powered Drive Trailer Jack designed for use on A-frame trailers, it offers a drop leg, 14" of lift, and a 4,000 pound weight capacity, part number in black is BD500199. This is also available in white as part number BD500200. With both our jack extended fully and our drop leg extended fully we're going to have a bracket height, or a height to the piece of steel we mounted the jack to of about 32". If we reduce the lift that we get from our drop log which is 8" that'll bring us down to about 24". With our drop leg fully extended, at our lowest position we're going to have about 18" to the top of our bracket, so if we we're to reduce the 8" the drop leg adds we'll be all the way down to 10". The Bulldog jack's a really nice clean looking jack.
Looks a little different than a lot of them that you see out there. Our top cover is fully sealed, we've got our switches located right here on the front, access hole if we ever need to get into the emergency lift section there, and also a fully adjustable level here that allows us to level out our trailer. Then adjust that so it's level, and we'll know we're always going to have a perfect match. The housing comes down and over, it's got a full lip all the way around the bottom that overhangs that lower section so it's not just putting two pieces of plastic together, we've actually got a nice overlap that's happening to give us some additional weather resistance. We've got our retract and our extend right here, easy to get to, toggle style switch. We've also got the button right here that's going to turn on not only the light that comes up here to the front for where we're going to be connecting to the vehicle but it also offers two almost spotlight style LEDs on the side with a really wide angle that'll come out and help us with those weight distribution set ups and things like that.
Also, something that's nice as you can see there, when we get to full retraction, see we've got that stop point, or full extension, there's going to be built in stop that are going to prevent us from over revving or over cranking and doing any kind of damage to our motor, so it's a really nice built in fail safe. Our main tube here is going to have full corrosion resistance put on it and even our inner tube, our drop leg, and plunger kit are all going to have corrosion resistant properties built in so it'll make it a good long lasting product. The plunger kit is pretty awesome really. Let me retract the jack just a little bit to give us some free play here. Whenever we get where we're going and we're ready to drop it, pull that, allow it to slide down, perfect. Once we hook up the trailer, it's time to leave, we're not going to have to worry about kneeling down, doing a pin and clip situation, trying to get it put back in, we just pull, raise it, and as soon as that slides back in we know we're in our highest position ready to head down the road.
Another great feature that way have, a lot of trailers nowadays have the side load aspect just like this one, you take a panel off the side, you can drive your four wheeler or whatever it is right up on the trailer. That puts a lot of side to side strain on your trailers as you can imagine, so what they've incorporated here with this Bulldog is from where our drop leg meets our inner tube, even at full extension we've still got about 6" of overlap between those two giving us that great side to side stability, same thing can be said here for our upper tube and our inner tube, where they meet we've got good overlap so we get plenty of support side to side for those side loading applications. The jack can not only be mounted in a forward facing position as you see it here but also in a sideways configuration which we'll give you a few more details on here in a minute. Now let's go over a couple of measurements and see exactly what room we're going to need. From the center of our outer tube to the outermost edge of our jack here on the back it's about 3 1/2" then from the center of our tube to the outermost edge of our jack if we we're to use it in a sideways configuration is going to be about 2 1/4". From our top plate or our bracket where we mount the jack to to the very top of our jack, we're looking about 21". We just want to make sure that we keep enough room over top of that to accommodate the head of the jack.
Once we have our trailer sitting nice and level, our spring loaded level here on the top's going to allow us to adjust it to where it's going to line up perfectly, sometimes our brackets can be a little bit off there, so all we have to is make our adjustment here, get that dialed in so it's centered. While it's not as important on an open trailer and things we've got like this, and with every situation you're going to be using it in, we'll be able to get that perfectly flat and level. If you want it to be set on a different angle, you're not stuck having your bubble halfway off, you can set the angle you want your trailer to sit at and adjust your levels so that when you hit that mark you'll know and the bubble will be nice and centered right there on top. We've also got the rubber cap here on top, if we get in the situation where we lose battery power we can pull that right out, use the attached handle, slide it in, you want to rotate it til it clicks in just like that and then you've got full control here just like you would with a manual jack. We're never going to run into a situation where we're not going to be able to hook our trailer up or unhook our trailer, even if our batteries have gone bad and we don't have any option there. Whenever we get done, we'll put that nice rubber plug, see it's nice, soft, and malleable, but it's going to seal up that hole really well, right on top, and that's going to protect our internal components and keep that nice and water resistant. The installation's going to be pretty straightforward, it's a nice easy setup to do, it's going to need the 2 1/4" diameter main hole for the 2 1/4" jack tube to come down through. The leg coming out itself, our inside tube, that's going to be 2" so all your 2" accessories are going to work great for that. As far as installation goes, we'll pull the pin and clip located here at the bottom, we're going to take that drop leg all the way out, with that set aside we're just going to slide our jack right down into the hole location and then kind of rotate it around, the front of it should be facing forward so our holes line up. In our conventional setup we just have our jacks right out the front here, but something that's nice, if we're very limited on access, if the front of our trailer comes up really close to where this is, we can rotate that 90 degrees and our holes are going to line up once again giving us the option to mount it this way, saving us a lot of space there. Our jack's going to come with a basic set of hardware to help with our installation. In our case today, our holes are threaded, designed for use with 3/8 bolts which are included so we're going to be able to thread right down into those. If you've got pass through holes or if your 3/8 bolt passes down through then they also include nuts. In addition to that we've got star washers and lock washers and the only thing we're going to add are some just basic flat 3/8 washers, just to help cover up those oblong holes on the top so our lock washer will get a good bite. We're going to bring our drop leg around the underside of our A-frame here and then as we lower our jack, we'll lower it right down onto that. We'll then take one of the star washers and place it under each of the three hole locations, this is going to go through the mounting bracket on our jack and the top of our trailer. Then we'll take one of our 3/8 bolts with the flat washer, lock washer, and bolt, and place it right down in and just get our thread started there. With everything started, let's snug them down. Now we can grab our torque wrench and torque it down to the specifications we'll find in the instructions. Wiring's a nice easy process, we've just got a single power wire that we need to get to our 12 volt power source on our trailer. This trailer works with a junction box, we've got a 12 volt power wire that's designed to come up, connect into the trailer, just like that. We're going to be using heat shrink butt connectors today, those are available on our website, if you don't already have them at home go ahead and pick a few up. We just want to trim off the end of our power wire, whether this goes into our battery, whether it runs through the vehicle, or wherever your 12 volt power source is on your trailer, that's where you'll want to pick it up. Add a butt connector there, crimp that down, the end of our jack wire's already stripped off there, we're going to just clean it up though. That's going to go right into the other end here. Give it a good pull, make sure that's nice and solid, then we can use a heat gun, or a lighter, or a little mini torch, or whatever we've got handy there. Apply some heat here to our connector and allow those ends to shrink down. We've got some extra wire here which is great, if we ever need to make any repairs or make any changes we'll have some extra there. Let's go ahead and just get it tidied up, like to bring it straight down the jack tube and then put one of our zip ties around the bottom here, seems to give us a good anchor point down here so we're not worried about hanging up on anything while we're using our trailer in our everyday operations. Then for the excess, just get that neatly bundled here and we're going to tuck this up against the frame rail of the trailer and just keep it up above the frame rail that way we won't have any issues with it hanging up. Just keep it up out of the way so that it doesn't get hung up on anything. For installing our plunger kit we want to remove our drop leg. We'll pull that pin out as far as it'll go, as you can see that pin's going to have a little slide through on it. Got a little tab there and then the notch on the backside of the jack tube is what that's actually going to slide right up onto. We pull our pin all the way out, slide it up on there, and then our pin's going to go right through the hole that normally we would put the standard style pin in. With that in the proper position there, we'll go ahead and tighten down the nut that's here on the backside, this is going to be a 15. Then this allows us a very quick and easy way to operate our drop leg. Slide that back in, pull out the pin, you can see at each of its notches it's going to catch instantly. While it might take you just a second to get it installed, it's something that really comes in handy and saves us a lot of time. Once we pull up to our location where we need to unhook our trailer, drop that down to whatever height we require, and we don't have to worry about always putting this pin in and out, maybe losing it somewhere and then our drop leg's ineffective, so just a great way to have that fully functional and ready when we need it. That'll complete today's look at the Bulldog Powered Drive Trailer Jack, with 14" of lift and a 4,000 pound capacity, it's part number is BD500199.

This electric A-frame jack offers 22" of total lift. The drop leg has a spring-loaded pull pin for quick release. 3 LED lights allow easy setup at night. Built-in level included. Surfaces are sealed, maintenance-free, and corrosion resistant.I purchase this item to replace a 12 year old power jack. I’m spoiled and I’ll never go back to a manual jack. The jack feels and looks like a high-quality unit. All hardware was individual packaged. Installation went smoothly following the excellent directions. I’ve run the jack up and down a couple of times and it functions smoothly and quietly. The drop-leg is an excellent design. I look forward to many years of service from this jack. 514321

I installed this electric jack on my 3-horse bumper pull trailer. I'm using power straight from the truck's RV 7 wire hook-up. I, along with my family are so glad I installed this every time we hook up to the trailer. The adjustable leg is also an added benefit. I also purchased the termination box and this allowed for a superior installation by putting all the terminations in a water proof box versus open wire joints. Thanks etrailer for your support and your quality products. 335219
shorty s - 01/25/2018I bought an electric trailer jack. The price was fair, shipping was fast, and item was exactly as described. Great service! 666380
I am extremely pleased with everything about the purchase. The jack was described very accurately, I had a question before delivery about the fit on my R-Pod which was answered very thoroughly and the jack arrived on time. The installation was quick and easy. The jack operates very smoothly. The features of the LEDs, the quick pull pin for the drop foot and the bubble level are perfect for my application. 493559

Trevor J - 01/08/2019I have a 2007 14' V-noise extra wide and tall trailer, and the jack was needing to be replaced. I figured it was a good time to think about a powered lift option. After spending several days doing research, I determined that the Bulldog Powered Drive Trailer Jack, was the best product to meet my needs. etrailer has this product for the best price online, and offered free shipping, so for basically $100 more than a high quality none powered replacement jack, It was a no-brainer. My wife and I installed the unit on my trailer that was still on my tow vehicle in less than 45 minutes, and everything we needed minus a weather proof inline connector was included. It was so easy to install, and looked so good after installation. Because of the size and weight of my trailer, hooking and unhooking my trailer used to be a real chore for me, since I am older and have back problems. Then it was time for the true test, dropping the trailer for the first time. WOW! The spring loaded pin for the drop leg made it so easy! No more need for the several wood blocks we needed to lug around. Also it was now dark, so I turned on the lights. What a difference! The video does not do the lights justice. They clearly illuminate the rear of the tow vehicle, and front of the A-frame of the trailer. Then, by simply pushing the weather proof button, a chore I used to dread, that left me sore and sweaty, was now effortless! Quiet, smooth operation, and built in stops for extra protection. Very solid high quality construction, with all the features you need and want. The all weather design, powder coated metal parts make it easy to understand the reason why the manufacturer offer a 5-year warranty. I am only left with one question...why did I wait so long to buy this great product at the lowest price from Etrailer? 445335
Was used for our camper. Haven't used it at this time,but pretty certain it will be the best product ever purchased. 362522
