What our customers are saying:

WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!

  • How to Choose the Correct Replacement Trailer Jack With Enough Ground Clearance on Rough Terrain
  • When choosing a jack for your trailer you will want to remember that the jack is not going to be lifting the entire weight of the trailer. You should choose a jack that exceeds the tongue weight of your trailer when it is fully loaded. The tongue weight of a trailer is typically calculated as 10 to 15 percent of the trailer weight. I would recommend finding the gross trailer weight rating (GTWR) which is the maximum weight that your trailer can support and choose a jack that is rated...

  • 2-Speed Electric Trailer Jack to Replace Manual Jack on 3 Horse Slant Trailer With Living Quarters
  • The Bulldog Square Jack you referenced, part # BD182400, is a weld-on single speed jack rated at 10,000-lbs lift capacity. This jack can be used with a single-speed power drive kit, part # BD1824200100. For two-speed operation you will need a jack with a two-speed planetary gearbox, such as Bulldog 2-Speed Jack, part # BD183401. With this jack you can use powered-Drive Kit # BD1824180100 but please note that my contact at Bulldog advised that when using the power drive kit on this jack...

  • Replacement Key for a CCP Bulldog Hitch Lock

  • How to Wire the Bulldog Powered-Drive Trailer Jack # BD500200 on a Trailer with No Battery
  • The Bulldog Powered-Drive Trailer Jack, item # BD500200, only has one wire, the power wire. This jack attaches to ground through the mounting hardware and the trailer frame. When wiring the jack to your 7-Way trailer connector you will need to make sure that the ground wire from the 7-Way trailer connector is attached to the trailer frame to provide ground. You will then attach the power wire to the 12 volt accessory circuit inside the 7-Way connector or splice into the wire the is attached...

  • Coupler Locks for a Bulldog Style Coupler
  • Yes, check out the EZ Lock Trailer Coupler Lock # BLTL-20-40D. This coupler lock is compatible with Collar-Lok Couplers and then use for a pin style lock to slide through the coupler you would want the Masterlock Trailer Coupler Lock part # 2847DAT.

  • Replacement Follower Leg for a Venture VMC900L Landing Gear Set
  • The only follow leg I can recommend you use with your Venture landing gear would be the part # LC179014. Stromberg Carlson makes the Venture landing gear, that is the brands are different but the jacks are the same. I cannot recommend you install a Bulldog motorized follow leg to go with your Venture lead leg. This leg has 29-9/16 inch tall outer tube and 15 1/2 inches between mounting brackets. The only other option would be to replace your current landing gear with the landing gear...

  • Does Gear Box on Outside of Bulldog Jack have to be Removed to Install a Powered Drive Motor
  • I spoke with my contact at Bulldog about powered drive kit # BD1824180100. He said that you can use it with the Bulldog 2-speed manual jack # BD183802. All you have to do is to disassemble the gear box to remove the handle that goes through the jack because the powered drive kit has one that replaces it.

  • What is the King Pin Diameter on the Bulldog Gooseneck to 5th Wheel Hitch Adapter
  • The standard king pin dimension for a semi-trailer is 2 inches diameter, where the fifth-wheel jaw wraps around the king pin. I went out to the etrailer.com semi-trailer on our lot, see link, and produced a short video showing both of the king pins in close proximity to each other for you to see. The king pin on the Bulldog Gooseneck-to-5th-Wheel Trailer Coupler Adapter, # BD0289580300, is an industry standard 2 inch king pin and will work in a semi-tractor fifth-wheel hitch, as long...

  • Which Bulldog Powered Drive Kit Works with 2 Speed Bulldog Landing Gear Trailer Jacks
  • A 2 speed jack will have a second gear set attached to the jack. It would either be operated by taking the handle off of the first speed and moving it to a separate spot on the jack for the second speed or, more commonly, the crank handle will be pushed in or pulled out to engage the second gear set. Take a look at the Bulldog 2-Speed Jack, # BD183816, as an example. It does matter between single and 2 speed when you are looking to add a powered drive kit. The powered drive, # BD1824200100,...

  • Low Profile Trailer Jack Recommendation for Better Tailgate Clearance
  • Sounds like you are looking for a lower profile jack for your trailer so that the tailgate of the vehicle does not interfere with it. I went to our warehouse and was able to locate an a-frame jack that measured less than 12 inches from the bracket up. The Bulldog Round A-Frame Jack, # BD155032, comes in just under 11-1/2 inches which included the handle. I have attached a picture to illustrate the measurement. This a-frame jack has a lift capacity of 5,000 pounds and mounts to any...

  • Comparing Bulldog Powered-Drive Jack Kits # BD1824200100 and # BD1824180100
  • The difference between the two Bulldog powered-drive jack kits you referenced, parts # BD1824200100 and # BD1824180100, is that the first one is for a single-speed jack and # BD1824180100 is for a 2-speed jack. Both are rated for 12,000-lbs jacks. My research did not reveal any photos or specs for the Towmaster THD214 dump trailer so I cannot state whether these kits are suitable. If you can confirm that the trailer uses a 12K Bulldog jack and confirm if it is a single- or 2-speed type...

  • Does the Bulldog Square Jack # BD182815 Come with a Handle
  • The crank for the Bulldog Square Jack # BD182815 is sold separately. You would want a Replacement Bulldog Sidewind Jack Crank Assembly w/ Horizontal Clevis # BD800090 if you would like a horizontal clevis or a Replacement Bulldog Sidewind Jack Crank Assembly w/ Vertical Clevis # BD015181 if you want a vertical clevis. The difference between the clevis designs is in how you plan to store the handle when it is not in use. The difference is in the how the handle hinges to allow it to be...

  • Which is Better, a Side Wind Trailer Jack or a Top Wind Trailer Jack
  • You would choose a side wind or top wind jack based on several factors. Each has its advantages. If clearance is an issue for the radius of a top wind, then you would choose a side wind. The opposite is also true. It is my experience that a side winding jack is easier to turn. However, if the tongue is low to the ground a top wind would be a better option because you would not have to bend down as much and it would not be as awkward to turn. A side winding jack normally has inner components...

  • Difference Between the Bulldog Wedge and the Collar Lock Couplers
  • The distance between the center of the ball hole to the center of the circle used for A-frame jacks on the part # BD44125W0317 that you referenced is 12-1/2 inches. I confirmed this with my contact at Bulldog. The advantages between the latching styles of the wedge latch in the # BD44125W0317 and the collar lock like in part # BD028499 is largely personal preference. But the wedge is easier to lock with an anti-theft device. The collar lock style is more rugged and crude design with...

  • We do offer several brands and models of replacement 5th wheel landing gear motors, including the Atwood 75391 that you referenced. This motor is rated for applications up to 5000-lbs tongue weight. We also offer Stromberg Carlson's # LG-217884 Motor and Switch Kit, rated for 6000-lbs. The motor alone is also available as part # LG-142178. Pricing for all is available on each product page and both Stromberg Carlson motors carry a 1-year warranty and 2-years for the Atwood.

  • Difference in Side Wind Operated A-Frame Jack and Top Wind A-Frame Jack
  • The choice between a side wind jack like the Bulldog Round, A-Frame Jack - Sidewind, part # BD1700100317, and a top wind jack like the Bulldog Round, A-Frame Jack - Topwind, part # BD155032, will usually be for clearance issues. A top wind jack will be used when there is something on the trailer that will interfere with the rotation of the side wind handle on the jack and a side wind jack would be used if there is interference for the top wind jack handle. If the clearance issues are...

  • Landing Gear Recommendation for a Heavy Toy Hauler Fifth Wheel
  • Sounds like your 2007 33 ft. Weekend Warrior 5th wheel toy hauler is pretty heavy if it has caused the landing gear of your trailer to fail twice so far. Between the Bulldog Landing Gear part # BD500161 and # UF17-943010 that you referenced I would go with the Ultra Fab as it has a 12k capacity and the Bulldog has a 10k capacity. Also the Ultra Fab has more positive reviews from the customers we have that have used them. The Ultra Fab set will require you to weld on new mounting...

  • Will Bulldog Electric 5th Wheel Landing Gear, part # BD500161 Fit Without Welding
  • There are a couple of things that need to be considered for installation of the Bulldog Electric 5th Wheel Landing Gear, part # BD500161. The welded stops that are on the legs of this landing gear are in specific locations, and require the brackets on your trailer to be attached in corresponding positions so that the landing gear does not shift when installed. I have attached a drawing that shows the dimensions needed for this landing gear. Please note that the brackets are placed in...

  • The replacement parts we have for the Bulldog Square Jack # BD182500 are a Replacement Gear Kit # BD500212 and a Replacement Screw and Nut Kit # BD500217. These are the two most likely aspects of the jack to be causing your problem. I have attached the only two diagrams we have related to this trailer jack. The inner tube is held to the outer tube by the screw and nut assembly.

  • How To Maintain Charge In Trailer Battery That Will Run A Powered Trailer Jack On A Pace Trailer
  • You will want to use a standard 12 volt deep cycle trailer battery to operate the Bulldog Powered-Drive Trailer Jack, part # BD500200. You will NOT want to use a trailer breakaway battery. The breakaway battery is not designed to power other trailer accessories or lighting, it is just designed to operate the breakaway system. To keep the trailer battery charged you will need to run a 10 gauge power wire like the, part # 10-1-1, from the 12 volt power pin (# 4 terminal at 11:00 position)...

  • If you are needing a lock for the Bulldog Collar-Lok Coupler w/ Low-Profile Latch, part # BD028287, and a lock for the hitch receiver on your vehicle that are keyed alike you can use the Deadbolt brand lock. For your Bulldog coupler you would have to use the Deadbolt Trailer Coupler Lock, part # 28012. This is a coupler lock with an inside width of 3-3/8 inches. I pulled the Bulldog coupler from our warehouse and measured the size of the lock pin that goes in the coupler. It measured...

  • How to Lubricate the Bulldog Top Wind Round A-Frame Jack # BD155032
  • According to the installation instructions for the Bulldog Top Wind Round, A-Frame Jack, # BD155032, the only maintenance needed is applying a light machine oil to the stem that the handle attaches to. The installation instructions also recommend thoroughly rinsing the jack with clean water before lubrication. I went out to the warehouse and looked at one of these jacks and there is no point in the top of the jack for insertion of grease. You could insert grease from the bottom of the...

  • Availability of a Dual Leg Electric Trailer Jack for a 3 Horse Trailer with Living Quarters

There is an option for converting the Bulldog Square Jack - Drop Leg w/ Non-Spring Return - Sidewind - 12-1/2 inch Lift - 12,000 lbs, item # BD182400, to an electrically operated jack. The Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity, item # BD1824200100, can be used with the # BD182400 jack. The final option that we have that may...

  • How to Remove a Stuck Bulldog Locking Hitch Pin from Trailer Hitch
  • Sounds like the internal ball-bearings on your Bulldog Lifelong Trigger-Style Coupler Lock and 2" Trailer Hitch Receiver Lock, # BD580404, may be stuck. Try using a penetrating spray lubricant, like the UltraLube Biobased Spray Lubricant and Penetrant # L10444. The spray lubricant will penetrate to the locks bearing and help break up any contaminates that may be causing the lock to stick. Plus, the spray will make separating the lock easier due to lowering the surface resistance of...

I have included a product demonstration video for your reference, and a helpful article about trailer couplers.

  • Difference Between Bulldog BD500170 and BD500161 Fifth Wheel Landing Gear
  • The only difference between the two Bulldog Landing Gear kits, BD500170 and # BD500161 is the weight capacity. The BD500170 has a 7000 lb capacity, while the BD500161 has a 10000 lb capacity. The BD500170 has been discontinued and is no longer available. When mounted, either jack will have a 17-1/2 inch distance between the bottom of the upper frame clamp to the top of the lower frame clamp. The jacks do include frame clamps, so if the frame clamps on your existing landing gear don't...

They are the same part except BD178201 is our part number for it and 1782010117 is the manufacturers part number for it. These jacks would not be the best option for use as stabilizers for your Mercedes Sprinter. I recommend something like # UF48-979004 which is a set of 4 stabilizers rated for 6,000 pounds each. As long as you have 11 inches or more between the ground and the bottom of the vehicle frame these...
