  • Replacement Key for a CCP Bulldog Hitch Lock
  • Since you said CCP hitch lock it sounds like you have the Bulldog Lock part # BD580404 as this lock has CCP on the key and has the key number on the other side of it. All you would is # CKEY-FS. Enter the key number in the space provided on that product page and we'll ship you out a replacement key.

  • 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...

  • 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...

  • 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.

  • 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...

  • 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...

  • 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...

  • Adding an Electric Motor to Bulldog Square Jack # BD182701
  • The motor that fits Bulldog jack # BD182701 is powered drive kit # BD1824200100. The shaft on the jack is 1 inch in diameter and the pin hole for the crank is approximately 5/16 of an inch. The motor mounts to the side of the jack as you can see in the picture I included. Adding the motor limits the jack capacity to 12,000 pounds. I have linked a video review of the powered drive kit for you.

  • Powered Landing Gear Motor Recommendation for 20K-lb 5th Wheel Trailer
  • 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.

  • Replacement Handle and Gear Assembly for the Bulldog Weld On Square Jack with Footplate # BD195354
  • I spoke to my contact at BullDog and, if your Drop Leg jack is the Bulldog Square Jack with Footplate - Drop Leg - Sidewind - 15 inch Lift - 5,000 lbs, item # BD195354, the correct replacement gears are the Replacement Sidewind Gear Kit, item # BD500106, and the correct replacement handle is the Replacement Sidewind Handle, item # BD500105, You should be able to find the model of your jack on a sticker, normally near the handle of the jack, or stamped in the lower portion of the jack...

  • 2-Motor Powered Landing Gear Recommendation for 2010 Keystone Montana
  • The Montana by Keystone had a special set of landing gear made for them by Lippert. So typically we recommend the part # LC178653 for the lead leg and part # LC178652 for the follow leg. The difference is the mounting bracket location that's on the jack. So your best option for a dual motor landing gear setup would be the Bulldog kit part # BD500161 which can have the motors inverted when installed like what you see in the attached picture. This will give you more clearance. The mounting...

  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • How Does the Bulldog 10k Electric 5th Wheel Landing Gear Set Install on a Trailer
  • Installation for the Bulldog Electric 5th Wheel Landing Gear Set, # BD500161, is very straight forward. For the jacks themselves, the 2 brackets per jack will get welded to the vertical part of the trailer frame. This will not require drilling into the frame to mount the brackets. The legs of the jacks then attach to the brackets. The control panel can be mounted anywhere that is convenient to you. The wiring seems complicated but really it is just power and ground for the switches and...

  • Converting a Fifth Wheel Trailer to Be Used with a Gooseneck Hitch In a Shortbed Ford F-250 Truck
  • The best way to convert a fifth wheel trailer to the gooseneck hitch setup in your short bed Ford F-250 is to use the Ranch Hitch Universal 5th-Wheel-to-Gooseneck Coupler Adapter w/8 inch Offset for Short-Bed Trucks, item # AM3139. This is a semi permanent installation that works very well. If your truck has a bed shorter than 6 feet, you will need to measure to be sure that you will have enough clearance for maneuvering and pitch and roll of the trailer before deciding to order the...

  • Availability of a Dual Leg Electric Trailer Jack for a 3 Horse Trailer with Living Quarters
  • I have posted a link below to the electric powered jacks that we carry. At this time we do not carry hydraulic trailer jacks. 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...

  • 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...

  • 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...

  • Short Trailer Jack Recommendation for a 7000 lb A-frame Horse Trailer for Tailgate Clearance
  • I went out to my warehouse a pulled a few different jacks that I think will work for you. The Bulldog Round, A-Frame Jack, # BD1550101344, measures 14-1/2 inches from the bracket to the top of the jack, but you will lose an inch of lift with a 13 inch lift. You do, however, gain an increase in weight capacity at 3,000 lbs with this jack. Our best option may be the Pro Series Round, A-Frame Jack, # PSRV20000103. This jack measures only 13 inches from the mounting bracket to the top of...

It mounts to 50 degree A-Frame Tongue and will couple to a 2-5/16 in hitch ball. It has a 12,500 lb weight capacity.

  • 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...

  • Fit of Bulldog # BD500162 Replacement 5th Wheel Landing Gear on 2004 Keystone Montana Big Sky
  • The Bulldog # BD500162 landing gear bolts to its brackets, but the brackets would weld to the trailer frame. You should be able to reuse your existing brackets as long as they're not damaged or excessively corroded. The jacks would be the correct replacement for Lippert, Venture, and Atwood landing gear, as well as those from a few other manufacturers. The sure way to tell is that if the distance between the mounting brackets (underside of top bracket to top of lower bracket as shown...

  • Landing Gear for a 2009 Heartland Bighorn 5th Wheel Trailer
  • I did some checking and the 2009 Heartland Bighorn 5th wheel trailers were built on a Lippert chassis and have other Lippert components so the landing gear will also be Lippert. If you just need to replace legs then the lead leg is # LC179013 and the follower leg is # LC179014. If you need the whole set use # LC333964.

  • Is There A Standard Bolt Pattern for Mounting a Jack to a Trailer A-Frame
  • Most jack manufacturers including Fulton, Bulldog and Dutton Lainson use slotted holes in the jack mounting flange. Three inches apart center to center is considered industry standard. Since the holes are slotted, there will be a bit of wiggle room if the holes in your trailer A-frame aren't exactly 3 inches apart.
