Expert Answers about Bulldog

  • 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...

  • 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.

  • 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...

  • 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...

  • 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...

  • Differences Among Square Drop Leg Jacks # BD182800, # BD182804, and # BD182815
  • The difference between Bulldog Square Jack - Drop Leg with Spring Return - Sidewind, # BD182800 and # BD182804 is that the latter comes with a handle. Both of these jacks can be used in tandem with BD182805. They all have the same: Bracket height: 27-2/5 inches Retracted, 39-9/10 inches Extended Drop-leg travel: 13-1/2 inches Lift: 12-1/2 inches Tubing width: 4 inches Plunger pin is positioned to the side Bulldog Square Jack - Drop Leg with Spring Return - Sidewind, # BD182815...

  • 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...

  • Can a Hole be Drilled in Gooseneck Trailer Outer Tube to Install Adjustable Coupler
  • You would need to contact the trailer manufacturer to see if you can safely use the trailer after drilling a hole for an adjustable coupler such as # BD0287610300. the outer tube would have to have one to use this type of coupler so provided there was a hole and the trailer manufacturer was fine with adding one then you could use it. The outer diameter of the coupler tube is 4 inches so the inner diameter of the outer tube needs to be slightly larger for it to fit. Another option,...

  • 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...

  • 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...

  • Will Bulldog or Ultra-Fab Landing Gear Fit a 2007 Skyline Toy Hauler
  • Most likely you need to go with the Bulldog Landing Gear Set # BD500161 because it has the typical inside to inside and outside to outside spacing of 15-1/2" and 17-1/2" respectively. This is the most common weld stop measurements which is why this should be what you need. If you go out to your trailer and measure your weld stop locations you can verify if they will fit or not. If they won't then you most likely need the Ultra-Fab Deluxe Landing Gear Set # UF17-943010. I have attached...

  • 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...

  • 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)...

  • Landing Gear Replacement Recommendation for a 2010 Keystone Montana Mountaineer Model 345DBQ
  • In order to pick out a direct replacement for the landing gear on your 2010 Keystone Mountain we would need to know the distance between the mounting brackets. Otherwise you could just have the brackets removed from your trailer by a qualified welder and then install the brackets that come with the Bulldog Tandem Landing Gear Set # BD500162. Either way this landing gear set would work well for you, you just might have to have the brackets of your trailer removed and then install the brackets...

  • Comparing the Bulldog Hitch Receiver Locking Pin to the Weigh Safe Hitch Receiver Lock
  • If your 2017 Ford F-250, whether you have the 3 inch receiver or the 2-1/2 inch, the two options you gave of the Bulldog Hitch Receiver Lock - Extra Long - Flush Design for 2-1/2" Trailer Hitches # BD580412 and the Weigh Safe Hitch Receiver Lock for 2, 2-1/2, and 3inch Hitches - 3-1/2inch Span # WS05 are both great options. The usable length of the Bulldog lock is 4 inches so it will work with a 3 inch receiver as well as the 2-1/2 listed in the description. I like the look of the Bulldog...

  • Replacement Trailer Jack Wheel for a RAM 2000 lb Jack
  • I may have an option that will work for you, however, the casters that we carry were designed as replacement casters for certain manufacturers. To determine if the Bulldog Replacement Heavy-Duty 6 Inch Caster, # BDCP555, will fit on your RAM 2,000 lb jack, you will want to take a few measurements on your jack. This caster was designed to fit 2 inch outer diameter jack tubes. Based on my research of your jack, you should have an inner tube with a 2 inch outer diameter. The next dimension...

  • 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...

  • Troubleshooting Latch Style Coupler vs Collar Lock Coupler For an A Frame Trailer
  • I can help you understand the difference between the latch lock style for couplers and the collar lock style. First let's talk about the latch style. If installed properly this style of coupler will work great. Determining if it is latched properly is a little more visually difficult than the collar style though. If properly installed the bottom of the latch mechanism should sit against the ball with no space. If your coupler is designed for a 2 inch ball size, you should be using...

  • What is the King Pin Diameter on the Bulldog Gooseneck to 5th Wheel Hitch Adapter

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...

  • Recommended Replacement Trailer Jack for Jayco Popup Tent Trailer
  • I think you are asking about a trailer jack for your Jayco popup. If so we have just what you need. For an a-frame camper I recommend a jack like part # BD1700100317. This is a sidewind jack that has a 5,000-lb capacity and has a 15-inch lift. This jack measures 8-5/8 inches when retracted and 23-5/8 inches when extended and has slotted bolt holes on the mounting flange that are 7/16 inches wide and 7/8 inches long. If a jack is not what you are looking for let me know and I will...

  • Wedge Style Latches Vs. Trigger Latches on A-Frame Couplers
  • The main difference between the wedge style latches and the trigger latches is in the capacity of the coupler. The lighter capacity couplers will use a trigger latch, whereas the higher capacity couplers will use wedge latches. For example, the Bulldog Heavy-Duty Cast Head Coupler w/ Wedge Latch # BD44125W0317 that you referenced uses a wedge latch and has a capacity of 12,500 lbs. An A-Frame Coupler # CA5100B uses a trigger latch and has a capacity of 5,000 lbs. Either style will...
