Video Transcript for Bulldog Trailer Jack BDCP555 Review

Today we're going to be taking a look at the Bulldog Heavy Duty Caster. This caster assembly is going to fit jacks with 2" tubing. The housing right here is going to be a steel construction, and it's going to have a nice corrosion and rust resistant finish on it. This does allow for a swivel design, so you can see how this portion that attaches to the jack swivels independently from the actual base. That's going to allow for easy maneuvering of your trailer. The wheel is a phenolic wheel which is a type of construction or material. That's going to be made from fiber filled plastic resin, and it's molded under extreme pressure.

What that means is that the wheel is a non-marking wheel, so if you have some more delicate flooring or a finished floor, it would be perfect for that situation, but it can be used outside or wherever. It's not going to leave any marks, and it's also corrosion and rust resistant, and it's going to perform well in very, very low temperatures, and very, very high temperatures. So a nice, solid, durable construction. The wheel diameter outer edge to outer edge is 6". The wheel width is going to measure 2" wide. This is going to have a capacity of 1,500 pounds, so keep that in mind, because that may reduce the overall jack capacity to that same capacity.

So 1,500 pound capacity and it may reduce the overall jack capacity to 1,500 pounds. The pin hole on the unit right here, that's going to measure 9/16", the natural diameter of the pin, this is included. That's going to measure 3/8" to secure the jack to the caster or the caster to the jack. Here on the inside you'll notice that it has the bolt head right there, but to the side of the bolt head is going to be the bottom of that tube. So from the bottom of that tube here on the inside to the center of the pinhole, I took a measurement and I got a measurement of 1". From the bottom of the wheel to the center of that pinhole measures around 8".

That's going to be the length added to the jack from the center of the mount hole. I do have a jack today that I can show you just how to install this onto. Very, very simple installation. This is a Bulldog jack, it's got a 2" diameter inner tube. What I would do is I'd place the caster right on there, then I would simply just line up my pinholes, and secure it with the included pin and clip, just like that. Really nice design, very easy to use. That's going to do it for today's look at the Bulldog Heavy Duty Caster..

Bulldog Removable, 6" Poly Caster Assembly for 2" Jack Tube - 1,500 lbs - BDCP555

Average Customer Rating:  4.9 out of 5 stars   (176 Customer Reviews)

Replaces or adds a 6" caster wheel to your Bulldog trailer jack with a 2" inner diameter jack tube. Includes a 2" long pin to secure to your jack's tube. Measures 6" in diameter and has a 1,500-lb weight capacity.


I had ordered an identical looking caster from someplace else claiming to be Bulldog brand and rated at 1,200. I installed it on a small trailer with not more than 100 pounds of tongue weight. The caster bent at the pivot point and was returned to Amazon. The etrailer caster is also a Bulldog brand and is rated for 1,500 pounds. It is holding up well.


This works perfect and do t need to kick it so the wheel would turn like the cheap one I bought at harbor freight. Makes it much easier to move my 5x10 trailer


Great product, very sturdy. Put it onto a 2009 Rockwood Freedom pop-up camper along with anew trailer jack. For the jack, had to do some minor grinding of bottom steel plate so jack could slide in all the way, alighting up with the three bolt holes. Very pleased with the two products.


Excellent. Heavy duty and solid. I can now move by camper side to side in my driveway without kicking the wheel. Also goes easily over small cracks.
I only wish there was a way to lock it to the jack to prevent theft.

Still working great and still wish there was a way to lock it to prevent theft. Thinking about putting a bolt in as the retaining pin and drilling a hole at the end to fit a small padlock. Would be great if you guys made a locking retainer pin with the lock on the end like receiver hitch locking pins.
Bill-Wichita - 09/28/2016


Fit perfect. Extremely convenient too for lining up the hitch to connect to the tow vehicle.


Attached is a picture of how I am using the unit.

I have a two wheel trailer type sprayer manufactured by Rears Corp in Oregon. They supply a Bulldog 158151 with the sprayer to support the tongue when the sprayer is disconnected from the tractor three point hitch

To reconnect to the tractor it is easier to have a unit with a wheel which is why I ordered the BD1541150301 and BDCP555. It did take me over two months to get delivery, but the unit works fine.

You may want to contact Rears Corp and see if they would like to switch to the unit with the wheel. The only down side is that the 158151 supports 2000 lbs and the BDCP555 oly 1500 lbs.


Good quality. After a couple of uses it was aqueky. I added lube. No issues after that.
A lot heavier made then my original. Rolls much easier and the wheel is built much better. Little wear after multiple uses.


This wheel fit perfectly on my Bulldog jack and works great on my Tow Dolly.


My utility trailer’s jack came with a “foot” which caused me to buy a trailer dolly to maneuver it within the tight confines of my garage. To say it was a pain is a gross understatement. I read all the positive reviews and comments regarding the Heavy Duty 6” caster and decided to give it a try. I cut the existing foot off and installed the new caster. Installation was easy and only took me about 20 minutes. What A Difference! Prior to installing the HD caster it would take me 10-15 minutes of struggling (along with a few choice words) to position the trailer. Now, even loaded with the ATV, it only takes me 2-3 minutes to accomplish the task. This is the best investment/addition I’ve made to my trailer. I highly recommend this product as it has made my life a whole lot easier. In addition, I’ve dealt with etrailer in the past and have been impressed with their quality of service and prompt delivery times. Thank you and I will continue to be a loyal customer


Heavy duty and good fit.


I have a RAM 2000 series trailer jack on my car carrier that I bought this caster for. The caster fit like it was made for my jack. I am very happy with how this all worked out.


smooth easy to move


Along with the Bulldog tongue jack, excellent combo. etrailer always good products and videos great bonus. Delivery right on promise date.


This jack stand wheel fits perfectly with the bulldog jack. Works great too!


X-Stream Clean Inc. N.Y.


The Caster wheel fit and made moving the camper trailer easier than the previous caster wheel.


great quality and works well.


This is a well-built and sturdy wheel. I bought it to replace the one that came with my jack and am very pleased with the quality. Great product!


Product arrived on time. Heavy duty trailer wheel works as specified. Allows one person to reposition trailer on a smooth paved surface.


I just tried it on my 6x12 enclosed trailer yesterday. The trailer was loaded with two mid-sized motorcycles. I was amazed that I could now actually steer the trailer as I pushed it across the garage floor. ( It was a constant struggle to steer the trailer with the wheel I had previously been using.) The body of this unit is constructed of much heavier steel than the one it replaced. The wheel material is nice and dense and rolls easily.
I was a bit surprised that the swiveling part of the caster does not use ball bearings. Instead it rides on a plastic disc. It is yet to be determined how long this setup lasts.

So glad I purchased this wheel. For normal storage, I attach the foot plate to the trailer jack. Whenever I decide to move the trailer, I just support the trailer tongue with a floor jack and swap on the heavy duty wheel. Takes only seconds to swap out and makes moving the trailer, even loaded, a breeze.
Douglas S - 09/28/2020


Arrived on time and fit great. Was easy to install. The trailer is so much easier to move around now.


Excellent caster. Using on my 2008 Trailmanor RV trailer. Bought this caster to replace an "under $20" caster I purchased a few months ago, which never fit the 2" jack post snugly and actually bent while trying to maneuver my trailer. I read other reviews on the Bulldog Heavy Duty caster that said it actually swiveled without having to be "kicked". The Bulldog fit perfectly, does swivel much better than the previous caster, and allowed me to position my trailer to its tight-squeeze location in my garage. Don't hesitate to pay a bit extra for this sturdy caster. I had considered buying a trailer valet ($300 plus) attachment, but no longer is necessary thanks to this caster.

Caster is still holding up. Turns well and allows me to maneuver my 3000 lb trailer to its exact placement in the garage.
David V - 09/02/2016


A little beefier than the one we had on our Aliner trailer whose tongue weight ia approx 350 lbs. I haven't really dragged the trailer around driveway yet, but it seems to change direction easier with the little interaction I did try (one tire was bootlocked and it's a hassle to remove a Brahma lock).

For a wheel that has 350 lbs of tongue weight, it works great. Now we can just hand push the trailer inout of the tight but paved space on the side of our garage instead of using the truck.
John - 10/14/2019


Item was as described and fit perfectly. This will make moving my utility trailer much easier.


This is a great addition to my new trailer. It replaces the stock flat pad and allows me to relocate the trailer while not connected. Love the latch pin that allows easy removal when towed with a lower hitch.

im not fully satisfied with this product. I find the swivel needs much attention and readjusted as well as the unit often fills with water and can be rusty what I remove the wheel. It does the job but needs attention

  • Does Trailer Jack Caster BDCP555 Have a Ball Bearing Swivel
    Jack caster # BDCP555 does not feature a ball bearing swivel. Instead, it uses a combination of a thrust washer and a flat washer for the swivel feature.

  • 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...

    We do have replacement wheels for Bulldog jacks but they are designed with a 2-inch diameter jack. The Bulldog wheel we offer is part # BDCP555.

  • Caster Wheel For 5,000 lb Capacity Trailer Jack
    There are not any caster wheels that we carry that are rated for that 5,000 lb capacity. My recommendation for a durable wheel is the Replacement Heavy-Duty # BDCP555. This is rated for 1,500 lbs and is the strongest caster we carry that isn't for a specific model of jack. People use these caster wheels on higher rated jacks like you mentioned and it will fit, but they are only rated for that smaller capacity.

  • How to Install the 6" Bulldog Heavy-Duty Caster # BDCP555
    The 6" Heavy-Duty Caster # BDCP555 from Bulldog is designed specifically for 2" Bulldog jacks which come with a pin hole. Since the installation of the caster wheel is simple (and it is a replacement part) Bulldog doesn't include any instructions. Since your jack doesn't have a pin hole, if you were to drill one out I would make sure that it is slightly larger than the pin. The reason being that you don't want the pin to seize inside the jack in case you would need to remove or replace...

  • Fit of Bulldog Jack Caster Wheel Replacement BDCP555
    The Bulldog Heavy-Duty 6-Inch Caster Wheel # BDCP555 will work on any jack whose round tubing diameter is 2-inches. The diameter of the snapper pin is indeed 3/8-inch. This wheel assembly is rated for 1500-lbs, which could be more or less than the jack with which it is used. The lower rated item, the jack itself or the wheel installed on it, always determines overall capacity.

  • Replacement Caster Wheel for Haul Master Jack with 2" Tube
    I have a solution for you, but the # PS1400750340 is not going to be the heaviest rated caster wheel for your Haul Master jack. You can instead use the # BDCP555, which is rated for 1500-lbs and will work just fine for you as long as the tongue weight on your trailer is not greater than 1500-lbs.

  • Caster Wheel for Bulldog 2K Round, Snap-Ring Swivel Jack
    A caster wheel pivots independently of what it is attached to so the inner tube of Bulldog jack # BD151443 would not have to rotate. Take a look at wheel # BDCP555. This is a caster you can use with the jack. In the linked video you can see that the wheel rotates independently from the shaft that attaches to the jack. Keep in mind that even if the jack capacity is higher than the wheel the addition of the wheel limits the capacity of the jack; in this case it would be limited to 1,500 pounds.

    When looking for a wheel, you will go by the outer diameter of the inner tube of your jack. In this case you state the inner tube is 2 inches so you could go with the Pro Series 6", Detachable Caster with Pin, # PS1400750340. This wheel/caster has a weight capacity of 1,200 pounds. Another option would be to go with the Bulldog Heavy-Duty 6 Inch Caster, # BDCP555, which has a weight capacity of 1,500 pounds. I have included a video for you to check out.

  • Can a Bulldog Replacement Jack Caster Wheel be Used on a Ram Jack
    We do not carry Ram brand parts but one of our wheels might work. Replacement wheel # BDCP555 will fit around a 2 inch diameter tube. Pro Series wheel # PS1400750340 also fits a 2 inch tube. These are going to be the best options. Both wheels attach to the jack with a pin. Please note that even if the jack is rated for 1,200 pounds you will have to go by the wheel's capacity since it is the lower rated component. Wheel # BDCP555 is rated up to 1,500 pounds.

  • Replacement 2,000 Pound Bulldog A-Frame Trailer Jack
    Bulldog jack # BD155033 would be a comparable replacement for the jack you have on your trailer. I believe the jack you have is one that they only sold to trailer manufacturers. The outer diameter of jack # BD155028 is 2-1/4 inches. Measure the outer diameter of the outer tube of your jack to confirm it is also 2-1/4 inches. If you need to add a when you can use # BDCP555. But the wheel is only rated up to 1,500 pounds so you would have to stay under that 1,500 pounds.

This has a 6 inch wheel. In the same way, the Pro Series Detachable Footplate w/ Pin for 2" Diameter Jacks - 2,000 lbs to 5,000 lbs # PS1400700340 will work. With either option you will need a longer pin because you will be using the jack leg's outer diameter.

  • Trailer Jack and Wheel Caster Recommendation with 15 Inches of Travel and a 1,500 lb Capacity
    I have a solution for you, you will need to get the Bulldog Round, A-Frame Jack # BD1700100317 that you referenced, and then you will need to install a Replacement Heavy-Duty Caster # BDCP555. The # BD1700100317 has a 5,000 lb capacity, and the # BDCP555 has a capacity of 1,500 lbs you would have a jack setup with 15 inches of rise, 1,500 lb capacity and has a caster wheel.

  • Jack Caster for Enclosed Cargo Trailer
    The Bulldog Removable Caster, part # BD500245 will work just fine for you if your existing jack has a 2 inch diameter inner pipe. The caster itself has an 1200 lb capacity, so using it will limit the capacity of your jack to 1200 lbs. Part # BDCP555 would also fit a 2 inch diameter pipe, and offers a 1500 lb capacity.

  • Will Bulldog Replacement Caster # BDCP555 Fit Bulldog A-Frame Jack # BD155022
    The Bulldog Replacement Heavy-Duty Caster, # BDCP555 is indeed compatible with the Bulldog # BD155022 jack that you have. Keep in mind that the capacity of the jack will be decreased to 1500 lb when using the caster. Since the jack only needs to support the tongue weight of the camper and not the entire weight, this should not prove to be a problem with a pop-up camper.
