Video Transcript for etrailer Removable Removable Poly Caster Assembly Review

Today, we're gonna be taking a look at a nice accessory for your trailer jacks. So if you have a inner tube of two inches in diameter, we're gonna be able to put this little wheel on here. The nice thing about this wheel is whenever we're a little bit off getting our ball mount lined up with our coupler we're gonna be able to put this thing on so we can actually move it around. So this one is gonna be able to completely rotate around. It comes with the pin, which is awesome. So all you have to do is just slide it on and snap it in to place.

So the wheel is gonna have a diameter of 6 inches. It's about 2 inches thick, so it shouldn't sink down into the ground at all. And it is made of a polyolefin material which is gonna be extremely hard, so you don't have to worry about it cracking over time. If it does crack, maybe you have it for years and years and years, we do have a replacement wheel, so you don't have to buy the whole entire thing. I do like how it kind of swivels around so you can get that angle that you need.

You can move it wherever you really need, which is always a plus. And then everything else besides the wheel is gonna be made of a steel material which has a zinc-coated finish so it's not gonna rust away either. So it's gonna move nice and freely for a long time. The lighter the load, it's gonna be a little bit easier to move. So with nothing on our trailer, this is a pretty big trailer, but as you can see, I can really deviate right and left pretty good.

I can roll it this way, roll it back. I'm not the strongest fella. So it is pretty easy, but we do wanna make sure we're not gonna overload it. Yes, this jack can have up to 3000 pounds on it but the foot plate is gonna have a capacity of 1200 pounds. So we don't wanna overload that 'cause then we might bend some material or crack our wheel.

Whether you have a trailer for work or play this is gonna make it a little bit quicker to get it lined up with your ball mount and also it's gonna be a little bit easier to maybe store this trailer. So if we have it completely unloaded, we wanna get it in a certain little spot and we can't really back up perfectly to it, you can use this to kind of wheel it around and get it exactly where you need. So you have a little bit more space at your house, at your business, wherever it may be. I do think that this is pretty much an essential thing when it comes to trailer jacks, might as well get a wheel so you can move it, just enable your trailer to do a little bit more. When it comes to a wheel on the bottom of your jack, we have a couple options on our website. This is a 6 inch wheel. Some of 'em are 7 inches wheels, and then some of 'em actually have two. So if you want to increase the surface area if you're parking it in the grass and you really don't want to sink down, you can get one that'll have two wheels, so it'll double your surface area. So it won't sink down. Just know we have a lot of different options. We just wanna make sure we get one that's gonna be the right weight capacity for the load that we have. And that's pretty much it for our look at the 6-inch caster for our trailer jacks..

Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube - 1,200 lbs - JC-101

Average Customer Rating:  4.9 out of 5 stars   (205 Customer Reviews)

Caster attaches to a 2" jack inner tube to make it easier to move your trailer. Easily removes for travel. Reduces jack's overall capacity to 1,200 lbs.


Fits my utility trailer. Perfect with a 2 inch opening. Fantastic replacement for my JetSki.


Works enabling me to easily move my utility trailer, either loaded or empty. Like that it is pinned so I can remove it when trailer is connected to truck so that jack is not too low to ground/pavement. Plus, it allows me not to have to raise/lower the jack as much. Great investment.


I really like this wheel. I did have to cut off a piece of metal that was welded on the bottom of my jack but I don't think that would be the case with most hitches. Once I got it cut off it was a matter of just slipping the wheel receiver over the jack pole and installing the pin. I was able to very easily push my heavy duty 5' x 8' utility trailer around even over a dirt area with no trouble at all! Very glad I bought it. I may have to remove it during towing because it does hang down a bit but it's easy to take off with the provided pin. I received my wheel in just a few days after I ordered it.


I did receive today and the wheel looks great. Looking forward to using it. The only thing I want to mention is that I was given the opportunity to pay a little more and I did in order to receive faster, but did not.


Feels very beefy and was very happy with price. I had to drill the caster wheel's pin holes to 1/2" in order to be able to able to run the pin through bottom of the jack. My jack may not be perfect, bit I still would have rather drilled the caster over the bottom of the jack/cut off some material from the bottom of the jack.


Combo of this part #JC-101and Item Item #PS1400700340 allows me both options. The construction quality seems great, and the parts were just what I wanted and at an excellent price. Easy half-hour conversion of my old jack, with only a grinder and drill. etrailer took good care of me, items well packaged, and I received them faster than promised.


Very pleased with this product! It fit my little 5 X 8 cargo trailer absolutely perfectly! Thank you!


Better prices-High quality-Fast delivery


Fits perfect


This caster wheel was used to replace the fixed plate on the original jack foot. It fit perfectly over the tube which only required drilling two holes for the pin.


I got my handle fixed on Jack on my large trailer . Had trailer 20 years , toot old tool for modern supplies to supply Jack handle . Trailer frame is A frame / center . This wheel is for replace I have off of camping trailer / electric Jack top . Some day I will need to put strong steel plate to support A frame



Working out fine. Had improvise how to mount it. No problems.


Ruggedly built, swivels easily under weight, and a very reasonable price for the quality.


My order was shipped immediately and it fit perfectly with no additional drilling with one minute installation. Highly recommend the product!


Did exactly what I wanted.


A perfect fit that now allows me to actually move the trailer by hand.




China built. Time will tell how long it will last. Odds aren’t good.


This wheel assembly fit snuggly and was straight-forward to install. It makes moving my utility trailer around a simple one-person operation. It is so much easier to roll the trailer up to the hitch than to try to back the vehicle up to align with the trailer. With this wheel on the front I can unhitch the trailer and walk it anywhere I want, and turning it around is no longer a big deal. Our driveway is difficult to turn the trailer around and I HATE trying to back the trailer into the drive. (People are not very patient and they honk and make rude gestures!) This is the First item I bought after I brought my "new" utility trailer home. It makes it such a breeze to use the trailer since it only takes 5 minutes for one person to roll it over, hook it up, pop off the wheel (store it in the trunk) and GO!


I recently bought a 5 x 10 landscape trailer to replace my small 4 x 8 utility trailer. I soon found I could not move the new trailer around by myself. I had put a bolt on jack with a wheel on the straight tongue of the small trailer and it was simple to move around even on grass. The bigger trailer had a welded jack in the A-frame tongue with a welded sand pad. I received this 6" wheel in three days, cut the sand pad off and drilled a hole through the jack shaft. Wheel installed perfectly in about 20 minutes. I was able to guide the trailer to the back yard and position it behind my garden shed without any help. Well worth the money. I would definitely recommend to a friend.


I have found that the products available through etrailer are step above many other outlets for trailer needs. This jack wheel is being installed on my catamaran trailer and has proven to enhance my boat trailers handling to be great and the wheel moves easily across the ground. Highly recommend theis product and etrailer.


I had a great experience with etrailer. Troy was very helpful when I called. I had no idea what I was looking for. My boss handed me a broken wheel and told me to replace it. I didn't have an item number, a brand name or any other useful information. I described what I needed to Troy, and he was able to figure it out in a few short minutes. I still needed approval from the boss to actually place the order, but once I got the okay, I called back. This time, Tammy helped me, and like Troy, she was a pleasure to work with. I appreciated their friendly and helpful service. Oh, and the wheel works like a dream!


Installed in about 2 minutes. Arrived within a few days using value shipping. Perfect fit for what I was needing for my tailgate trailer.

Drew M.


this has been a great addition, even a year later.


I ordered a wheel for my trailer jack and these people replied whithin minutes and it was shipped the next day. They kept mr informed about the shipping and when I received the package I had a e-mail asking me if everything was okay. I would order again from this company in a heartbeat. Thank You


solid product, fit like a glove, very p leased....


I received my removable trailer jack caster. I was expecting to get a cheap flimsy product. I was surprised at the quality item I received. Its well made and very sturdy. This is the second item I've ordered from etrailer and I've been very happy. I will definitely continue to shop with them.

  • Does the Ram Removable Caster Assembly Swivel and Include a Steel Bearing
    The Ram Removable Caster Assembly, # JC-101, is a swiveling caster when attached to the jack. The caster assembly uses a nylon bushing at the swivel point between the connected mounting tube and the wheel assembly.

  • Correct Caster Wheel for RAM 2000 Series Jack on Aliner Trailer
    I do have an option for you but we can't confirm Bulldog jack caster wheels will work with a Ram Series 2000 Trailer Jack. That said, we do offer caster wheels for this jack, the Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube part # JC-101. This jack wheel is rated for 1,200 lbs of tongue weight which is not the full weight of the trailer so it will be more than enough for the Aliner.

    We do offer caster wheels for Ram Trailer Jacks like the 2000 Series, the Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube part # JC-101. That said, these are only avavailbe in single wheel configurations and they will reduce the weight capacity to 1,200 lbs.

  • Available Trailer Jack Caster Wheels
    You can see all of our available jack caster wheel assemblies on the linked page. These fit on a 2-inch-diameter jack tube, such as # BD500245. If you can find a brand name or part number on your jack that will help to narrow down the correct parts, but as long as the tubing diameter matches up you should be fine using a different brand of wheel. We have plastic wheels in various dimensions, such as the 6-inch # JC-101 and also a steel wheel # JC-102.

  • Recommended Replacement Taillight Lens for a 2017 Forest River Flagstaff 176LTD
    If you're meaning a lens, then you could use the Replacement Lens for RVSTL61 and RVST61 Tail light # AST61B which look identical to the OEM taillights, however to be sure you'd need to measure your current lens and compare it to # AST61B. This lens measures 8 5/8" wide 3 3/16" tall, and 2 1/4" deep and will work directly with the RVSTL61 and RVST61 tail lights. If you need something different feel free to include some measurements and a photo of what you're looking for and I'd be happy...

  • Does Wheel Caster JC-101 Fit 2,000 Capacit Ram Jack
    If the Ram 2000 series you are referring to is the Ram Round A-Frame Jack part # TJA-2000-Z yes, the wheel caster part # JC-101 will fit and work well. This will reduce the jack capacity to 1,200 lbs though.

  • Wheel Compatibility with EJ-3520-BBX Electric Trailer Jack
    The Electric Jack w/ Footplate - A-Frame - 25-1/8" Lift - 3.5K - Black # EJ-3520-BBX has a 2 inch outer diameter lower tube so you can use the Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube - 1,200 lbs # JC-101 but the wheel will reduce the capacity to 1,200 lbs. The wheel will always be the limiting capacity on a jack like this.

  • Does the Trailer Valet JXS Trailer Jack Come with a Wheel
    The Trailer Valet JXS Trailer Jack part # TV64FR comes with a footplate only. There isn't an exact fit wheel option for this jack but there are likely other options that will work. That said, these wheels reduce the lift/support capacity of the jack quite substantially. The Removable, 6" Poly Caster Assembly part # JC-101 would be a compatible add-on wheel option limited to 1,200 lbs.

  • Replacement Wheel To Fit Electric Jack with Footplate Part # EJ-3520-BBX
    Yes, I went out to our warehouse for you and can confirm that the Ram Removable, 6" Poly Caster Assembly part # JC-101 will fit the Electric Jack w/ Footplate part # EJ-3520-BBX. Please note that using this wheel on your jack will reduce its capacity to 1,200 lbs. This will be the case for any a-frame electric trailer jack with a wheel attached.

  • Can Caster Wheel Be Added to Trailer Valet TV64FR 5K Capacity Trailer Jack
    You could add a caster wheel like part # JC-101 to the # TV64FR jack, however if you were to do so, the 5K capacity of the # TV64FR jack would be reduced to the 1200 lb capacity of the caster wheel. If the tongue weight of your loaded trailer is less than 1200 lbs, adding the caster wheel would be an acceptable modification.

  • Distance From Mounting Bracket To Bottom Outer Tube On Trailer Valet JXC Trailer Jack
    In regards to the Trailer Valet JXC Trailer Jack part # TV94FR, the distance from the mounting plate to the bottom of the outer tube is 7" which you can see in the photo below. I don't have any confirmed fit caster wheels for this jack but you may be able to make one like the Ram Removable, 6" Poly Caster Assembly part # JC-101 work via modifying if it doesn't bolt up.

    For your replacement trailer jack, I recommend the Pro Series Round, A-Frame Jack w/ External Gearbox - Sidewind - 14" Lift - 2,000 lbs # PSRV20000103. I recommend using the Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube # JC-101 with this to give you the wheel you are currently missing as well, but that won't give you much clearance for travel when it is installed, so I recommend removing it for towing. This is easy with the included pin and clip. Another option is to change...

  • Recommended A-Frame Jack Caster Wheel for 1-5/8 Inch Outer Tube Jack
    The Removable Wheel for Dutton-Lainson A-Frame Trailer Jack Model 6418 # DL22414 is a fit for a 1-3/4 inch outer diameter tube. This is going to be the closest wheel to the 1-5/8 inch outer diameter tubing on your inner diameter jack leg. I don't recommend mounting a caster to the bottom of a foot plate as that could cause more issues and would still not fit properly without customization. Your other option would be to customize a sleeve to allow the Ram Removable, 6" Poly Caster Assembly...

  • Is There a Wheel Caster that Can be Added to Round A-Frame Trailer Jack # TJA-5000S-B
    To add a wheel with the Round A-Frame Trailer Jack # TJA-5000S-B all you need is the wheel caster # JC-101. I would recommend supporting the tongue of the trailer with a floor jack before taking apart anything internal of the jack.

  • Will Replacing Jack Foot Plate With Caster Wheel Reduce Jack Weight Capacity or Trailer Capacity?
    You can replace your trailer's jack foot plate with a trailer caster wheel. Your tongue weight capacity will be the lowest of three numbers, 1.) the new caster wheel capacity, 2.) the old tongue jack capacity, or 3.)the trailers stated TONGUE weight capacity. For example, the etrailer # JC-101 caster has a stated capacity of 1200 pounds. This is for the wheel and caster assembly only. Even if your old trailer jack is rated for 2000 pounds, adding this caster reduces your capacity to 1200...

  • Can Caster Wheel Be Added to Jack with Footplate
    It would be possible to cut off the footplate on jack # TJP-2002S-B but doing so would of course void the item's warranty. Also, the drilling of the two holes needed to install a caster wheel like # JC-101 would possibly weaken that inner jack tube. The problem is you cannot know by how much you will have reduced the jack capacity by this modification. Also, the caster wheels available do not have the same 3000-lb weight rating that the original footplate does. So even if the jack tube...

  • Caster Wheel for Jack on 6 x 12 Enclosed Trailer
    You can add a caster wheel like # JC-101 to the Rack'Em B-52 Round A-Frame Trailer Jack # RA-29 but doing so will reduce the jack's tongue weight (TW) capacity because all caster wheels are rated for less weight than standard foot plates. The jack itself is rated for 5000-lbs but all caster wheels are rated for less weight, generally no more than 1200-lbs as with wheel # BD500245. If you have a tongue weight scale like # e99044 you can measure the loaded trailer to confirm what its actual...

    Fulton's Snap-Ring Swivel Jack # FTJ120W0301 fits on a snap ring mount with a pilot hole diameter of 2.313-inches. If this matches you're good to go. If not you might consider just installing a castor wheel on your existing jack. If you jack's inner tube has an outside diameter of 2-inches the you can use # JC-101 or # PS1400750340.

  • Wheel Caster Recommendation for a etrailer A-Frame Round Jack # TJA-5000S-B
    Yes, the correct wheel caster for the A-Frame Round Jack # TJA-5000S-B that you referenced is the Ram Removable, 6" Poly Caster Assembly for 2" Jack Tube # JC-101. Using this wheel will reduce the capacity of your jack from 5000 lbs to 1200 lbs. If this is a problem, you could instead use a footplate like the # JF-99. I attached an install video of these parts for you to check out.
