Video Transcript for etrailer Trailer Jack JC-102 Review

Today we're going to be taking a look at Removable Caster Wheel Assembly. This is going to provide light support and make it easier to move your trailer. Now, keep it mind that this does reduce the overall jack capacity to 1,200 pounds. The wheel is able to spin, so its got a nice rotating design. That's going to make moving your trailer much easier. It's going to come with the snapper pin, this is included for fast, easy, mounting and removal of the assembly to the jack.

The housing, so this area right here, this is going to be made from a steel construction. It's going to have a really nice clear zinc finish, so it's going to be a highly resistant for rust and corrosion. The wheel is going to be made from a durable steel construction. Nice solid design, the unit design for round jacks with an outer tube diameter of 2 1/4" and then the inner tube diameter needs to be 2". So we can tell that by taking a measurement from inside edge to inside edge, and that's where we're going to get the 2" measurement from. This will fit around trailer jacks that have an inner tube diameter of 2".

The pinhole, this right here, this is going to give us a diameter of 3/8". Then I also took a measurement from the very bottom, the bottom edge right here. The center of the pinhole, and I got a measurement of about 1". The diameter of the wheel is going to measure 5 3/4", and then the width of the wheel, we can get a good look at that as well. That's going to give us a measurement, that also be right around 1 11/16". Now, what i want to do real quick is I actually have a jack.

I want to go ahead and show you how to install. Very simple process, all we're going to need to do is take our jack, place the assembly over the inner tube. Line up the pinholes, and then secure the assembly on to the jack with that included pin. That's all there is to it. That's going to do it for today's look at the Removable Caster Wheel Assembly..

Once again e-trailer comes through with just what I needed. I needed a steel wheel for my travel trailer because the plastic one's broke. This is real beefy, and quality seems great, It cost a couple dollars more than the cheapo ones, but seems worth it. The shipping was good and fast. And customer service is unbeatable. Thanks Again Jack 282375

The JC-102 works perfect on my new aluminum trailer. Now I can move it with ease and no lifting the tongue up anymore! Rolls great in my gravel lot! 543229

Was delivered earlier than I thought it would This was a replacement of the original part ,but is built heavier than the original which is great. Ordered the pad and wheel adapters which work awesome. Have bought items from etrailer before and very satisfied with their service and product. 690560

Hitch delivered earlier than expected! Literally took 5 minutes to remove the old bent hitch and install the new one. 681874

Fits perfect. Only reason I did not give 5 stars, your stickers are placed poorly and do not come off easy. 627891

I purchased the etrailer JC-102 to use a new Wells Cargo Tandem trailer that it came originally with a landing pad, which made it difficult to move around by hand rolling. This 2 1/4" Trailer Jack Removable Steel Castor Wheel is well constructed and a great value. I highly recommend this wheel assembly! 611956

Quick delivery and the wheel fits the jack nicely. 381710

I bought the wheel for the new jack I bought from etrailer so I could pull it around the yard with the lawn tractor doing light yard work... gathering cut limbs etc. It works perfect for that. Not having to attach the truck to do yard work is great... and besides the truck cannot go under the trees whereas the lawn tractor can. I also bought the foot for using the truck. 379587

Loved the informitive video. The video helps to insure the correct part was purchased. The caster fits tight on the jack. 373183

  • Can Ultimate A-Frame Trailer Jack 322-RDJ-2K Be Completely Removed from Collar Assembly
  • Yes, the Ultimate A-Frame Trailer Jack # 322-RDJ-2K uses a separate trailer-mounted A-frame collar that allows complete removal of the jack tube from the collar. Please note that the jack ships with a black plastic wedge that is held in place with a small retaining bolt. If this bolt and wedge are removed from the jack then the entire jack can be lifted up and out of the collar to give you the clearance you need for opening the rear door on your Jeep. Please refer to the linked photo...

  • Size of Footplate or Caster With Wheel That Fits Ultimate Trailer Jack A-Frame Jack
  • You can add either a footplate or caster to the Ultimate Trailer Jack # 322-RDJ-2K. This jack has a 2-1/4" outer tube and 2" inner tube and the correct footplate is # JF-101BK while for a caster with wheel assembly # JC-102 is a fit and attaches to the inner jack tube. I've added links to video reviews of each of these parts for you to take a look at.

  • Trailer Jack that Doesnt Hang Down Very Far for a Big Tex Utility Trailer
  • Depending on the capacity you need I do have some A-Frame jack options you might like. Take a look at the Ultimate Trailer Jack # 322-RDJ-2K. It is more adjustable than other jacks and measures just 1-3/4" from the mounting bracket to the bottom of the leg with the jack fully retracted and the collar at the lowest setting. This jack is rated for 2,000 pounds. A wheel or foot will add more to that 1-3/4 inches so keep that in mind. For a wheel you can use # JC-102. For a foot you can...

  • Availability of Caster Wheel for Ram Trailer Jack
  • We do have a nice selection of jack wheels available, including a couple that are designed to work with Ram trailer jacks. I am not sure what particular model Ram jack you have, but you may be able to use the Removable 6 inch Caster # JC-102. This particular caster will attach to 2 inch diameter inner jack tubes and features a clear zinc finish on the bracket for corrosion resistance. Just note that this caster has a weight capacity of 1,200 pounds, so if you have a jack rated for a...

  • Mounting Plate Dimensions and Bolt Holes on Ultimate Trailer Jack # 322-RDJ-2K
  • I went out to our warehouse to measure the Ultimate Trailer Jack # 322-RDJ-2K for you. The bolt holes are oval slots each having a 3 inch on center measurement. They range from 2-5/8 to 3-5/8 inches from the front of the coupler back and then the side to side holes range between 2-3/8 inches to 3-7/8 inches. The overall plate dimensions are 4-7/8 inches on the back and 4-5/8 inches on the sides from the coupler back. I've attached a photo to assist. You may also be interested...

  • Ultimate Trailer Jack # 322-RDJ-2K Pin Function and Security
  • The Ultimate Trailer Jack # 322-RDJ-2K has the pin and holes in the outer tube assembly allowing the entire jack to be adjusted in 2 inch increments. The pin inserts the full 1/4 inch thickness of the outer tube and has a pin to keep the spring loaded pin mechanism from accidentally moving so you won't have the issue of trailer movement or a physical bump causing the jack to release under load. I've attached a video to further assist. This jack does not come with a footplate or wheel,...

  • Can Timbren Axle-Less Suspension System Work With Off-Road Tires?
  • There is a 2,000 lb capacity Timbren Axle-Less Suspension with 4" Drop Spindle # ASR2KHDS09, though not a 1,200 lb one. I am not certain what you are referring to in terms of "strong enough" but it will work with 3,500 lb rated hub and drum assemblies # 84546UC3-EZ as well as 3,500 lb brakes. If you were referring to your trailer being strong enough, if you do not have a crossmember above where you want to install the Timbren one will need to be added, or you can reinforce your trailer's...

  • Can Tube of Ultimate Trailer Jack 322-RDJ-2K Be Completely Removed
  • With the right tools and enough time a determined thief can steal almost anything. This is true for the inner tube of the Ultimate Trailer Jack # 322-RDJ-2K as well as the caster wheel # JC-102 or foot plate # JF-101BK that might be used with it. In order to remove the inner tube the black wedge shown in the linked photo would have to first be unbolted.

  • 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 # BDCP555. 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 A-Frame Trailer Jack for Applications with Limited Ground Clearance
  • For your a-frame trailer, I recommend using the Ultimate Trailer Jack part # 322-RDJ-2K which while in the retracted position will be completely flush to the frame and will not allow the jack from catching on uneven terrain while you tow. The jack has an extended length of 27-1/2" and 2,000 lb weight capacity. In order to add a caster wheel to this jack you will want to use part # JC-102. Please keep in mind that the castor wheel will reduce the capacity of the jack to 1,200 lbs while it...

  • Can Electric Jack be Submerged in Water
  • Electric jacks such as the Electric Jack w/ Footplate # EJ-3520-BBX should not be submerged in the water; they are resistant to rain but not being completely immersed under water. Instead you will want to go with a manual jack, such as the Ultimate Trailer Jack # 322-RDJ-2K which has a 2,000 lb capacity and 27-1/2 inches of lift. It would require either Footplate # JF-101BK or Wheel # JC-102. If you need more capacity but less lift there is the Bulldog # BD155032 which has a 5,000...

If you want a different jack that will have a compatible wheel, I recommend the Round A-Frame Trailer Jack - Topwind - 14-1/4" Travel - 2,000 lbs # TJA-2000-B along with the Removable 6" Caster for 2-1/4" Trailer Jacks - Steel Caster - 1,200 lbs # JC-102.

  • How to Determine if the Caster JC-102 Will Fit an A-Frame Jack
  • I don't have a way on my end to verify if the Removable 6" Caster for 2-1/4" Trailer Jacks # JC-102 will fit on your specific jack, as I couldn't find any information on it, but if you have a tape measure handy you can verify this on your end. If the outer diameter of your inner tube measures just under 2" and your pin hole diameter is at least 3/8" then then part # JC-102 will fit. I have attached a review video where you can see the measurement of the inner diameter of this caster...

  • What is Wheel of Removable 6" Caster # JC-102 Made Of
  • The wheel of the Removable 6" Caster # JC-102 that you referenced is steel. Nothing on the assembly is made of plastic actually. I attached a review video for this wheel for you to check out as well.
