4-1/4" Wide wobble roller replaces 1 worn-out roller on your boat trailer's roller bunk. Heavy-duty rubber construction delivers sturdy support.


I am restoring a 1993 VM trailer that came with a Sanger DXII I recently purchased. I needed to replace the trailer rollers, and found your site had the same exact part that was used by VM originally. I order them and they were delivered in one day.
Great availability, price, and service. Thumbs UP!

Fine, except I think if the rollers were made of a different material, they wouldnt leave marks on the hull.


Got your email before I opened the box. Just came today.Sooner than expected. They are the absolute finest black rollers I have ever owned. Match old ones perfectly.
If I could only figure out how to fit them on my '65 Scout.


Great product good price


The parts are great, just what I was looking for and the shipping was quick


After a year on the trailer the roller looks like brand new. No problems so far.


4 1/4 inches rubber wobble wheels. Easy to change. I cant wait to put my boat on them. Excellent product


I received exactly what I a timely manner also. I am very glad I ordered from etrailer where I was shown the shipping cost before I committed to the sale. Which is not what ezloader does...they don't even show you the shipping cost on the final bill...I will definitely order again for etrailer....Thank you so much....

Steve H.


Soon after I installed the rollers, I sold the trailer. But your product matched the rollers I had on the trailer and was an perfect match to my original rollers. Thank you for the excellent service and product.


I got it only for an year but so far work as a charm.


These rollers were a perfect replacement for my 1994 originals. Way better than others I found.





Very well very pleased thank you


High quality part. E-trailer is the best source for parts


these are going on a boat trailer of 4000 lbs,hopefully they will last as long as my others of the same roller,i got the yates washers along with them....the install was very easy,i also used s.s. cotters pins,great shipping also....thanks for all the i need (30) more


While I have not mounted these yet, I find them to be durable, of very quality. I was pretty much guessing about the size when I ordered them but they are appear to be spot on. The entire transaction, and pricing was great. I just bought set of lights too since this order went so well.

Pictures will follow when I mount these!


I placed my order Monday afternoon, it shipped from the Midwest and arrived here in Va on Wednesday, outstanding! Teresa J was very helpful in getting my order placed. The ratchet straps are great quality but too big for my trailer so I needed to send them back. She was awesome in helping me with that process, it couldn’t have been any easier. This is my second time ordering from this company and won’t be the last, fantastic customer service!!



I have purchased the wobble rollers YR440R as a direct replacement to the existing rollers due to weather age andgeneral wear. The service was very promped and detailed information so that you will get your purchase at a reasonable time, they also follow up after delivery. I Highly Recommend this Company.


These guys are Johnny Lightning ordered Wednesday and delivered Saturday morning. Installed on the trailer 15 minutes later. BUT After installing the new roller I came to the conclusion I should have ordered the full set of 10. Well no worries these guys are great to deal with.


Carry a lot of products and we got just what we needed. Have dealt with
previously and continue to have good transactions. Reasonable prices and very
fast shipping. Will continue to shop with them for our trailer needs.


Old trailers are hard to find parts. I could not find the part in the Twin Cities. I found etrailer on-line and took a chance. This was a 100% match. The part installed and works perfectly.


Great winch. Bolted right on my 1985 Shorelander trailer with no modification. It has been on my trailer for one year outside in all Ohio weather and still looks and operates like brand new.


Excellent, the wobble rollers, & so is your shipping. Rollers goes on my boat trailer & I will be ordering in the near future. Thanks a heap


The rollers are exactly what I needed. I have an older trailer and these are hard to find.They are are of excellent quality. The only down side to my order was the clips I ordered. They are very difficult to install. I do not know if there is a special tool needed.


I am very happy with the rollers for my boat trailer. They arrived when they were supposed to and fit beautifully. They were exactly what they were advertised to be. Thank you.


Item as described and well made, could'nt of picked a better company to buy these from. Fastest shipping I have ever received on the net. etrailer will be getting all my trailer needs from now on. And I'm letting my friends know about there great service before and after the sale. Keep up the good work!


Ordered 2 of these to replaces the ones on my trailer. They were perfect!! Exact match and took 10min to change. Shipping was awesome !! Showed up a day early even !! Would not hesitate to buy from this site again!!

Great job trailers !!!

  • Does Yates Wobble Roller part # YR440R have a Metal Bushing
    The Yates Wobble Roller part # YR440R does not have a metal bushing.

  • Can a Ribbed Wobble Roller be Used in Place of a Regular Wobble Roller on a Boat Trailer
    The Yates Ribbed Wobble Roller, # YR343R-6P, is 3 inches wide when compared to # YR440R which is 4-1/4 inches wide. If the 3 inch width will still work for your application then you can use it in place of the # YR440R roller.

  • Inner Width of Yates Ribbed Wobble Roller - Heavy-Duty Rubber - 5" Diameter - 3/4" Shaft
    I went out to the warehouse and measured Yates wobble roller # YR530R-6P. The width of the center is 1-5/8 inches so it will be too large. Your best option is going to be roller # YR440R which is much narrower but the overall width is 4-1/4 inches. The diameter is also 4-1/4 inches. I have linked a video review for you.

  • Troubleshooting Wobble Roller Rollers Not Rolling
    In order to get your wobble rollers rolling again I have two recommendations. The first is to attempt to pull them off and clean them, then use grease to free up the movement. Another possibility is that the shaft is bent. You should be able to bend it back if you find this to be true. If this does not solve the problem you will want to replace them. In order to find a replacement roller you will need to know the diameter of the shaft to make sure it fits. I would also recommend measuring...

  • What Holds Wobble Rollers onto a Trailer
    The Yates Wobble Roller # YR440R that you referenced should work well for you since it has the same 3/4 inch shaft as your trailer. Wobble rollers are held on with retainer rings like the CE Smith Wobble Roller Retainer Ring # CE10981. Basically, you put the open end of the retainer ring around the shaft on each end of the roller then use some pliers to clamp it closed so it is tight to the shaft. This allows the roller to roll but stay in position. Basically, the ring has to gently but...

  • Recommended Replacement Boat Trailer Roller with Wobble Function
    The Yates Ribbed Wobble Roller # YR500YW-6P has a bushings that measures 3/4" inner diameter the whole way through so it will reflect the angle of the shaft you're needing to install it on, so it will work great for your application as long as the rollers are at the correct angle for your boat. The term "wobble" is more or less a generic term for a roller used to load boats on a trailer and it unfortunately doesn't mean that ever roller has that "wobble" movement. If you really need the...

  • Does The Yates Wobble Roller # YR440R Use Any Type Of Bushing?
    The Yates Wobble Roller # YR440R are black molded rubber with a chemically bonded zinc-chromate washer rather than a bushing. This allows the roller to pivot as well as roll. If you prefer to not have the excess movement you should consider replacing all your rollers with the Yates # YR500YW-6P

  • Will New Wobble Rollers Leave Black Marks on Boat Hull
    The Yates Wobble Roller # YR440R will leave black marks but you can use the yellow version # YR500YW-6P instead to avoid marking up your boat. I confirmed this with my contact at Yates. This has a slightly larger diameter at 5" as opposed to the 4-1/4" but it will work just the same.

  • Replacement Boat Trailer Rollers That Fit 3/4" Shaft
    We have a few options for replacement rollers that fit 3/4" roller shafts. The Yates Ribbed Wobble Roller # YR530R-6P is 3" wide, 5" in diameter, and fits 3/4" shafts. The Yates Ribbed Wobble Roller # YR343R-6P is also 3" wide and fits 3/4" shafts, but has a diameter of 4-3/8". These two roller options made of heavy duty rubber and are considered ribbed design, which provides excellent traction for slimy hulls. Another option is the Yates Wobble Roller # YR440R. This measures 4-1/4" wide,...

  • Washer and Pin to Use with the CE Smith Wobble Roller YR440R
    For washers to go with the part # YR440R we have the part # CE10983. Wobble rollers are held on with retainer rings like the CE Smith Wobble Roller Retainer Ring # CE10981. This gets clamped so that the holes on your shaft get pinned by the ring.

  • Difference Between Rocker-Rollers and Wobble Rollers for Boat Trailer
    At one time, wobble roller was a patented term, but now the term wobble roller and rocker-roller are interchangeable. The # DL21564 roller you mentioned has an integrated bushing that makes the roller track straight on the shaft it's installed on, while the other two rollers lack this bushing. Not only would these rollers be capable of rotating on the shaft, they'd also wobble as well. The key would be to determine which style your boat trailer uses and use the appropriate replacement.
