Video Transcript for Dutton-Lainson Boat Trailer Parts DL21562 Review

Today were going to review part number DL21562. This is the Dutton Lainson boat trailer rocker roller. This is a four and a quarter inch wide wobble roller thatll replace one of the worn out rollers on your boat trailers roller bunk. I9t is constructed of a heavy duty rubber construction which will deliver sturdy support. It replaces one wobble or rocker roller on the bunk assembly of your boat trailer. This part is made in the USA.

A few dimensions on this the width is four and one quarter inches. The diameter is also four and a quarter inches. The hull size in the middle there is three quarters of an inch so this application will fit on a roller bunk with a three quarter inch diameter shaft. That should do it for review on part number DL21562.

Boat trailer rocker rollers.


After 1 year they still function properly . My boat is constantly on and off the trailer , however 1 roller has cracked .

For the price they are worth it , but could be better


Found these exact replacements for a 30 year old trailer and had them in my hand in three days! Great service and fast delivery is all I could ask for!
Thanks Guys!

These rollers have worked great and are still in as good shape as when I received them. Fact is, someone else liked them and took one off my trailer while parked at the loading ramp. I had another one from you guys in less than a week again. Thanks for the great service!

Four of the rollers on my boat trailer were in bad shape. The on-line description of etrailer's rollers was so complete that it was easy to find the exact replacement. I also ordered a bow guard that fit perfectly. This was my second order with and I won't hesitate to buy more from them.


Arrived early and was exactly as described. Little pricey after shipping though. Ordered more with another item that put it in the free shipping range which made them a great deal.

Havent used as much as Id like but still holding up well.

Roller worked perfectly on my boat trailer. Still great after a year. Good quality and easy to attach.


Exact replacement for what I have . Easy to change out. I did it at the public dock with the boat in the water and my three year old running around . I be ordering more as the old ones give out .


This is a nice product which was delivered in good condition and on time by e-trailers. Very satisfied!

  • Bearing Length on the Ribbed Rocker Roller Boat Trailer Roller

  • 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.

  • Installing/Replacing # DL21562 Rocker Roller On A Boat Trailer
    Not at all, the procedure is really very simple. You'd use pliers to remove the existing Hog or Retainer Ring, remove the old washer (if present) and remove the existing roller. Install the new roller, replace the # CE10983 washer and install a new # CE10981 retaining ring by slipping it over the shaft and crimping it with pliers. This roller is designed to work on a 3/4 inch diameter shaft.
