In order to find the correct ribbed rollers for your boat trailer, you will need to measure the diameter of the shaft on the roller bunk assembly. For example, the CE Smith Ribbed Wobble Rollers # CE29210 fit both 3/4" and 1-1/8" roller shafts due to their removable bushings. These rollers are 5" diameter x 3" wide.

Another example would be the Yates Ribbed Wobble Roller # YR500YW-8P which is for rollers bunks with a 1" diameter shaft. This roller is also 5" diameter x 3" wide.

I've added links to video reviews of these rollers for you, as well as a link to our page with each of our ribbed rollers.
