Replacement 4-1/2 Inch Long Spool Rollers for a Boat Trailer  

Question:

Helpful Expert Reply:

In order to find the correct replacement spool roller for your boat trailer, you would need to measure from the inside of each mounting bracket. The 4-1/2" long measurement that you provided is not common and we would not have anything that matches this dimension exactly.

With that being said, I recommend using a 4" long roller and adding a couple washers on each side. You could also tighten the brackets more to pull them in further. The bells that you mentioned would be too thick to close the 1/4" gap you would have on each side.

If you have a 1/2" roller shaft then you would want to use part # YR4163-4P or part # YR4163-5 if you have a 5/8" roller shaft. If you would also like to replace the roller shaft you can use part # CE10700A for 1/2" or part # CE10721A for 5/8".

I measured my spool rollers inside the brackets at 4 1/2 can I replace with 3 rollers and add bells to the ends to achieve the 4 1/2. or would I be better off putting 4 rollers with washers to take up the slop?

Since we do not have a 4-1/2" long spool roller, I recommend using a 4" long spool roller like part # YR4163-4P for 1/2" shafts or part # YR4163-5 for 5/8" shafts and adding a washers to take up the extra space. Using a smaller 3" spool roller and bells would not be recommended as the surface area and capacity would not be suited for the hull of your boat.
