Thomas T Verified Purchase –
I needed an 8” center roller for an old 3 roller keel setup. It is only 7 1/2 “s but works out perfectly.

After a delayed delivery, I was pleased to receive the roller shaft set and had it successfully installed on my boat trailer in less than 30 minutes!

Does exactly what I need it to. With the larger self centering roller at the back of the trailer it makes mounting a snap

I installed this on my trailer this spring.
Unfortunately, because of the grade at my boat launch, this roller does not contact my keel until the boat is almost completely loaded.
I plan to adjust the trailer and maybe add a power winch.
When I do that maybe It will bring the roller more into play.
Good idea though.
