## Customer Reviews

### ⭐⭐⭐⭐⭐ Fit very well
*by O***L on July 7, 2025*

Why did you pick this product vs others?:Total install in 1 box

### ⭐⭐⭐⭐⭐ Complete kit which makes life much simpler
*by A***R on February 4, 2025*

We boat in salt water and rinse down the trailer after each use. We also have a fresh water flush into the drums. Time will tell as to how long this kit lasts but it comes with everything you need. Nothing more to say because if you know what you are doing, that is all that matters, having all the needed items.

### ⭐⭐⭐⭐⭐ That the backing plate and the drums were the right size
*by D***A on June 19, 2024*

I like that everything that was in the picture, was included in the purchase 👍🏼
