I purchased these because many of the launch ramps I use are so flat that I have to early totally bury my trailer tongue and float the boat to launch. I bought these as the pads set that I got at Cabela's did not have them included. I just got back from a trip to the coast fishing for salmon, also where I installed the complete set (Kit & BunkEnders). I was very happy with the way the boat slide onto the trailer. It was much easier to get on and latch on to my strap hook, and chain. I would highly recommend this system for all boaters. Thank you for providing the public with a very good product.
