380lb rider on a 18 RG. I was just in the belief that a bagger and my size this is how they handle, front end would dive all the time in corners and breaking. I like to tide fast on the curves. Pete and the gang talked me into the front cartridges after I had already rode a year with his rears and let me tell you I was blown away. The difference they told me it would make is a understatement of the real difference and performance. Totally different ride!! It's worth every penny you will spend!
