I have a torn front outer cv boot so I ordered a new one off motorcycle superstore. Went to replace it and before I was ready to take the old boot off I realized that the larger diameter hole looked smaller then the stock boot. I then took a piece of weed eater string (at camp and all I had) to try and get a rough measurement of the stock boot and the stock boot is about 1 in bigger in diameter then the new replacement. Do these boots stretch out a lot? Should I worry about it being to small?

I also double checked to make sure it’s the right one and the part #’s match up from the website and on the box.
