This is a very nice riser and just bolted right in place. If you like to stand up while riding and your back hurts after you do it I recomend this product. It is a good price for this nice of a product. I was debating getting a 8in but i am glad i just got the 6in because it would be hard to drive sitting down.
I like it but I don't. The adapter that you have to buy with it is a joke....I didn't like how it fit together so I had to make a plate besides so it wouldn't come loose like it seems to do a lot. Maybe it is just my sled but just didn't like it. Go with a Fly or one of the other riser blocks with adapter
