EZ SET 8 Degree Upper Mount only for most 4 Stroke Motors, Hardware"Our 8 degree 4 cycle EZ Set slider mount is the most rigid 4 cycle mount on the market and is highly recommended by Briggs and Stratton. Our 4 cycle mount has gone through many revisions over the years and our latest version is a streamlined design. We have added many more mounting holes which allows more offset, the ability to run the clutch inboard, and a bit lighter. Its sleek design and black anodize finish allow it to look good on any chassis."
