700503 Brute Iii 1 Off Set Insert

Designed for custom Harley-Davidson drivetrain modifications, these Rivera Primo offset front pulley inserts allow for the installation of wider rear wheels by shifting the transmission alignment. This specific 2 1/2-inch diameter insert is compatible with Primo Brute III 1 3/4-inch and early Brute IV 3-inch belt drive pulleys. The precision-machined construction ensures the belt drive remains stable and aligned under load. Each unit comes as a kit including five countersunk screws and two dowel pins for assembly. Proper installation requires the selection of a matching outside guide, motor nut, and special washer. Rivera Primo provides the specialized hardware necessary for complex primary drive spacing and custom frame configurations.
