Our folding foot pegs fit our mounts and also traditional factory Harley mounts that use a "D" spring washer. These folding foot pegs attach with a 5/16'' bolt. They are 1-1/4'' diameter and about 5'' long from the pivot hole to the end. These folding foot pegs are machined from solid 360 Brass. For those that prefer the brass look, feel free to check out our selection and let us know if there's a part you'd like to see featured in Brass.
