These cage mounts are designed to fit on the factory cage right above the shock reservoir. Simply remove the two bolts holding the two pieces of the factory cage together and insert this mount on the inside of the cage. This mount will give you adjustability to change the angle of the whip, so you could have it straight vertical or angle it back slightly if that is the look you prefer. These amounts are sold as a pair.
