If you are unsure of the diameter of the tubing on which you would like to install the highway pegs and do not have a dial caliper, or micrometer at your disposal, here is an easy way to figure it out. Use a crescent/adjustable wrench and lightly clamp it around the tubing, then carefully slide it off the tubing without loosening it up. Use a tape measure or ruler to measure the distance between the two jaws, and that is the diameter of your highway bar tubing.
Note: Large ISO pegs include clevis mount with 1 1/4 in. quick clamps and are not adjustable. For pegs with adjustable mounts, order the large ISO pegs with offset mounts, Part Number H49655
ATTENTION: It is the installers responsibility to ensure that all of the fasteners (including pre-assembled) are tightened before operation of the motorcycle. Kuryakyn will not warranty components lost due to improper installation. Periodic maintenance may be required.
