Extends the footrest and stirrup just the right amount to keep your heel away from the heatshield. I also used the Kuryakyn Longhorn brake pedal and Longhorn shifter peg. The combination makes for a more comfortable ride.
I needed peg extensions to get my size 12's away from the new chrome covers and exhaust. I went with the 1 1/4 in lieu of the 2 1/2 extensions as I did not want my boots sticking to far out. These extensions went right on as advertised but add another set of unsightly mounting hardware at the base of the pegs. Kuryakyn does make a set of real nice peg extenisons that does not require the added mounting hardware but they only work with Kuryakyn pegs. (Not HD pegs) Rode twice so far and these extensions seam to do the trick - I would buy again. As usual great service and price from Dennis Kirk.
