I ordered them for a customer and then he cancelled the order. I thought I would offer them for sale to someone before I returned them. You are right tho' they are great shocks. I have them on my 03 FLHTC and couldn't believe how much better they are than the stock air shocks. Now when I go over big bumps or dips I dont have to cringe waiting for the bike to bottom out like I did with the stock air shocks.
The stock length is 13" but most people want to lower the bike at the same time. Getting the lowered shocks in the rear makes it a lot easier to back out of parking spaces and planting your feet at a stop light. I have my FLHTC lowered with these shocks. These shocks are way better than the stock shocks.
