These were on my bike, for what I am told, about 2 years / 3500 miles. I decided to go with 12" units, to lower my bike in the rear, because I went with a 21" front wheel. I like the rake it now has.
The full part number is shown, 444-4002, and they are 13" eye to eye. The springs are I-15316-1367-30, and are a very nice ride indeed. The left side shock has some chrome blasting, likely due to the belt and pulley, because the bike had been modded, and the belt cover was missing, causing some extra pitting on the lower end of the spring. They are not perfectly new, but look very good installed. I also have 4 thick washers, just not shown. I have nothing else for them, no tool, no papers, no original box, etc... I will do $350.00 shipped to your door. Please PM for PayPal email.

I just realized these will fit comfortably in a medium flat rate priority box, so I am dropping the price to $320.00 shipped and insured. Thx.

Good deal here

Really?!?!

Are these standard or heavy duty springs?

According to the Progressive website, the 4002C units are standard duty. As for the springs, I assume they are made for the shock part number, so I guess standard duty. I listed the spring number, I-15316-1367-30, and as far as I can find online, that is what I can determine. These were on the bike when I bought it, and rode great, I just wanted to lower it, so I went with 12" units. Thanks.

OK, Cool!
