          Rated 3 out of 5 by from good shock for single rider not 2 up The shocks work ok but the springs could be a bit stronger since I got the heavy duty model . I was expecting a bit stronger spring , 2 up riding they just don't seem to have the strength to stop bottoming out even when adjusted to the 5th (highest)setting , one up no problem but if your riding 2 up a lot don't use these .

          Rated 5 out of 5 by from Equivalent to OEM Purchased a set to replace the stock shocks on my 2005 Vulcan 1600 Classic, because the air bag on of them had blown. The replacement cast of the OEM was up around $560USD, so I took a chance on these. I also replaced the tires at the same time- original rear was bridgestone 170/70/16 and I replaced it with shinko 170/80/16. The next day, I went on a 3-day 1700 km road trip. I didn't notice much of a difference in ride comfort, but the handling seemed much improved- more nimble.

          Will going from 13 to 11.5 on a 2003 road king require any adjustment to the bags or the drive belt Bags are hard leather covered

          Asked by: STUMP
          With there being barely 1.5", we don't think that any adjustments would be necessary. However, the bags should be easy to tighten if you do have to adjust them.

          What's the difference between the standard and the heavy duty?

          Asked by: Katomia
          The key difference is the spring rate of the heavy duty being heavier. Heavy Duty Applications are recommended for bikes that are operated at or near the manufacturer’s maximum load rating over 50% of the time
