Progressive 412 Series shocks deliver a straightforward suspension upgrade with double-wall steel construction and nitrogen-charged damping tuned for consistent performance across light and heavy riders. Five-position preload adjustment lets you dial in comfort and handling without tools, while multiple spring rates and finish options fit most Harley cruisers.
Fits Harley-Davidson cruiser models. Verify your specific year and model on the Progressive website or contact customer service for exact fitment.
Yes — the five-position cam-style adjuster can be turned by hand to dial preload up or down for your weight and riding style.
Standard springs suit lighter riders; heavy-duty springs handle heavier loads and two-up riding without sagging. Choose based on your combined rider and cargo weight.
The nitrogen-charged damping and progressive valving smooth out bumps and reduce wallowing compared to worn stock shocks, improving both comfort and control.
The base shocks have a black finish. Show Chrome covers are optional on select applications — check fitment availability when ordering.
The double-wall steel construction and sealed nitrogen charge are designed for long-term durability. Service intervals depend on riding conditions and load.

The shocks seem super nice, but they are incredibly stiff. Turns out they’re 130/200 top to bottom. Would be nice to have an option to choose your spring rate. Couldn’t find it in the description either. Have them installed on a 1998 sportster 1200 by the way. I’m about 180lbs and they don’t move at all, my friend who weighs about 260 also said they were way to firm. Hope this helps.
