412-4084B PS, 412 series shock set. 13.5". Heavy Duty. Black

For Dyna riders who often carry a passenger or heavy gear, these Progressive Suspension 412 series heavy-duty shocks are the way to go. Designed to fit 1991 to 2017 Dyna models, excluding the 2012 to 2016 FLD Switchback, these 13.5-inch black shocks feature a nitrogen-charged double steel wall body. The heavy-duty springs are specifically recommended if you operate at or near the maximum load rating more than half the time. They include multi-staged velocity-sensitive valving and a five-position cam-style preload adjuster to handle the extra weight. Sold as a pair, these shocks provide the support needed for big miles with a full load without bottoming out, ensuring a stable and comfortable ride on your Big Twin.
