Progressive 412 Series Shocks 13″ Standard, Big Twin And 77-03 Sportster

Progressive Suspension 412-series shocks for Harley-Davidson Sportster and FXR (13-inch/heavy duty/black)

Progressive’s 412 Series shocks are the “bang-for-the-buck” standout in Progressive’s catalog—but “value” doesn’t mean “budget” here. A vast improvement over sacked (or even new) stock suspension, the 412 rides nicer and will up your cornering abilities noticeably. Double-wall steel bodies are nitrogen charged, and velocity-sensitive valving handles damping duties worlds better than your OEM shocks could even dream of doing. The five position cam-style preload adjuster allows you to make arguably the most important setup adjustment possible: sag. Grab a set of 412’s for your bike today and see what you’ve been missing with those sad factory marshmallows.
