PROGRESSIVE SUSPENSION 412 Series Shock - 13" - Standard - Black - FXD 412-4083B

Stock shocks on your FXD limit both comfort and handling precision—especially under load or aggressive riding. The Progressive 412 Series delivers a measurable upgrade with adjustable preload tuning and durable construction designed specifically for Harley dynamics. At this price point, you're getting suspension geometry control that typically costs significantly more.

The five-position cam-style preload adjuster lets you dial in spring load without tools or disassembly, adapting to riding conditions, passenger weight, or luggage in minutes. Built on Progressive's proven platform, these shocks handle the demands of daily riding and weekend miles with equal competence.
