PROGRESSIVE SUSPENSION 412 Series Shock - 13" - Heavy Duty - Black - FXD 412-4084B

If your FXD regularly carries near-maximum load or sees consistent heavy use, the stock suspension geometry simply won't cut it. Progressive's 412 Series shocks are purpose-built for these demanding conditions, delivering the durability and adjustability you need without the premium price tag of premium suspensions. The five-position preload adjuster lets you fine-tune your ride characteristics on the fly—no tools required.
