This shock absorber features a five-position cam-style spring preload adjuster, allowing riders to easily dial in their preferred ride height and firmness for optimal comfort and handling. Whether you're looking for a smoother commute or improved handling during aggressive riding, this shock provides versatile adjustability to meet your needs. Made in the USA, the 412 Series Shock is built with quality materials that ensure long-lasting performance and reliability. It is available in multiple styles, including full show-chrome or black covers, along with chrome or black springs and end caps, enabling you to customize the look of your motorcycle while benefiting from improved suspension. Each shock is measured from center of eyelet to center of eyelet, ensuring proper fitment for your Harley FXD models. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard for proper clearance, especially if choosing shocks that are slightly longer or shorter than stock. Slight variations in shock length can influence the head angle, resulting in quicker or slower steering responses, which can be advantageous based on your riding style. Heavy-duty applications are recommended for bikes operated at or near the maximum load rating over half the time, providing extra durability for demanding riding conditions. Before selecting shocks that differ from OEM length, verify that wheel travel and clearance around the swingarm, axle, exhaust, and chain or belt guard are maintained to prevent contact issues. This shock is an excellent upgrade for riders seeking a cost-effective, reliable suspension improvement that enhances ride quality and handling on Harley FXD models.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for customizable ride height and firmness\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy duty construction designed for demanding riding conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMultiple styling options including chrome or black covers and springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality materials for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCenter-to-center eyelet measurement ensures proper fitment for Harley FXD models\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length options to influence steering response and handling\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966974156997,"sku":"412-4084B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/689563.png?v=1773696715","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-13-inch-heavy-duty-black-for-harley-fxd-412-4084b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
