With a durable and simple design, these shocks enhance ride comfort and handling performance. The 13-inch length provides a balanced stance, improving overall stability and control. Made in the USA, these shocks feature a black finish that complements various Harley-Davidson styles and customizations. They are constructed with high-quality materials to ensure longevity and consistent performance under a range of riding conditions. \u003cbr\u003e \u003cbr\u003e The 412 Series shocks include a five-position cam-style spring preload adjuster, allowing riders to easily customize ride height and firmness to suit their preferences or riding conditions. This adjustability means you can dial in your suspension for a softer ride on rough roads or a firmer feel for spirited riding. Some shocks in this series are approved for road use, but it is advisable to refer to the most recent certification for current compliance. Multiple style options are available, including full show-chrome or black covers, along with chrome or black springs and end caps, providing aesthetic versatility to match your motorcycle’s look. \u003cbr\u003e \u003cbr\u003e When installing these shocks on Harley-Davidson models from 1986 to 2015, you may need to modify or space the chain or belt guard to ensure proper clearance. Slight variations in shock length—either longer or shorter than stock—can subtly alter the head angle, affecting steering responsiveness. Heavier duty applications are recommended for bikes frequently operated at or near maximum load ratings, typically over 50%. Before choosing shocks that differ from the OEM length, confirm that wheel travel and clearance are sufficient to prevent contact with components such as the swingarm, exhaust, or tires. Proper installation and adjustment will help you achieve optimal ride quality and handling performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models, ensuring a precise fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e13-inch length offers a balanced stance for improved stability and handling\u003c\/li\u003e\u003c\/ul\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\u003eMade in the USA with high-quality materials for durability and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in multiple styles including full show-chrome or black covers, chrome or black springs and end caps\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with a wide range of Harley models from 1986 to 2015, with potential modifications needed for installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAllows for fine-tuning steering response by selecting shocks longer or shorter than stock\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty applications recommended for bikes frequently carrying maximum loads\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper clearance and wheel travel before installation to prevent component contact\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSome shocks are approved for road use; refer to current certifications for compliance\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966860222661,"sku":"412-4002B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160804.png?v=1773695510","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-13-inch-black-for-harley-davidson-part-412-4002b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
