This high-performance shock absorber offers a simple yet durable design that provides a cost-effective upgrade to your motorcycle's suspension system. Engineered for reliable performance, the 412 Series features a five-position cam-style spring preload adjuster, allowing riders to easily customize ride height and firmness to suit their riding style and load conditions. This adjustability ensures optimal comfort and handling whether you're cruising or tackling more demanding terrain.\u003cbr\u003eConstructed in the USA, the shocks are available with various style options, including full show-chrome or black covers, as well as chrome or black springs and end caps. Each shock is measured from center of eyelet to center of eyelet, ensuring compatibility and precise fitment. Please note that some shocks are approved for road use; refer to the latest certification for current listings. When installing on '86-'15 XL models, you may need to modify or space the chain or belt guard to achieve proper clearance. Additionally, selecting shocks that are slightly longer or shorter than stock can subtly alter the head angle, affecting steering response—longer shocks provide quicker steering, while shorter ones offer a more relaxed feel.\u003cbr\u003eHeavy-duty applications are recommended for bikes frequently operated at or near maximum load ratings, often over 50% of the time. Before purchasing or installing shocks that differ from OEM length, verify that your wheel travel can accommodate the change without contact issues with the swingarm, axle, exhaust, chain or belt guard, or tires. This ensures safe, reliable performance tailored to your riding needs and bike configuration, making the Progressive Suspension 412 Series Shock an excellent upgrade for improved handling and comfort.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley Dyna models from 1986 to 2015\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy customization\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with multiple style options including chrome and black finishes\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeasured from center-of-eyelet to center-of-eyelet for precise fitment\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for road use with current certification approval\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length options to modify steering response and handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty applications recommended for bikes frequently operated near maximum load\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with various style covers, springs, and end caps\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966963376325,"sku":"412-4038C","price":379.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160480.png?v=1773696508","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-12-5-inch-chrome-dyna-412-4038c","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
