Constructed with durability in mind, this shock features a simple yet robust design that provides a cost-effective improvement in suspension performance. Its black finish adds a sleek aesthetic to your motorcycle, making it suitable for various custom styles. The shock is manufactured in the USA, ensuring high-quality standards and longevity. Featuring a five-position cam-style spring preload adjuster, riders can easily fine-tune their suspension to match their riding preferences, whether carrying heavy loads or seeking a softer ride. The unit measures approximately 13 inches from center of eyelet to center of eyelet, aligning with OEM specifications to ensure proper fitment on Harley models from 1986 to 2015. When installing on certain models, such as XL variants, you may need to modify or space the chain or belt guard to prevent clearance issues. This shock can slightly alter the head angle if longer or shorter than stock, which may result in quicker or slower steering responses, respectively. Heavy-duty applications are recommended for bikes frequently operated near maximum load ratings, especially over 50% of the time. Before installation, it’s essential to verify that altering wheel travel won't cause interference with components like the swingarm, exhaust, chain or belt guard, or tires. Some options are approved for road use, so check the latest certification to ensure compliance. Available in various styles including chrome or black covers, and springs with matching end caps, this shock offers customization to match your bike's aesthetic. Overall, the Progressive Suspension 412 Series Shock provides a durable, adjustable, and visually appealing upgrade for Harley enthusiasts seeking improved suspension performance and ride comfort.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models from 1986 to 2015 for optimal fitment and performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster allows easy customization of ride stiffness.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with durable materials for long-lasting performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eStandard length of approximately 13 inches from center of eyelet to center of eyelet ensures compatibility with OEM specifications.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in various styles, including black, chrome covers, and matching springs and end caps for personalized aesthetics.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application recommended for bikes frequently operated near maximum load capacity.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eModifications to chain or belt guards may be necessary during installation on certain models.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjusting the shock length slightly longer or shorter can influence steering response by altering the head angle.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSome shocks are approved for road use; verify current certification for compliance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProper installation requires confirming wheel travel and clearance to prevent contact with exhaust, tires, or other components.\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031875387486,"sku":"13100709","price":345.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/159561.png?v=1784494230","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-412-series-shock-13-inch-black-for-harley-models-part-412-4065b","provider":"V-TwinVisionary","version":"1.0","type":"link"}
