Constructed with a simple yet durable design, these shocks are suitable for riders seeking enhanced ride quality and reliability. The 412 series features a five-position cam-style spring preload adjuster, allowing you to easily dial in your ride for a more comfortable and controlled experience. These shocks are made in the USA and are available in multiple style options, including full show-chrome or black covers, as well as chrome or black springs and end caps, providing customization to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment for compatible Harley models. When installing on '86-'15 XL models, some modifications or spacing of the chain or belt guard may be necessary to ensure proper clearance. A slightly longer shock than stock can alter the head angle slightly, resulting in quicker steering, while a shorter shock may produce slightly slower steering characteristics. Heavy-duty applications are recommended for bikes operated at or near the maximum load rating over 50% of the time, ensuring durability under demanding conditions. Before purchasing or installing shocks that differ from the OEM length, verify that your wheel travel can be safely altered without causing clearance issues such as swingarm or axle contact with exhaust components, chain or belt guards, or tires. These shocks are designed to provide a reliable, adjustable suspension upgrade that enhances handling and ride comfort for Harley motorcycle enthusiasts.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley models to improve suspension performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy ride customization.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in multiple style options including show-chrome or black finishes.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with durable construction for long-lasting performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCenter-to-center eyelet measurement ensures proper fitment.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for '86-'15 XL models with possible minor modifications required.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAllows for subtle changes in steering response with length variations.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty applications recommended for bikes under high load conditions.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eVerify wheel travel compatibility before installation to avoid clearance issues.\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966986674373,"sku":"412-4066B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159239.png?v=1773697660","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-11-5-inch-heavy-duty-black-part-number-412-4066b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
