Crafted with a focus on reliability, these shocks feature a robust design that provides a cost-effective solution for riders seeking improved ride quality and handling. The 13.5-inch length is designed to fit a variety of Harley FLH models, with a center-of-eyelet to center-of-eyelet measurement ensuring compatibility. Made in the USA, these shocks are built to meet the highest standards of quality and durability. \u003cbr\u003e The 412 Series shocks incorporate a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune their ride comfort and handling characteristics. Whether you prefer a softer or stiffer suspension setup, this feature provides versatile customization for different riding conditions and loads. The shocks are available with various styling options, including full show-chrome or black covers, along with chrome or black springs and end caps, enabling you to match your bike's aesthetic preferences. \u003cbr\u003e These shocks are suitable for heavy-duty applications, making them ideal for bikes operated at or near maximum load capacity over half the time. It's important to confirm that your wheel travel can accommodate shocks of different lengths without causing clearance issues with components such as the swingarm, axle, exhaust, chain or belt guard, or tires. When installing on '86-'15 XL models, some modifications or spacers may be necessary to ensure proper clearance. Slight variations in shock length can influence steering characteristics; a longer shock may quicken steering, while a shorter shock might result in slower handling. Proper installation and adjustment will optimize your bike's performance and safety. \u003cbr\u003e Whether you're upgrading for improved handling or customizing your Harley for personal style, the Progressive Suspension 412 Series shock offers a durable, adjustable, and visually appealing solution that enhances your riding experience.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley models, ensuring a proper fit and optimal performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy tuning of ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed with durable materials for long-lasting performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in multiple styles including full show-chrome or black covers, and chrome or black springs and end caps\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality manufacturing standards\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for heavy-duty applications, ideal for bikes operating near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCenter-to-center eyelet measurement for precise fitment\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility considerations include potential modifications on certain models for clearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length options to influence steering behavior and handling dynamics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProper installation may require checking wheel travel and clearance to components\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966981005509,"sku":"412-4078B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159900.png?v=1773697118","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-13-5-inch-heavy-duty-black-for-harley-flh-part-412-4078b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
