Crafted to enhance ride quality and handling, this shock features a five-position cam-style spring preload adjuster that allows riders to fine-tune their suspension settings easily for a personalized riding experience. Constructed in the USA, these shocks are built with quality materials and are suitable for a variety of Harley models, providing a cost-effective solution to improve comfort and stability. Please note that some shocks listed are approved for road use; always consult the latest certification to confirm compliance.\u003cbr\u003eThe 412 Series Shock is available in multiple styles, including full show-chrome or black covers, with options for chrome or black springs and end caps, enabling you to customize the appearance of your bike. When installed on '86-'15 XL models, modifications such as spacing the chain or belt guard might be necessary to ensure proper clearance, especially when using shocks that are slightly longer or shorter than stock. An adjustable shock length can subtly influence head angle and steering response: longer shocks may lead to slightly quicker steering, while shorter shocks can result in slightly slower handling. These shocks are measured from center of eyelet to center of eyelet, providing consistency across installations.\u003cbr\u003eHeavy-duty applications are recommended for bikes frequently operated near or at the maximum load capacity, ensuring durability and performance under demanding conditions. Prior to purchasing or installing shocks that differ from OEM length, verify that wheel travel and clearance are sufficient to prevent contact with components such as the swingarm, exhaust, or tires. Proper installation and compatibility checks will help maintain optimal motorcycle handling and safety, making the Progressive Suspension 412 Series Shock a reliable upgrade for riders seeking improved ride quality and adjustability.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models, ensuring precise fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy suspension tuning\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality materials for durability and reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in multiple styles, including full show-chrome or black covers, with chrome or black springs and end caps\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeasured from center-of-eyelet to center-of-eyelet for consistent installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for heavy-duty applications, ideal for bikes operated near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility considerations include potential modifications for models '86-'15 XL and length adjustments affecting steering\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsures proper clearance from components like chain\/belt guard, exhaust, and tires\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966860419269,"sku":"412-4001B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160797.png?v=1773695518","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-for-harley-davidson-12-5-inch-standard-black-part-412-4001b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
