Designed with simplicity and reliability in mind, these shocks are built to enhance ride quality and handling performance. Featuring a five-position cam-style spring preload adjuster, riders can easily fine-tune the suspension for varying loads and riding conditions, ensuring optimal comfort and stability on the road. Made in the USA, these shocks are available in a sleek black finish, with options for full show-chrome or black covers, as well as chrome or black springs and end caps, allowing customization to match your bike’s aesthetic.\u003c\/p\u003e\u003cp\u003eThese shocks are measured from center-of-eyelet to center-of-eyelet, making installation straightforward for compatible Harley models. When installing on '86-'15 XL models, some modifications or spacers may be necessary to ensure proper clearance with the chain or belt guard. Slight variations in length compared to stock shocks can subtly influence the head angle, offering either quicker or slower steering characteristics depending on the adjustment. For heavy-duty applications or bikes operated near maximum load ratings over 50% of the time, these shocks are recommended to provide additional durability and support.\u003c\/p\u003e\u003cp\u003eBefore selecting shocks that differ from the OEM length, it’s important to verify that your wheel travel and clearance space prevent contact with components such as the exhaust, swingarm, chain\/belt guard, or tire. Some or all of the shocks listed are approved for road use; always refer to the latest certification for compliance. Whether you seek improved ride comfort, handling, or customization, the Progressive Suspension 412 Series Shock offers a reliable upgrade to enhance your Harley-Davidson experience.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson FLH models for optimal fit and 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 black finish with options for chrome covers and springs\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 for straightforward installation\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966973829317,"sku":"412-4073B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159897.png?v=1773696663","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-for-harley-flh-13-5-inch-black","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
