Featuring a 12-inch length, these shocks are designed to provide improved ride quality and handling while maintaining a cost-effective profile. Constructed with high-quality materials, they are suitable for heavy-duty applications, making them ideal for riders who operate their bikes at or near the maximum load capacity most of the time. The black finish adds a sleek, modern look to your motorcycle, complementing various styling preferences.\u003cbr\u003eEach shock includes a five-position cam-style spring preload adjuster, allowing you to easily fine-tune your ride for optimal comfort and handling. The adjustable preload provides versatility, whether you're riding solo or with a passenger and gear, ensuring a tailored suspension setup. Made in the USA, these shocks are compatible with a range of Harley models and are measured center-of-eyelet to center-of-eyelet for precise fitment. When installing on 1986-2015 XL models, some modifications or spacers to the chain or belt guard may be necessary to ensure proper clearance. Additionally, the length of the shocks can influence steering characteristics; a slightly longer shock can offer quicker steering, while a shorter one may slow steering for a more stable ride.\u003cbr\u003eIt is important to verify that your wheel travel and clearance are suitable before installing shocks that differ from the OEM length to avoid contact issues with the swingarm, exhaust, chain or belt guard, or tires. Some models may also be available with chrome or black covers, springs, and end caps for a customized appearance. These shocks are approved for road use, but it's recommended to consult the latest certification for compliance details. With their durable design and adjustable features, the Progressive Suspension 412 Series Shock provides a reliable, performance-oriented upgrade for Harley motorcycle enthusiasts seeking improved ride quality and handling.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models to improve suspension performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e12-inch length provides optimal ride height and handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty application suitable for maximum load conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for customizable ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with durable, high-quality materials\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSleek black finish enhances motorcycle aesthetics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with a range of Harley models, with potential minor modifications for 1986-2015 XL models\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length to influence steering characteristics—quicker or slower handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eApproved for road use with certification details available\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eOptional full chrome or black covers, springs, and end caps for style customization\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966857797829,"sku":"412-4050B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160859.png?v=1773695383","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-12-inch-heavy-duty-black-for-harley-davidson-models-part-no-412-4050b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
