Featuring a simple yet durable design, these shocks deliver enhanced ride quality and improved handling. The 12-inch length and heavy-duty construction make them an ideal choice for riders seeking increased durability and performance during demanding conditions. The black finish adds a sleek, understated look that complements the bike's aesthetic and resists corrosion for long-lasting performance. \u003cbr\u003e The 412 Series Shock includes a five-position cam-style spring preload adjuster, allowing riders to easily dial in their ride comfort and handling characteristics. Whether you're carrying heavy loads or seeking a smoother ride, this adjuster provides the flexibility to tailor suspension settings to your preference. These shocks are made in the USA, ensuring quality craftsmanship and adherence to strict manufacturing standards. \u003cbr\u003e Compatible with Harley models from 1986 to 2015, the shocks may require minor modifications, such as adjusting the chain or belt guard for proper clearance on certain bikes. Slight variations in length—either longer or shorter than stock—can influence steering characteristics, providing quicker or slower response as desired. It is essential to verify wheel travel and clearance to prevent contact with swingarm, exhaust, or tires when choosing shocks different from OEM length. Heavy-duty applications are recommended for bikes operated near maximum load capacity over 50% of the time, making these shocks suitable for demanding riding conditions. Overall, the Progressive Suspension 412 Series Shock is a cost-effective, high-performance upgrade that enhances riding comfort, control, and style for your Harley Dyna.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley Dyna models from 1986 to 2015\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e12-inch shock length with heavy-duty construction for durability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBlack finish for corrosion resistance and sleek appearance\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 strict manufacturing standards\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with various styling options, including chrome or black covers and springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCan be modified for proper clearance with chain\/belt guards and exhaust\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSlight length variations can influence steering response, either quicker or slower\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecommended for heavy-duty applications or bikes operated near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966961672389,"sku":"412-4036B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160502.png?v=1773696500","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-for-harley-dyna-12-inch-heavy-duty-black-part-no-412-4036b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
