With a simple yet durable design, these shocks are built to withstand demanding riding conditions while providing a noticeable improvement in ride quality. The 11-inch length ensures compatibility with a range of Harley Dyna bikes, and the black finish adds a sleek, understated look to your motorcycle. Made in the USA, these shocks are a reliable choice for riders seeking performance and durability. \u003cbr\u003e The 412 Series features a five-position cam-style spring load preload adjuster, allowing you to easily dial in your preferred ride height and firmness. This adjustability ensures a customized riding experience, whether you're seeking a softer ride or firmer support for heavier loads. Some shocks in this series are approved for road use; please refer to the latest certification to confirm compliance. Additionally, multiple style options are available, including full show-chrome or black covers, as well as chrome or black springs and end caps, providing aesthetic flexibility. \u003cbr\u003e Installation considerations include potential modifications when fitting shocks on '86-'15 XL models, such as adjusting or spacing the chain or belt guard to maintain proper clearance. Slight length variations—either longer or shorter than stock—may influence steering characteristics by subtly altering the head angle, resulting in quicker or slower steering responses. For heavy-duty applications, these shocks are recommended for bikes operated near maximum load ratings over 50% of the time, ensuring they can handle demanding riding conditions. Before installing shocks that differ from the OEM length, verify that wheel travel and clearance are sufficient to prevent contact with the swingarm, exhaust, chain\/belt guard, or tires. This ensures optimal performance and safety during your rides.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley Dyna models, providing a tailored fit and optimal performance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy ride height and firmness customization.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA, ensuring quality craftsmanship and durability.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in various 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\u003eHeavy-duty applications recommended for bikes operated near maximum load ratings over 50% of the time.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility considerations include potential modifications for certain Harley models to ensure proper clearance.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSlight length variations may influence steering response by subtly altering the head angle.\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper wheel travel and clearance when installing shocks different from OEM specifications.\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":50007757127920,"sku":"DS310044","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/1980\/5424\/files\/160483.png?v=1783695084","url":"https:\/\/sublimepowersports.com\/products\/progressive-suspension-412-series-shock-11-inch-heavy-duty-black-for-harley-dyna-models-412-4045b","provider":"Sublime Powersports","version":"1.0","type":"link"}
