Designed with simplicity and durability in mind, these shocks provide improved ride comfort and handling by effectively absorbing road irregularities. The 412 series features a five-position cam-style spring preload adjuster, allowing riders to easily fine-tune suspension stiffness for varying riding conditions and loads, ensuring a personalized and comfortable ride experience. \u003cbr\u003eMade in the USA, the shocks are available in various styles, including full show-chrome or black covers, with either chrome or black springs and end caps, enabling customization to match your bike's aesthetic. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment and compatibility with your Harley. When installing these shocks on '86-'15 XL models, some modification or spacing of the chain or belt guard may be necessary to achieve proper clearance and avoid contact issues. \u003cbr\u003eThese shocks are designed to slightly alter the head angle depending on their length compared to stock, which can result in quicker or slower steering response—longer shocks tend to provide quicker steering while shorter shocks may slow down steering response. Heavy-duty applications are recommended for bikes frequently operated near the maximum weight capacity, especially over 50% of the time, to ensure durability and performance under stress. Before replacing OEM shocks with different lengths, confirm that wheel travel and clearance around swingarm, axle, exhaust, and tire are adequate to prevent contact issues. Overall, the Progressive Suspension 412 Series Shock is a versatile and durable upgrade that enhances ride quality for Harley-Davidson enthusiasts seeking improved suspension performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models for perfect fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for easy customization\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with durable materials for long-lasting reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in various styles including chrome or black covers with matching springs and end caps\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeasures from center-of-eyelet to center-of-eyelet for precise fitment\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for heavy-duty applications when operating near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with Harley XL models from 1986 to 2015, with possible minor modifications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAlters steering response slightly depending on length relative to stock shocks\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper clearance around swingarm, axle, exhaust, and tire before installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProvides an affordable upgrade to improve motorcycle handling and comfort\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966985625797,"sku":"412-4075B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159305.png?v=1773697527","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-11-5-inch-heavy-duty-black-for-harley-fl-models-part-412-4075b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
