Its design focuses on providing a cost-effective way to enhance ride quality while maintaining reliability. The shock features a five-position cam-style spring preload adjuster, allowing you to easily customize the ride stiffness to suit your riding style and load conditions, ensuring optimal comfort and handling. Made in the USA, this shock is designed with quality materials that withstand the rigors of road use and provide long-lasting performance.\u003cbr\u003eMany shocks in the 412 Series lineup, including this model, are approved for street use. However, it is recommended to consult the latest certification to confirm compliance with local regulations. The available style options include full show-chrome or black covers, with either chrome or black springs and end caps, allowing you to match your bike's aesthetic preferences. When installing on Harley-Davidson models from 1986 to 2015 XL series, some modifications or spacers may be necessary to accommodate chain or belt guards for proper clearance. The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring precise fitment.\u003cbr\u003eDepending on the length chosen, these shocks can slightly alter your motorcycle’s head angle, resulting in quicker or slower steering response. Opting for a slightly longer shock can provide more stability and slightly quicker steering, while a shorter shock may offer a more relaxed steering feel. Heavy-duty applications are recommended for bikes frequently operated near their maximum load capacity over 50% of the time. Before installing shocks that differ from OEM length, verify that your wheel travel can be adjusted without causing clearance issues with the swingarm, axle, exhaust, or tire, to ensure safe and optimal operation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models for a perfect fit\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\u003eMade in the USA with durable, high-quality materials\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMultiple style options including chrome or black covers and springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for street use with approved certification (refer to latest certificate)\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCenter-to-center eyelet measurement ensures precise installation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length can influence steering response and handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRecommended for heavy-duty applications when operating near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires potential modifications on certain Harley models for proper clearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed for reliable performance and long-lasting durability\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966860026053,"sku":"412-4003B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160808.png?v=1773695483","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-for-harley-davidson-13-5-inch-black-part-no-412-4003b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
