Designed for riders seeking improved ride quality and enhanced handling, this shock features a five-position cam-style spring preload adjuster that allows you to easily customize the ride to your preferences. Its robust construction ensures longevity and reliable performance, making it a cost-effective solution for riders demanding durability and versatility.\u003cbr\u003eMade in the USA, the 412 Series Shock is available with various styling options, including full show-chrome or black covers, along with chrome or black springs and end caps. This adaptability allows you to match the shock to your bike's aesthetic while enjoying the benefits of improved suspension. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring accurate fitment and installation.\u003cbr\u003eWhen installing these shocks on Harley models from 1986 to 2015, some modifications may be necessary, such as adjusting or spacing the chain or belt guard to ensure proper clearance. Slightly longer shocks can slightly alter the head angle, resulting in quicker steering, while shorter shocks may slow steering response. For heavy-duty applications, these shocks are recommended for bikes operated near the maximum load rating over 50% of the time, providing the durability needed for demanding conditions.\u003cbr\u003eBefore selecting shocks that differ from OEM length, verify that your wheel travel can accommodate the change without clearance issues, such as contact with the exhaust, swingarm, axle, chain or belt guard, or tires. Proper installation and adjustment ensure optimal performance and safety, making the Progressive Suspension 412 Series Shock an excellent upgrade for your Harley-Davidson motorcycle.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models, ensuring a perfect fit and reliable performance\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\u003eAvailable in multiple 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\u003eMade in the USA with durable construction for long-lasting performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeasurement 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, ideal for bikes operated near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustable length to modify steering response and handling characteristics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with Harley models from 1986 to 2015, with possible modifications for installation\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966857699525,"sku":"412-4019B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/160862.png?v=1773695377","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-12-5-inch-heavy-duty-black-for-harley-davidson-412-4019b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
