Constructed with durability in mind, these shocks feature a simple yet robust design that ensures long-lasting reliability. The chrome finish adds a sleek, polished look that complements your bike's aesthetic while providing resistance against corrosion and the elements. Designed to improve ride comfort and handling, the 412 Series shocks are a popular choice among Harley enthusiasts seeking a balance of performance and style.\u003c\/p\u003e\u003cp\u003eEquipped with a five-position cam-style spring preload adjuster, these shocks allow riders to easily customize the ride height and firmness to suit their preferences or riding conditions. Whether you're carrying a passenger, hauling gear, or riding on rough terrain, adjusting the preload ensures optimal handling and comfort. It's important to note that some or all shocks listed are approved for road use; always refer to the latest certification documentation for compliance. The shocks are measured from center-of-eyelet to center-of-eyelet, ensuring compatibility with your specific application.\u003c\/p\u003e\u003cp\u003eInstallation considerations include potential modifications to the chain or belt guard on '86-'15 XL models to ensure proper clearance. Slightly longer shocks can subtly alter the head angle, providing quicker steering, while slightly shorter shocks may slow steering response. For bikes operated at or near maximum load capacity most of the time, Heavy Duty applications are recommended. Before switching to shocks of a different length than the OEM, verify that wheel travel can be adjusted without clearance issues such as contact with the exhaust, swingarm, or tires. Available in multiple styles including full show-chrome or black covers, as well as chrome or black springs and end caps, these shocks can be customized to match your bike's appearance. Made in the USA, the Progressive Suspension 412 Series Shock offers a reliable, stylish upgrade for Harley FLH owners seeking improved handling and ride quality.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley FLH models for optimal fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChrome finish for corrosion resistance and aesthetic appeal\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\u003eMeasured from center-of-eyelet to center-of-eyelet for compatibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in multiple style options including chrome or black covers and springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality materials\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for road use; always check current certification\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCan influence steering response depending on shock length adjustments\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy Duty applications recommended for maximum load conditions\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInstallation may require modifications on certain Harley models to ensure clearance\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966974517445,"sku":"412-4073C","price":379.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159902.png?v=1773696783","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-for-harley-flh-13-5-inch-chrome","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
