Constructed with a robust design, these shocks are an affordable way to improve ride comfort and handling, particularly for riders who frequently operate under heavy loads or aggressive riding conditions. The 412 series features a five-position cam style spring load preload adjuster, allowing you to easily fine-tune your ride for optimal comfort and performance without the need for additional tools. These shocks are made in the USA, ensuring high-quality craftsmanship and reliability. They are available in various style options, including full show-chrome or black covers, with either chrome or black springs and end caps, allowing you to customize the appearance of your motorcycle while enhancing its suspension system. All shocks are measured from center-of-eyelet to center-of-eyelet, ensuring proper fitment for compatible models. When installing these shocks on '86-'15 XL models, some modification or spacing of the chain or belt guard may be required to ensure proper clearance. Slight variations in shock length can subtly alter the head angle, affecting steering response—longer shocks tend to provide quicker steering, while shorter shocks may result in slightly slower handling. For bikes operated near or at their maximum load capacity over 50% of the time, Heavy Duty applications are recommended to ensure durability and safety. Before purchasing or installing shocks that differ from the OEM length, verify that your wheel travel and clearance are sufficient to prevent contact with exhaust components, swingarm, axle, chain or belt guard, and tires. This comprehensive shock system is designed to provide a significant upgrade over stock, improving both ride quality and motorcycle control, whether you're riding on the street or tackling challenging terrains.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley Davidson models for perfect fitment\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam style spring preload adjuster for customizable ride comfort\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy Duty construction ideal for high load applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in various style options including chrome and black finishes\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\u003eMeasurement from center-of-eyelet to center-of-eyelet ensures proper compatibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for a range of Harley models including '86-'15 XL, with possible minor modifications\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031860117598,"sku":"13100890","price":345.76,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/159907.png?v=1784493493","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-412-series-shock-12-inch-heavy-duty-black-for-harley-davidson-part-412-4081b","provider":"V-TwinVisionary","version":"1.0","type":"link"}
