Constructed with durability in mind, these shocks offer a cost-efficient solution to improve ride comfort and handling. The 412 series features a simple yet robust design that enhances performance while maintaining ease of installation. Made in the USA, these shocks are suitable for various Harley models and are engineered to meet the demands of both daily riding and heavier loads. \u003cbr\u003e \u003cbr\u003e The shocks come equipped with a five-position cam-style spring preload adjuster, allowing you to fine-tune your ride for optimal comfort and stability. Whether you're seeking a slightly stiffer response for aggressive riding or a softer feel for cruising, this adjustment feature provides versatile customization. The shocks are available in multiple styles, including full show-chrome or black covers, with options for chrome or black springs and end caps. This variety ensures you can match your bike's aesthetic preferences while benefiting from improved suspension performance. \u003cbr\u003e \u003cbr\u003e When installing these shocks on '86-'15 XL models, some modifications such as spacing the chain or belt guard may be necessary to ensure proper clearance. It's important to verify that your wheel travel can accommodate shocks that are slightly longer or shorter than stock without causing contact issues with the swingarm, exhaust, or tires. Slight changes in shock length can also influence steering characteristics, with longer shocks potentially providing quicker steering and shorter shocks offering a more relaxed turn. Heavy-duty applications are recommended for bikes regularly operating at or near maximum load capacities, ensuring durability and sustained performance. Proper installation and compatibility checks are essential to avoid clearance issues and to ensure your motorcycle maintains optimal handling and safety during operation.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models for seamless fit and performance\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\u003eConstructed with durable materials to enhance suspension longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMultiple style options including show-chrome or black covers and springs\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA ensuring quality and reliability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for various Harley models with center-to-center eyelet measurement\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty design recommended for bikes operating near maximum load capacity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatibility considerations for '86-'15 XL models, including potential modifications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjusts steering dynamics with slight length variations for tailored handling\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031990075486,"sku":"PS4050B","price":345.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/160859.png?v=1784499414","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-412-series-shock-for-harley-davidson-12-inch-heavy-duty-black-part-412-4050b","provider":"V-TwinVisionary","version":"1.0","type":"link"}
