With its robust construction and straightforward installation, this shock absorber provides a cost-effective way to improve ride comfort and handling. The 12.5-inch length is suitable for a range of Harley FLH\/T models, contributing to better stability and ride quality. Made in the USA, this shock features a sleek black finish that complements your bike's aesthetics and offers resistance to the elements for long-lasting durability. The component is engineered with a five-position cam-style spring preload adjuster, allowing riders to easily dial in the desired ride height and firmness for personalized comfort and handling. These shocks are designed for street use, with some models approved for road use, and it is advisable to check the latest certification for compliance. When installing on '86-'15 XL models, modifications to the chain or belt guard may be necessary for proper clearance, especially if opting for shocks slightly longer or shorter than stock. A longer shock can slightly alter the head angle, resulting in quicker steering, while a shorter shock may produce somewhat slower steering. For bikes frequently operated at or near maximum load capacity, Heavy Duty applications are recommended. Before purchasing shocks that differ from the OEM length, ensure your wheel travel can accommodate the change without causing clearance issues such as contact with the exhaust, swingarm, axle, or tires. The 412 Series Shock is available in various styles, including full show-chrome or black covers, with options for chrome or black springs and end caps, allowing customization to match your bike's aesthetic preferences and performance needs.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models for optimal fit and performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e12.5-inch length provides improved stability and handling\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 chrome or black covers, 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\u003eSuitable for street use, with some models approved for road compliance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAdjustments may be required for '86-'15 XL models to ensure proper clearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSlight variations in length can influence steering characteristics, providing quicker or slower response as desired\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy Duty applications recommended for frequent maximum load operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure wheel travel and clearance are adequate before installing shocks differing from OEM length\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":43031921819742,"sku":"13100477","price":345.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0012\/2545\/7758\/files\/159293.png?v=1784496228","url":"https:\/\/vtwinvisionary.com\/products\/progressive-suspension-412-series-shock-12-5-inch-standard-black-for-harley-flh-t-part-number-412-4071b","provider":"V-TwinVisionary","version":"1.0","type":"link"}
