This feature ensures a tailored riding experience, whether you're cruising on highways or tackling twisty roads. Crafted in the USA, the PROGRESSIVE SUSPENSION 412 series delivers quality and craftsmanship that meet high standards. \u003cbr\u003e Available in different styles, such as full show-chrome or black covers, along with chrome or black springs and end caps, these shocks can be matched to your bike's aesthetic. It's important to note that some shocks listed are approved for road use; always check the latest certification for compliance. When installing shocks on 1986-2015 XL models, modifications to the chain or belt guard may be necessary to ensure proper clearance. Slightly longer shocks can alter the head angle for quicker steering, while shorter shocks may slow steering response. Heavy-duty applications are recommended for bikes frequently operating near maximum load capacity, over 50% of the time. Before installing shocks that differ in length from OEM specifications, verify that wheel travel and clearance issues, such as swingarm or axle contact with exhaust or tires, are addressed to prevent potential problems. This shock's versatile design and premium features make it a reliable upgrade for Harley enthusiasts seeking improved suspension performance. \u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley FLH models for optimal compatibility\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003e13.5-inch length offers balanced ride height and stability\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFive-position cam-style spring preload adjuster for customized suspension tuning\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy-duty construction suitable for maximum load applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMade in the USA with high-quality craftsmanship\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAvailable in various styles including full show-chrome or black covers\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCan alter steering response: longer shocks for quicker steering, shorter for slower handling\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRequires potential modifications on 1986-2015 XL models for clearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper wheel travel and clearance before installation to prevent contact issues\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966973894853,"sku":"412-4021B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159892.png?v=1773696670","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-13-5-inch-heavy-duty-black-for-harley-flh-models-part-412-4021b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
