Constructed with a simple, durable design, these shocks are built to withstand rigorous riding conditions while offering a smooth, controlled ride. The 412 Series features a five-position cam-style spring preload adjuster, allowing riders to easily customize the suspension settings for different loads and riding styles, ensuring optimal comfort and handling. Made in the USA, these shocks are available with various style options, including full show-chrome or black covers, along with chrome or black springs and end caps, enabling riders to personalize their motorcycle's appearance while maintaining high-quality performance. These shocks are measured from center of eyelet to center of eyelet, ensuring compatibility with a range of Harley models from 1986 to 2015. When installing on certain models, such as the XL series, modifications like spacing the chain or belt guard may be necessary to ensure proper clearance. Slight variations in shock length can influence steering dynamics; a longer shock may result in a marginally quicker steering response, while a shorter shock can provide a slightly slower turn-in. For riders operating near the maximum load capacity, Heavy Duty applications are recommended to ensure durability and performance. Before installing shocks that differ from OEM length, it is important to confirm that wheel travel and clearance are sufficient to avoid contact with exhaust, swingarm, axle, or tires, maintaining safe and effective operation of the motorcycle.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eDesigned specifically for Harley-Davidson models to improve suspension performance\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 with full show-chrome or black covers, and chrome or black springs and end caps\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eConstructed in the USA with durable materials for long-lasting performance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eMeasurement from center of eyelet to center of eyelet ensures proper fit on Harley models\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSuitable for models from 1986 to 2015, with potential modifications for certain applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eProvides options for slightly longer or shorter shocks to influence steering dynamics\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eHeavy Duty applications recommended for high load or frequent maximum load operation\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eEnsure proper clearance and wheel travel compatibility before installation\u003c\/li\u003e\u003c\/ul\u003e","brand":"PROGRESSIVE SUSPENSION","offers":[{"title":"Default Title","offer_id":45966986346693,"sku":"412-4064B","price":379.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0253\/7891\/4355\/files\/159257.png?v=1773697606","url":"https:\/\/btqllc.com\/products\/progressive-suspension-412-series-shock-12-5-inch-standard-black-model-412-4064b","provider":"Bikes Trikes and Quads LLC","version":"1.0","type":"link"}
