No special tools needed.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between standard and heavy-duty spring rates?\u003c\/h3\u003e\n\u003cp\u003eHeavy-duty springs support more load and provide firmer support. Standard springs suit lighter loads. Choose based on your bike's weight and riding style.\u003c\/p\u003e\n\u003ch3\u003eAre these made in the USA?\u003c\/h3\u003e\n\u003cp\u003eYes — Progressive manufactures these shocks in the USA and backs them with a Limited Lifetime Warranty.\u003c\/p\u003e\n\u003ch3\u003eDo I need to revalve these shocks later?\u003c\/h3\u003e\n\u003cp\u003eThe 444's Frequency Sensing Technology adapts automatically as you ride, eliminating the need for manual revalving in most street-riding scenarios.\u003c\/p\u003e\n\u003ch2\u003eCalifornia Proposition 65 Warning\u003c\/h2\u003e\n\u003cp style=\"font-size:11px;color:#888;\"\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e Cancer and Reproductive Harm — California Prop 65 (Y). www.P65Warnings.ca.gov\u003c\/p\u003e","brand":"Progressive","offers":[{"title":"Default Title","offer_id":53040149299311,"sku":"T14-614103","price":860.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_203f5ef2-4527-42a4-9565-98b1ca90fe77.png?v=1779565685","url":"https:\/\/vtwinbikers.com\/products\/progressive-444-shocks-harley-davidson-9","provider":"Vtwinbikers","version":"1.0","type":"link"}
