You can fine-tune spring tension without removing the shock or using tools.\u003c\/p\u003e\n\u003ch3\u003eWhat's the difference between standard and heavy-duty spring rates?\u003c\/h3\u003e\n\u003cp\u003eStandard rate suits most riders at typical weight. Heavy-duty rate is for heavier riders or those carrying cargo regularly.\u003c\/p\u003e\n\u003ch3\u003eAre these shocks 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 bleed or service these shocks?\u003c\/h3\u003e\n\u003cp\u003eProgressive 444 shocks are sealed and self-adjusting — no manual bleeding or frequent service required during normal use.\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":53040149987439,"sku":"T14-614111","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_87f2cadd-0e98-43b9-8851-4eef809316b1.png?v=1779565941","url":"https:\/\/vtwinbikers.com\/products\/progressive-444-shocks-harley-davidson-15","provider":"Vtwinbikers","version":"1.0","type":"link"}
