Significant weight additions may require selecting a heavier spring rate when ordering.\u003c\/p\u003e\n\u003ch3\u003eAre these street legal?\u003c\/h3\u003e\n\u003cp\u003eYes — Progressive 444s are street-legal replacements for stock shocks and do not require emissions or DOT compliance modifications.\u003c\/p\u003e\n\u003ch3\u003eWhat spring rate should I choose?\u003c\/h3\u003e\n\u003cp\u003eStandard rate suits most stock Harley weights. Heavy duty is for riders carrying extra load (passenger, luggage, weight gain) or who prefer a firmer ride.\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":53040148742255,"sku":"T14-614093","price":860.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0608\/6734\/6543\/files\/output_a03995fb-cb4a-4f4b-a5b6-d65ad27ae200.png?v=1779565574","url":"https:\/\/vtwinbikers.com\/products\/progressive-444-shocks-harley-davidson-2","provider":"Vtwinbikers","version":"1.0","type":"link"}
