XRE series chains are available in 520, 525 \u0026amp; 530 pitch. XRE's features create a perfect balance between high tensile strength, lightweight while maximizing wearlife.","brand":"RK Chain","offers":[{"title":"Default Title","offer_id":47921011589365,"sku":"RKC520XRE-108","price":138.43,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0720\/6744\/9077\/files\/5b1ffde0648e5d5f816356773b04959c_4e5d2b58-9e81-4b18-a15a-9f1bfb8a8333.jpg?v=1775284014","url":"https:\/\/bills-exhausts.com\/ja\/products\/rk-chain-520xre-108l-xw-ring-natural","provider":"Bill's Exhausts","version":"1.0","type":"link"}
