{"product_id":"rk-chain-mru420-u-ring-clip-link","title":"RK Chain MRU420 U-Ring Clip Link","description":"The RK MRU U-Ring Chain features a proprietary ultra-thin seal (U-Rings) where the thickness of the seal is less than 50% of the most common O-ring seal. This allowed RK to design a sealed chain with the same weight as a non-sealed chain. The MRU features a chain life over four times longer than comparable non-sealed 420 chains while also requiring less chain adjustments.","brand":"RK Chain","offers":[{"title":"Default Title","offer_id":51850452435157,"sku":"RKCBL420MRU-CL","price":5.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.trumotorsports.com\/products\/rk-chain-mru420-u-ring-clip-link","provider":"trumotorsports","version":"1.0","type":"link"}
