This allows RK to design a Sealed Chain with the weight of a Non-Sealed Chain. MRU will feature 4 times longer chain life than comparable non-sealed 420 chains and will require less chain adjustments compared to non-sealed 420 chains. MRU is available in RK’s Black Scale finish with black inner and black outer sideplates with gold pins and gold rollers.","brand":"RK Chain","offers":[{"title":"Default Title","offer_id":67884472139930,"sku":"RKCBL420MRU-120","price":144.04,"currency_code":"USD","in_stock":true}],"url":"https:\/\/throwdownperformance.com\/products\/rk-chain-mru420-120-u-ring-chain","provider":"Throwdown Performance, LLC","version":"1.0","type":"link"}
