THE ULTIMATE THERMAL MANAGEMENT FOR 2013-2018 RAM HEAVY DUTY TRUCKS Keep your hard-working Ram 2500, 3500, or Chassis Cab running at its absolute thermal peak with the Zarklenu High-Performance 2 Row Performance Aluminum Radiator. Specifically engineered for the 6.7L Cummins Diesel and 6.4L HEMI V8 platforms, this heavy-duty radiator provides the ultimate high-performance solution for towing, hauling, and demanding job sites. Whether you are moving massive trailers or navigating tough terrain, our all-aluminum 2-Row construction provides the massive reliability and cooling margins required to protect your engine. RACING GRADE CONSTRUCTION FOR MAXIMUM RELIABILITY Factory radiators with plastic tanks are a common failure point under the high pressure of diesel cooling systems; the Zarklenu radiator eliminates this risk with a full TIG-welded, aircraft-grade aluminum build. Our dual-core design offers far superior structural integrity and significantly better heat transfer than restrictive OEM units. Built for a leak-proof lifespan and featuring a high-performance 2 Row core paired with an integrated transmission oil cooler and a precise high-pressure cap, it is the essential upgrade for any Ram owner who values long-term durability and peak engine protection for their heavy-duty truck.
