This is a brand new 3-row aluminum radiator made for 1999-2004 Ford F-250, F-350, and F-450 Super Duty trucks with either the 6.8L V10 or 7.3L V8 diesel engines. The radiator is all-aluminum construction which cools better than old copper/brass ones and weighs less. It's performance/custom fitment, meaning it might be an upgrade over stock in some ways. Size is 30 inches by 31.75 inches by 4.75 inches overall, with 1.75 inch inlet and outlet diameters. Weighs about 26.4 pounds, comes with a cap included. Brand is losangeles5252 (sounds like a seller name), but they offer a 1-year warranty which is nice. It's been durability tested and 100% leak tested before shipping. Fits OEM part numbers like 2171, DPI 2171, CU2171, etc. The 3-row design means more cooling capacity than 2-row radiators, good for towing, hot climates, or if your truck runs hot. Silver aluminum color, not painted. This is a direct replacement if your original radiator is cracked, leaking, or just not keeping up anymore. Easy enough for a DIY mechanic to install with basic tools. Just make sure your truck is 1999-2004 Super Duty with the right engine - the 7.3L Power Stroke guys will love this. Keeps your big Ford running cool when you're working it hard.
