Everything you need to know before you sell
The 25314-774-21H is an OEM catalytic converter used on the 2005–2011 GMC Sierra 3500. It is classified as a Diesel Particulate Filter (DPF) and weighs approximately 13.5 lbs. Diesel Particulate Filters (DPFs) are used in diesel-powered vehicles to trap soot and particulate matter. They contain platinum and palladium and have significant scrap value when recycled properly.
Like all catalytic converters, the 25314-774-21H contains three platinum group metals (PGMs): platinum, palladium, and rhodium. These metals are embedded in the ceramic or metallic honeycomb substrate inside the converter shell. When the converter reaches the end of its service life, these metals can be recovered through a refining process and sold on the precious metals market.
Based on typical assay results for the 25314-774-21H unit, this converter contains approximately 3.89 grams of platinum, 4.61 grams of palladium, and 0.71 grams of rhodium. At current spot prices (platinum $1,050/troy oz, palladium $1,020/troy oz, rhodium $4,800/troy oz) and a standard 72% recovery rate, the gross metal value works out to approximately $281.
The actual price offered by a recycler will depend on the condition of the converter, the current PGM market, and the recycler's processing costs.
