Built to stop heavy loads, stop after stop — the Wagner SevereDuty Rear Disc Brake Rotor (DSX180310E) is engineered for fleet, delivery, municipal and work trucks that brake hard under weight. It installs as a direct-fit rear rotor for the listed applications: the 2009-2010 Dodge Ram 2500 and Ram 3500, the 2012 Ram 1500, and the 2011-2025 Ram 2500 and Ram 3500 (all engines).
- Extreme durability: high-carbon, lightly alloyed metallurgy engineered to OE dimensions for high strength and heat management at high temperatures.
- Vented, full-cast design: application-specific OE vane design and thickness help control noise, vibration and harshness (NVH).
- Resists corrosion: painted edges and hats provide reliable corrosion resistance.
- Precision finish: a precision-ground smooth surface requires less pad break-in time and aids proper bedding, and is precision-machined to limit vibrations for improved stability, control and reduced pad wear.
This rear rotor has a 14.094 in (358 mm) outside diameter and a nominal thickness of 1.339 in (34.0 mm), with vented, full-cast construction and a smooth surface. Sold individually (minimum order quantity 1); the listed applications use two, so it's best to replace both rear sides together as a matched set for even, balanced braking. Pair with Wagner PPV or SD brake pads for use under demanding conditions. Country of origin: China. Manufacturer part number DSX180310E.
