The BD Diesel Electronic Exhaust Brake 4.0IN (1027346) is a high-performance braking solution designed specifically for 2007.5–2012 Dodge Ram trucks equipped with the 6.7L Cummins engine. This exhaust brake enhances vehicle control and safety by providing additional braking power without relying solely on the vehicle’s service brakes, thereby reducing brake wear and extending component life. Unlike traditional mechanical brakes, the BD Diesel Electronic Exhaust Brake operates using a sophisticated electronic butterfly valve system that creates backpressure in the exhaust system to slow the vehicle efficiently. Engineered for seamless integration, it utilizes factory connections and requires no air compressor, making installation straightforward. Ideal for towing and hauling applications, this exhaust brake offers consistent and reliable braking performance, especially on steep grades and during heavy loads.
