It has been almost 30 years since we started shipping our first exhaust brakes. With that many hill and mountain roads experienced, we used the knowledge gained to continue to deliver the best designed exhaust brake for your application. Incorporating BD's exclusive Variable Orifice Technology, BD's solid, offset butterfly, spring loaded cylinder and pressure regulation provides up to 150 retarding horsepower throughout the engine's RPM range - not just at high rpm like some designs that use holes or additional parts and claim it as a better idea. A range of rugged, cast-iron housings for Dodge, Ford, Chevy and motor home applications that incorporate BD's exclusive alumibronze bushing, piston ring-seals and stainless steel butterfly shaft has proven to stand-up under the harsh, high heat conditions of the exhaust environment. BD's butterfly valve and rotating shaft are made of stainless steel to resist corrosion. An air compressor is included in most kits for newer pick-up trucks.Installation InstructionsThis Part Fits: Year Make Model Submodel 2007-2010 Dodge Ram 2500 Laramie 2007-2010 Dodge Ram 2500 SLT 2007-2010 Dodge Ram 2500 ST 2008-2010 Dodge Ram 2500 SXT 2010 Dodge Ram 2500 TRX 2007-2010 Dodge Ram 3500 Laramie 2007-2010 Dodge Ram 3500 SLT 2007 Dodge Ram 3500 Sport 2007-2010 Dodge Ram 3500 ST 2008-2010 Dodge Ram 3500 SXT 2013-2017 Ram 2500 Big Horn 2011-2017 Ram 2500 Laramie 2014-2015 Ram 2500 Laramie Limited 2011-2017 Ram 2500 Laramie Longhorn 2016-2017 Ram 2500 Limited 2013-2015 Ram 2500 Lone Star 2012-2016 Ram 2500 Outdoorsman 2011-2017 Ram 2500 SLT 2011-2013 Ram 2500 ST 2013-2017 Ram 2500 Tradesman 2013-2017 Ram 3500 Big Horn 2011-2017 Ram 3500 Laramie 2014-2015 Ram 3500 Laramie Limited 2011-2017 Ram 3500 Laramie Longhorn 2016-2017 Ram 3500 Limited 2013-2015,2017 Ram 3500 Lone Star 2011-2017 Ram 3500 SLT 2011-2013 Ram 3500 ST 2013-2017 Ram 3500 Tradesman

Descending grades with trailers can be hazardous and tricky situations, resulting in over heated service and trailer brakes, that leads to brake fade, excessive wear, and costly unwarranted repairs. BD Engine brake has been the industries time proven VARIABLE REGULATING BACK-PRESSURE EXHAUST BRAKE.Controlled by a lighted On/Off toggle switch or optional stick-mounted rocker switch for manual transmissions, the BD brake communicates with the engines electronic idle verification board for quick engagement. Where it mounts: Most vehicle applications will either have BDs turbo-mount design which bolts in place of the factory elbow between the turbo and the exhaust system or the inline design mounts in the exhaust system between the engine and muffler/DPF/cat. The BD Brakes rugged cast-iron housing incorporates BDs exclusive AlumiBronze bushing and positive sealing piston ring, no blind holes for carbon and rust to form, and miles of leak free retarding. Brake valve is actuated by an air cylinder (newer models) or a powerful, three-inch vacuum cylinder (earlier models). The durable air compressor included in later model kits can even be used for other applications, such as air horns, air bags even air-ride fifth wheel hitches –it is that tough. Automatic-equipped trucks prior to 2006 require BDs programmable AutoLoc and PressureLoc kits to electronically control torque converter clutch engagement. This addition effectively reduces slippage, resulting in peak retarding performance as well as lower transmission temperatures. All BD Brake kits come complete with the brake, air compressor (where applicable), mounting hardware, port to monitor the brakes retarding performance, complete instructions and most models come with EGT port.Installation InstructionsInstallation InstructionsThis Part Fits: Year Make Model Submodel 2003,2005 Dodge Ram 2500 Laramie 2003-2005 Dodge Ram 2500 SLT 2003-2005 Dodge Ram 2500 ST 2003-2005 Dodge Ram 3500 Laramie 2003-2005 Dodge Ram 3500 SLT 2003-2005 Dodge Ram 3500 ST
