BD Diesel 1027344 Exhaust Brake Remote Air System 4.0" Cummins 6.7L Non-VGT Turbo

The BD Diesel 1027344 is a remote-mounted exhaust brake system designed specifically for 2007.5-2017 Dodge Ram trucks equipped with the Cummins 6.7L engine and non-VGT (Variable Geometry Turbo) aftermarket turbochargers. This remote air-actuated system is ideal when an aftermarket performance turbo prevents installation of a traditional turbo-mount exhaust brake.

Variable Orifice Technology

BD Diesel's exclusive Variable Orifice Technology delivers consistent braking performance across the entire RPM range. The solid, offset butterfly valve design with spring-loaded cylinder and pressure regulation provides up to 150 retarding horsepower, giving you confident control on steep descents and mountain roads. Unlike competing designs that only perform at high RPM, this system delivers reliable engine braking throughout your engine's operating range.

Built for Durability

Engineered to withstand the extreme heat and pressure of the exhaust environment, this brake features a rugged cast-iron housing with BD's proprietary alumibronze bushing and piston ring seals. The butterfly valve and rotating shaft are constructed from corrosion-resistant stainless steel, while all mounting hardware uses stainless steel to ensure long-term reliability. These premium materials have proven their durability over nearly three decades of real-world testing.

Complete Kit with Air Compressor

This complete system includes an air compressor and all necessary mounting hardware for installation. The 4.0-inch exhaust housing is sized appropriately for the Cummins 6.7L application. Estimated installation time is approximately 4 hours. Note that this kit is designed for trucks that already have a factory exhaust brake switch on the dashboard; if your truck does not have this switch, order BD kit 1027340 instead.
