BD Diesel 1028035 Universal Exhaust Brake 3.5 Inch Remote Mount Air Actuated

The BD Diesel 1028035 is a universal remote-mount exhaust brake designed for diesel engines, featuring a 3.5-inch inlet/outlet and pneumatic air actuation. Built on nearly three decades of engineering expertise, this exhaust brake delivers reliable engine braking performance for trucks, motor homes, and heavy-duty diesel applications.

Variable Orifice Technology:

BD's exclusive Variable Orifice Technology uses a solid, offset butterfly design with a spring-loaded cylinder and adjustable pressure regulation to provide up to 150 retarding horsepower throughout the engine's RPM range. Unlike competing designs that rely on fixed holes or ports, this system maintains consistent braking power from low to high RPM for superior control on steep grades and mountain descents.

Rugged Construction:

• Cast-iron housing built to withstand extreme exhaust temperatures
• Stainless steel butterfly valve and rotating shaft for corrosion resistance
• Exclusive alumibronze bushings for durability
• Piston ring seals for reliable operation
• Stainless steel shaft proven in harsh, high-heat exhaust environments

Installation and Compatibility:

This universal 3.5-inch exhaust brake is designed for remote mounting and includes all necessary mounting hardware. Estimated installation time is approximately 4 hours. Brake controls connect to the throttle pedal via Accelerator Pedal Position Sensor (APPS). Vehicles without APPS require BD part number 1300420 micro switch and a custom bracket. BD recommends using exhaust back pressure test gauge kit 1030050 for proper setup and adjustment.
