BD Diesel 1028140 Exhaust Brake Remote Mount Air Actuated with Compressor - 4.0 Inch

The BD Diesel 1028140 is a universal remote-mount exhaust brake designed for diesel trucks and motor homes, featuring a 4.0-inch air-actuated butterfly valve system with integrated air compressor. This heavy-duty braking solution delivers enhanced vehicle control and reduced brake wear on steep grades and mountain descents.

Variable Orifice Technology:

BD's exclusive Variable Orifice Technology with solid, offset butterfly design provides up to 150 retarding horsepower consistently throughout the engine's RPM range. The pneumatic spring-loaded cylinder with adjustable pressure regulation ensures optimal braking performance across all driving conditions, not just at high RPM like competitive designs.

Rugged Construction:

• Cast-iron housing engineered to withstand extreme exhaust temperatures
• Stainless steel butterfly valve and shaft for superior corrosion resistance
• Exclusive alumibronze bushing for durability
• Piston ring-seals for reliable air-tight operation
• Proven performance in harsh exhaust environments

Installation & Compatibility:

Estimated installation time is 4 hours. All mounting hardware included. Brake controls connect to throttle pedal with Accelerator Pedal Position Sensor (APPS). Vehicles without APPS require BD part number 1300420 micro switch and custom bracket fabrication. Compatible with aftermarket non-VGT turbos; may not function with OEM Variable Vane (VGT) turbos such as Cummins ISX. Back pressure test gauge kit (BD 1030050) recommended for proper setup.
