Exhaust Brake Universal 4in w/ Air Compressor

The Exhaust Brake Universal 4in with Air Compressor by BD DIESEL is a heavy-duty engine braking system designed specifically for diesel trucks, RVs, and commercial vehicles that require reliable descent control and extended brake life. This product is particularly beneficial for vehicles operating in mountainous terrain or towing heavy loads, providing enhanced braking performance.

Functionally, the exhaust brake operates by closing an internal butterfly valve when you release the throttle, which restricts exhaust flow and creates powerful compression braking forces without causing friction wear on brake pads or rotors. The integrated air compressor ensures consistent valve operation, providing immediate response under various load and altitude conditions. This design allows for smooth modulation, critical for safely controlling heavy vehicles without jarring the transmission or frame.

This universal 4-inch design fits most standard exhaust stacks, making it a versatile retrofit for existing systems. Owner-operators and fleet managers will find this exhaust brake particularly advantageous for improving safety and performance during long descents. Its compatibility with a wide range of diesel applications makes it a valuable addition to any serious diesel platform.
