Cummins®

The Jacobs Exhaust Brake Pre 1998, identified by part number 3381391 and manufactured by Cummins, is a significant component in the commercial trucking industry. This system is designed to enhance the operational efficiency and safety of heavy-duty trucks, particularly during descents.

Purpose and Functionality

The Jacobs Exhaust Brake Pre 1998 is engineered to assist in engine braking, a mechanism that helps control vehicle speed and reduces the reliance on traditional braking systems. By redirecting exhaust gases, it creates backpressure in the engine, which in turn slows down the vehicle. This system is particularly beneficial during downhill driving, where it aids in maintaining a safe speed and reducing the strain on the truck’s braking system ¹.

Key Features

This Cummins part is characterized by its robust design and construction, primarily using durable materials to withstand the harsh conditions of heavy-duty trucking. Its unique attributes include a compact design that integrates seamlessly with the truck’s exhaust system and a reliable operation mechanism that ensures consistent performance under varying driving conditions.

Benefits

The integration of the Jacobs Exhaust Brake Pre 1998 into a truck’s system offers several advantages. It enhances vehicle control, especially during descents, by providing an additional braking force. This reduces the wear and tear on the transmission and brakes, leading to longer component lifespans and lower maintenance costs. Additionally, it contributes to enhanced safety by allowing for more controlled and gradual deceleration ².

Installation and Integration

Installing the Jacobs Exhaust Brake Pre 1998 involves integrating it into the truck’s exhaust system. This process may require specific modifications to ensure compatibility and optimal performance.
