Rear End Breather Kit 1-1/2in. Bar

The Rear End Breather Kit 1-1/2in. Bar by LONGACRE is an essential upgrade for serious drag racers, road race competitors, and modified vehicle enthusiasts running higher horsepower applications. This kit is designed to prevent pressure buildup and moisture accumulation inside the rear axle housing, which can degrade gear oil and lead to seal failure during high-performance driving.

Featuring a 1-1/2-inch diameter inlet, this bar-mounted breather kit efficiently routes exhaust vapors away from critical drivetrain components while maintaining proper internal pressure regulation. The robust design ensures efficient airflow without creating backpressure on the differential housing. The bar mounting system integrates seamlessly with most bolt-on roll cage and frame tubes, simplifying installation.

Ideal for bracket racers, road course competitors, and street performance enthusiasts, this breather kit delivers reliable vapor management across thousands of miles of high-load operation. It performs well on both naturally aspirated and forced-induction platforms, making it a versatile choice for various applications.
