Driveshaft Shop X6 2000HP Rated Direct-Fit Left Rear Axle (510451) - 2020-2022 Shelby GT500
Put serious power to the ground in your 2020-2022 Shelby GT500 with the Driveshaft Shop X6 Rated Direct-Fit Left Rear Axle. Developed as part of DSS's ongoing pursuit of stronger, more capable axle solutions, the X6 Rated Line is engineered for high-powered street cars that also see occasional drag strip, road course, or autocross use.
The DSS 510451 is the left rear axle for the 2020-2022 Mustang Shelby GT500 and is designed as a direct bolt-in replacement. Built using premium 300M materials and advanced heat-treatment processes, the X6 axle is engineered to withstand the demands created by extreme horsepower while remaining appropriate for performance street applications.
X6 Rated for Extreme Power
The Driveshaft Shop X6 Rated Line was engineered specifically for fast street cars producing substantial power. Depending on the application, X6 axles are designed to handle approximately 1,400 to 2,000 wheel horsepower, giving serious performance builds the axle strength required for demanding use.
For the 2020-2022 Shelby GT500 application, the 510451 is offered as a 2,000HP-rated axle, providing substantial capacity for vehicles operating well beyond factory power levels.
Engineered for High-Powered Street and Track Builds
DSS developed the X6 Rated Line with powerful street-driven vehicles in mind rather than limiting the design to a single type of motorsport. These axles are intended for cars that spend time on the street but may also see occasional drag racing, road course, or autocross duty.
That versatility makes the 510451 a strong driveline upgrade for GT500 owners building around increased horsepower while still using the vehicle across multiple types of performance driving.
Premium 300M Construction
The X6 axle utilizes some of the industry's high-quality 300M materials combined with specialized heat-treatment processes. DSS selected these materials and manufacturing processes to provide the strength required to withstand the severe drivetrain loads generated by high-horsepower applications.
The result is an axle engineered to take the abuse associated with putting substantial power through the GT500 drivetrain.
Direct Bolt-In Design
The DSS 510451 is designed as a direct bolt-in axle for the supported Shelby GT500 application. Rather than requiring a universal axle solution, the X6 axle is engineered around the specific vehicle application for straightforward integration into the factory-style drivetrain configuration.
Left Rear Axle
The DSS 510451 is a LEFT REAR axle. This listing is for the left side axle rather than a complete pair. When servicing or upgrading both sides of the vehicle, verify the correct corresponding axle for the opposite side before ordering.
