Driveshaft Shop 3.25" Carbon Fiber 1-Piece Direct Fit CV Driveshaft (610278) - 2015-2024 Mustang Shelby GT350 / Mach 1 / Dark Horse Manual
Upgrade the drivetrain in your manual-transmission Shelby GT350, Mach 1, or Dark Horse with the Driveshaft Shop 3.25" Carbon Fiber 1-Piece Direct Fit CV Driveshaft. Designed as a high-performance replacement for the factory soft rubber-mounted driveshaft, the DSS 610278 combines lightweight carbon fiber construction with solid connections, a precision-ground direct-fit rear CV, Chromoly components, and a Spicer 1350 solid U-joint. With a 1,000+ horsepower rating, this driveshaft is built to support serious performance applications.
Previously offered under part number FDSH60-C, the latest DSS design eliminates the separate adapter plate at the rear differential. Instead, the precision-ground CV fits directly inside the pinion flange similar to the factory driveshaft. Eliminating the adapter plate reduces unnecessary weight while increasing power-holding capability and improving drivetrain response.
Direct-Fit Rear CV Design
The Driveshaft Shop developed the 610278 with a direct-fit rear CV designed for the supported manual-transmission Shelby GT350, Mach 1, and Dark Horse applications. The precision-ground CV fits directly inside the pinion flange rather than requiring a separate rear adapter plate.
This updated configuration eliminates unnecessary adapter weight while creating a more direct connection to the rear differential. DSS designed the system to increase power-holding capability, improve drivetrain response, and provide proper alignment.
3.25" Carbon Fiber 1-Piece Construction
At the center of the DSS 610278 is a 3.25" diameter carbon fiber shaft. The performance-oriented 1-piece configuration replaces the factory soft rubber-mounted driveshaft with solid connections designed to efficiently transfer increased engine output through the driveline.
The carbon fiber tube is paired with billet aluminum endcaps, 300M Chromoly spline plugs, a heavy-duty CV assembly, and a forged aluminum U-joint flange to create a complete driveline upgrade for high-performance Mustang applications.
Built for Shelby GT350, Mach 1 and Dark Horse
The DSS 610278 provides a dedicated carbon fiber driveshaft solution for several of Ford's performance-focused manual Mustang configurations. It is designed for the Shelby GT350, Mach 1, and Dark Horse applications listed below, providing an application-specific upgrade for these factory manual-transmission drivetrains.
Whether installed in a Shelby GT350, Mach 1, or S650 Dark Horse, the direct-fit design combines lightweight carbon fiber construction with heavy-duty driveline components to provide a substantial upgrade from the factory driveshaft.
1,000+ Horsepower Rating
The Driveshaft Shop rates the 610278 for more than 1,000 horsepower, providing substantial power-handling capacity for modified Mustang applications. This makes it suitable for vehicles ranging from bolt-on combinations to extensively modified high-horsepower builds.
The 3.25" carbon fiber shaft, 300M Chromoly spline plugs, Chromoly CV internals, Spicer 1350 solid U-joint, and forged aluminum flange work together to provide the strength required to transfer serious power to the ground.
300M Chromoly Spline Plugs
DSS equips the 610278 with 300M Chromoly spline plugs for increased strength in critical areas of the driveshaft assembly. These high-strength components are designed to withstand the additional driveline loads associated with modified and high-output performance applications.
High-Speed Precision-Ground CV Joint
The rear of the driveshaft utilizes a high-speed precision-ground CV joint with Chromoly internal components. In addition to providing the direct-fit connection inside the pinion flange, this CV joint provides twice the operating range of the previous DSS design.
The increased range provides additional articulation capability while retaining the strength and precision required for demanding performance use.
Spicer 1350 Solid U-Joint
The DSS 610278 incorporates a Spicer 1350 series solid U-joint paired with a forged aluminum U-joint flange. This heavy-duty combination provides a strong mechanical connection designed to handle substantially increased drivetrain loads.
Combined with the Chromoly CV internals and 300M Chromoly spline plugs, the Spicer 1350 solid U-joint contributes to the driveshaft's 1,000+ horsepower capability.
Billet Aluminum Endcaps
Billet aluminum endcaps are incorporated into the carbon fiber driveshaft assembly, complementing the 3.25" carbon fiber tube and the other heavy-duty driveline components. The result is a purpose-built 1-piece driveshaft designed around strength, reduced unnecessary weight, and performance.
Improved Drivetrain Response
The factory Mustang driveshaft uses soft rubber-mounted components that introduce compliance into the driveline. The DSS 1-piece driveshaft replaces that arrangement with solid connections designed to create a more direct mechanical link between the transmission and rear differential.
The carbon fiber construction, direct-fit rear CV, solid connections, and elimination of the separate rear adapter plate work together to improve drivetrain response while maintaining proper alignment.
Required Rear Subframe / Cradle Lock-Out Kit
WARNING: A rear subframe/cradle lock-out kit MUST be installed on the vehicle BEFORE installing the Driveshaft Shop 1-piece driveshaft.
The rear cradle must be properly reinforced and its movement limited before driveshaft installation. Any damage to the driveshaft, or any subsequent damage caused by failing to properly reinforce the rear cradle and limit movement, will void any and all warranty provided by The Driveshaft Shop.
This is a mandatory installation requirement and should not be considered an optional supporting modification.
Emergency Brake Cable Clearance
IMPORTANT: Emergency brake cable bracket clearance must be checked during installation. Clearance adjustment or relocation of the emergency brake cable bracket may be necessary.
Failure to verify and provide adequate clearance may allow the emergency brake cable bracket to contact and damage the driveshaft. Failure to check this clearance may damage the driveshaft and void the warranty.
