Driveshaft Shop 3.5" Aluminum 1-Piece Direct Fit CV Driveshaft (610273) - 2015-2026 Mustang EcoBoost 6-Speed Manual
Upgrade the drivetrain in your 2015+ Ford Mustang EcoBoost with the Driveshaft Shop 3.5" Aluminum 1-Piece Direct Fit CV Driveshaft. Built for 6-speed manual S550 Mustang EcoBoost applications, the DSS 610273 replaces the factory soft rubber-mounted driveshaft with a performance-focused 1-piece design featuring solid connections, a precision-ground direct-fit rear CV, and a 1,000+ horsepower rating.
Previously offered under part number FDSH61-A, 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 610273 with a direct-fit rear CV that eliminates the need for a separate adapter plate at the rear differential. The precision-ground CV fits directly inside the pinion flange in a configuration similar to the factory driveshaft.
This design eliminates unnecessary adapter weight while creating a more direct driveline connection. DSS engineered the new configuration to increase power-holding capability, improve drivetrain response, and provide proper alignment.
3.5" Aluminum 1-Piece Construction
The 610273 features a 3.5" diameter aluminum shaft designed to replace the factory driveshaft with a performance-oriented 1-piece configuration. The aluminum shaft is paired with billet aluminum endcaps and a forged aluminum U-joint flange for a complete driveline upgrade.
Replacing the factory soft rubber-mounted shaft with solid connections creates a more direct connection through the drivetrain, making the DSS driveshaft well suited for modified EcoBoost Mustang applications.
1,000+ Horsepower Rating
The Driveshaft Shop rates the 610273 for more than 1,000 horsepower, providing substantial power-handling capability for modified EcoBoost Mustang builds. Even extensively modified engine combinations can benefit from a driveshaft designed to handle considerably more power than the factory driveline was originally tasked with transferring.
The 3.5" aluminum shaft, 300M Chromoly spline plugs, Chromoly CV internals, Spicer 1350 solid U-joint, and forged aluminum flange work together to provide the strength required for demanding performance use.
300M Chromoly Spline Plugs
DSS equips the driveshaft with 300M Chromoly spline plugs for increased strength in critical areas of the assembly. These high-strength components are designed to withstand the increased drivetrain loads associated with modified and high-output Mustang applications.
High-Speed Precision-Ground CV Joint
The rear of the driveshaft uses a high-speed precision-ground CV joint with Chromoly internal components. In addition to providing the direct-fit connection at the pinion flange, the CV joint offers twice the operating range of the previous DSS design.
This increased range provides additional articulation capability while retaining the strength and precision required for demanding performance applications.
Spicer 1350 Solid U-Joint
The DSS 610273 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 300M Chromoly spline plugs and Chromoly CV internals, the Spicer 1350 solid U-joint contributes to the driveshaft's 1,000+ horsepower rating.
Improved Drivetrain Response
The factory Mustang driveshaft utilizes soft rubber-mounted components that introduce compliance into the driveline. The DSS 1-piece driveshaft replaces that arrangement with solid connections for a more direct mechanical connection between the transmission and rear differential.
The direct-fit rear CV, 1-piece aluminum construction, 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 prior to 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 adequate clearance may allow the emergency brake cable bracket to contact and damage the driveshaft. Failure to check and provide the necessary clearance may damage the driveshaft and void the warranty.
