The Driveshaft Shop 4″ Aluminum 1-Piece Direct Fit CV Driveshaft is a serious drivetrain upgrade engineered specifically for 2015+ Dodge Charger Hellcat and Redeye models equipped with an automatic transmission. Designed to replace the factory soft rubber-mounted shaft, this one-piece aluminum driveshaft provides solid connections, precise alignment, and improved power transfer for high-horsepower Gen 3 HEMI applications. Its direct-fit rear CV design eliminates the traditional adapter plate and uses a precision-ground CV that fits inside the pinion flange similarly to the factory configuration. Chromoly CV internals add strength where it matters, while the aluminum shaft helps create a responsive drivetrain capable of supporting substantial power. Rated by The Driveshaft Shop for 1,200 horsepower, this driveshaft is built for everything from modified street Hellcats to aggressive drag racing combinations.

One of the biggest advantages of this design is the elimination of the rear adapter plate. Rather than adding another component between the driveshaft and differential, The Driveshaft Shop developed a precision-ground rear CV that interfaces directly with the pinion flange. Removing the adapter plate reduces unnecessary weight while helping improve power-holding capability and drivetrain response. The manufacturer describes the result as a significant upgrade from the softer factory rubber-mounted shaft.

For Charger Hellcat and Redeye owners increasing supercharger boost, running E85, upgrading the camshaft, or building a more aggressive engine combination, strengthening the drivetrain becomes increasingly important. More horsepower and improved traction can expose weaknesses that may not appear at factory power levels. The DSS driveshaft provides a purpose-built solution for transferring that additional Gen 3 HEMI power toward the rear differential.

The 4-inch aluminum construction combines strength with a design engineered specifically for performance use. The new CV assemblies feature Chromoly internals, and the manufacturer rates the complete driveshaft at 1,200 horsepower. The assembly weighs approximately 40 pounds and measures 81 x 6 x 6 inches according to the manufacturer’s published product specifications.

Installation requirements are particularly important with this upgrade. The Driveshaft Shop requires a rear subframe/cradle lockout kit to be installed before the one-piece driveshaft. Failure to properly reinforce the rear cradle and limit its movement can damage the driveshaft and void the manufacturer’s warranty. The manufacturer also notes that 2015+ applications do not require spacers, although exhaust modification may be necessary to maintain approximately 0.75 inches of adequate driveshaft clearance.

Fitment is specific. This version, part number CHSH38-A, is intended for 2015+ Dodge Charger Hellcat automatic applications, with the current product listing specifically identifying both Hellcat and Redeye models. It will not fit SRT or Scat Pack models, so it should not be treated as a universal LX-platform driveshaft.

Whether you’re building a street-driven Charger with additional power or preparing a Hellcat or Redeye for repeated drag strip launches, the DSS 4″ Aluminum 1-Piece Driveshaft provides the increased strength, direct-fit design, and power capacity needed for a more capable Gen 3 HEMI drivetrain.
