Driveshaft Shop 4" 1-Piece Aluminum Driveshaft – 2015+ Dodge Charger Scat Pack / SRT / SRT 392 | Automatic Transmission

Unlock the full potential of your 2015+ Dodge Charger Scat Pack, SRT, or SRT 392's naturally aspirated 6.4L 392 HEMI with the Driveshaft Shop 4" 1-Piece Aluminum Driveshaft (CHSH39-A) — engineered specifically for automatic transmission Charger Scat Pack, SRT, and SRT 392 models. This 4" diameter aluminum 1-piece shaft replaces the OEM 2-piece steel driveshaft, eliminating the center support bearing — a known failure point under high-power and high-RPM use. The result is a lighter, stronger, more balanced driveshaft that delivers power to the rear wheels more efficiently and reliably than the factory unit.

⚠️ Automatic Transmission & 6.4L 392 HEMI Only: This driveshaft is engineered for automatic transmission Charger Scat Pack, SRT, and SRT 392 models with the 6.4L 392 HEMI. Not compatible with Hellcat models (see CHSH38-A) or manual transmission configurations. Verify your engine and transmission before ordering.

Key Features

• 1-Piece Design – Eliminates Center Support Bearing: Replaces the OEM 2-piece driveshaft with a single 1-piece unit, eliminating the center support bearing — a known failure point under high-power and high-RPM use. Fewer components means fewer failure points and more consistent power delivery
• 4" Diameter Aluminum Construction: 4" diameter aluminum tube provides superior torsional rigidity and strength compared to the OEM steel 2-piece shaft, while being significantly lighter — reduced rotational mass improves throttle response and acceleration
• Automatic Transmission Specific: Engineered specifically for 2015+ Charger Scat Pack, SRT, and SRT 392 models with an automatic transmission — not compatible with manual transmission configurations
• 6.4L 392 HEMI Specific: Engineered for the naturally aspirated 6.4L 392 HEMI — a distinct driveshaft configuration from the supercharged Hellcat HEMI (CHSH38-A). Verify your engine before ordering
• Scat Pack, SRT & SRT 392 Coverage: Fits the 2015+ Charger Scat Pack, SRT, and SRT 392 trim levels with the 6.4L 392 HEMI and automatic transmission
• Driveshaft Shop Quality: Manufactured by the Driveshaft Shop (DSS) — the industry leader in high-performance driveshafts, axles, and drivetrain components for high-power builds
