Why Install This?
Benefits
- Incremental gains that stack well with other bolt-on mods
- Lighter rotating mass means faster spool-up and quicker shifts
- Carbon fiber driveshafts reduce vibration at high RPM
- Moderate install — doable in a home garage with some mechanical experience
What Does This Do?
The driveshaft transfers power from the transmission to the rear axle. The stock Challenger uses a heavy two-piece steel unit with a center support bearing. This DSS aluminum one-piece eliminates the center bearing (one less failure point) and saves about 11 lbs of rotating mass. Benefits: faster acceleration from reduced rotational inertia, eliminates center bearing vibrations that some owners report at high speed, and aluminum handles torsional loads better than the two-piece design at high HP. SFI certified for drag racing. Trade-offs: aluminum driveshafts are less weight savings than carbon fiber but significantly cheaper and more durable in daily use. They produce a slightly different sound profile (more metallic 'ring'). An aluminum one-piece is the sweet spot for most builds — you get the reliability of metal with significant weight savings. For all-out drag builds, the carbon fiber option saves even more weight but at 2-3x the cost.
Technical Details
3.5-inch aluminum one-piece driveshaft rated to 1200HP. Eliminates flex and vibration of the OE two-piece unit. SFI certified. Reduces drivetrain loss by 8-10 lbs.
