The Dodge Demon’s (Drive)line of Defense

We all know that adding horsepower is a great way to start breaking things. Everyone’s first thought is to fortify the motor, often leaving the drivetrain to figure it out at the strip. With great horsepower comes great responsibility, and a part of that is in ensuring the driveline can handle tire-rippling launches while keeping the factory warranty minty on your 2018 Dodge Challenger SRT Demon.

To start, the driveshaft has 15 more torque capacity than the Hellcat, utilizing high-strength steel with 20-percent thicker wall thickness. The differential is also able to withstand 30-percent more torque than that same Hellcat, with a shot-peened, heat-treated A383 cast aluminum housing. Lastly, the 41-spline half-shafts are have been fortified by a good 20-percent, with larger diameter axle shafts and 8-ball CV joints keeping the family together.

But as we’ve mentioned before, hardware is only half the battle — The SRT Demon will have an industry-first wheel hop control, an advanced launch control system that looks specifically for the slipping-and-sticking shock loads that’ll rattle even those nitro lawn darts at the NHRA loose. Not only does this aid in starting line traction, but preventing wheel hop will save the driveline a harsh beating if the tires shake.
