Dodge Demon Teases Its Hardened Parts

Dodge is giving an inside look at the driveline upgrades heading to the Challenger SRT Demon.

The latest video in a series of teasers leading up to the sports car’s debut on April 11 puts the focus on the upgraded prop shaft, differential housing and 41-spline half shafts. According to the American automaker, the prop shaft increases torque capacity by 15 percent, thanks to the use of high-strength steel, a 20-percent increase in tube thickness and heat-treated stub-shafts. The upgraded differential housing has 30 percent increased torque capacity through the use of heat-treated A383 aluminum and a higher strength gear set material that has been shot-peened to increase durability and reduce residual stresses.

Lastly, the upgraded 41-spline half shafts delivers 20-percent increased torque capacity due to the use of increased diameter high-strength low alloy steel and 8-ball joints that improve torque capacity while reducing operating temperatures by more than 86-degrees Fahrenheit.

From there, engineers went digital to tackle on wheel hop, which happens when tires quickly slip and regain traction at launch, rapidly storing up and releasing energy in the driveline. The American automaker claims the SRT Demon’s Launch Assist uses the wheel speed sensors to watch for signs that the tires are slipping/sticking, and once detected the control module momentarily reduces engine torque to maximize traction. Most importantly, all of this happens without the driver having to lift off the gas pedal.

Dodge also shows off a new four-point harness bar that will be available through Speedlogix to use while at the track. Since the rear seat is deleted on the Demon, access to the mounting points is made easily accessible so customers can install the bar without cutting or drilling.
