Upgrades include strengthened gears, improved clutch packs, and a recalibrated control system. This ensures that the transmission can withstand the brutal demands of repeated launches and high-speed runs. The eight-speed design also allows for close gear ratios, which keeps the engine in its optimal power band for maximum acceleration. The transmission's adaptive control system continuously learns the driver's behavior and adjusts shift points accordingly, providing a personalized driving experience. Whether you're cruising on the street or tearing up the drag strip, the transmission seamlessly adapts to your driving style. Additionally, the transmission is equipped with features like paddle shifters and a manual mode, giving the driver full control over gear selection. This allows for precise control during performance driving and enhances the overall driving experience. The combination of strength, precision, and adaptability makes the TorqueFlite 8HP90 transmission the perfect match for the Demon 170's high-performance engine.

Driveshaft

The driveshaft is a critical link in the drivetrain, connecting the transmission to the rear axle. In the Demon 170, the driveshaft has been significantly upgraded to handle the extreme torque loads. It is made from a stronger, more durable material than the standard Challenger driveshaft. This ensures that it can withstand the immense twisting forces generated by the engine and transmission. The driveshaft is also designed to minimize vibrations and reduce noise, providing a smoother and more refined driving experience. Its robust construction and precise engineering contribute to the overall reliability and performance of the Demon 170's drivetrain. The driveshaft's importance cannot be overstated, as it is responsible for transmitting power from the transmission to the rear axle, ultimately driving the wheels and propelling the car forward. Without a strong and reliable driveshaft, the Demon 170's incredible power would be useless. Therefore, the upgrades to the driveshaft are a crucial component of the overall drivetrain enhancements.

Rear Axle

The rear axle is where the power finally meets the wheels. The Demon 170 features a heavy-duty rear axle with a 3.09 gear ratio. This ratio is optimized for maximum acceleration, allowing the Demon to launch off the line with incredible force. The rear axle also includes a limited-slip differential, which helps to distribute power evenly to both rear wheels. This is essential for maintaining traction and preventing wheel spin, especially during hard launches. The axle shafts themselves are also strengthened to withstand the immense torque loads. The entire rear axle assembly is designed to be incredibly durable and reliable, ensuring that it can handle the rigors of repeated drag strip runs. Furthermore, the rear axle housing is reinforced to prevent flexing and maintain proper alignment under extreme conditions. This attention to detail ensures that the rear axle can consistently deliver power to the wheels, contributing to the Demon 170's blistering acceleration and impressive performance. The combination of a strong housing, durable shafts, and a limited-slip differential makes the rear axle a crucial component of the Demon 170's drivetrain.

Suspension

While not strictly part of the drivetrain, the suspension plays a crucial role in putting the power down effectively. The Demon 170 features an adjustable suspension system that allows drivers to fine-tune the car's handling for different conditions. This includes settings for drag racing, street driving, and track use. The suspension system also includes adaptive dampers, which automatically adjust to changing road conditions.

The adjustable suspension is a key component in maximizing the Demon 170's performance, allowing drivers to tailor the car's handling to their specific needs. The suspension system also works in conjunction with the car's electronic stability control system to maintain traction and prevent wheel spin. This ensures that the Demon 170 remains stable and controllable, even under the most extreme acceleration.

Wheels and Tires

Finally, the wheels and tires are the point of contact with the road. The Demon 170 comes standard with lightweight wheels and specially designed tires. These tires are designed to maximize grip and provide optimal traction. The rear tires are wider than the front tires, which helps to put more power down to the ground. The tires also feature a special compound that provides excellent grip in both dry and wet conditions. The combination of lightweight wheels and high-performance tires is essential for maximizing the Demon 170's acceleration and handling. The wheels are designed to be both strong and lightweight, reducing unsprung weight and improving overall performance.
