What was done to keep all this horsepower from bending up these uni-bodies we have?

 

The DCX LX platform is a full UNIBODY structural design. The front and rear suspension is mounted to an isolated cradle. The cradles are used to increase the strength of the suspension mount areas without having to over design the body structure. The LX front cradle also holds the engine mounts but the transmission crossmember is bolted to the floor pan. The front springs and upper control arms are mounted in the front apron structure. The rear springs along with the shocks are mounted to the inner quarter structure. All of the rear suspension control arms are bolted to the cradle.

Because UNIBODY cars absorb more impact, and lessen the force of impact on a driver, the Challenger has received 5-star crash ratings.
