Your vehicle will benefit from this X-Brace by drastically decreasing chassis flex, and increasing the rigidity of the sub frame. Your vehicle will feel much tighter at higher speeds and will react in a tighter fashion in quick turn situations. The Challenger is notorious “wheel shake” at 70-80MPH. This will also be reduced.
Our X-Brace is mounted directly under the transmission, with plenty of ground clearance for vehicles using stock cats and exhaust manifolds, most long-tube header systems and/or stock exhaust manifolds with hi-flow cats.
Using this X-Brace in conjunction with any or all of our other suspension components will really allow you to take advantage of a well-handling machine.
