Oh what a difference a lower center of gravity makes during acceleration, braking, and cornering. The McGaughy's 2-4.5-inch lowering kit was an instant improvement in both the SRT's appearance and handling performance. The lowered stance not only looks cool but made for a firmer ride with less body roll during cornering and nose-diving while braking. The additional McGaughy's rear helper bags not only beefed up the rear suspension with an increased payload, but they also helped eliminate wheel hop during aggressive acceleration.
