BMR Suspension designed their challgenger trailing arms to work well in street performance, drag race, and road race applications. The stock trailing arms flex under cornering loads giving you inconsistent handling characteristics. Combine this with soft bushings that have massive amounts of deflection and you’re left with poor performance. The heavy-duty construction eliminates trailing arm flex, giving you much improved repeatability on the street, starting line, or in the corners. BMR’s polyurethane bushings are designed to be compliant enough to give you a comfortable ride and absorb NVH, while remaining firm enough to stand up to high loads of any performance environment. The bushings easily handle the high compression loads of hard launches and hard acceleration, yet offer plenty of articulation for great handling. These are the perfect upgrade for the enthusiast looking to improve performance at an affordable price, while maintaining acceptable NVH levels and ride quality. When performance is a must, rely on BMR Suspension!
