BMR Differential Bushing Kit 05-14
3 link suspensions place excessive loads on the upper link bushings. In the '05, two bushings are responsible for handling the same torque load that 4 bushings had done before. Additionally, these bushings are subjected to more "twist" than before since the rear end can better articulate as a 3 link design. In order to allow free articulation, the OE rearend bushing is designed to flex. This flex is great for handling but under straight line acceleration, it contributes to wheelhop and inconsistant launch characteristics.
