The secret of the R.E. long-arm kit that makes it perform well is the positioning of the upper and lower control arms and mounts. Designed specifically to enhance vehicle dynamics both on and off pavement, the math used here makes all the difference in how the long-arm kit controls pitch, yaw, and sway. The correct amount of anti-squat and carefully calculated suspension geometry help to minimize body roll and improve on-road handling dynamics, while the range of motion is maximized to aid articulation. Note how flat the bellypan is once installed. No protruding bolt heads to get caught on rocks-just flush, flat, and smooth.
