Now you can push that old car into a corner and expect stabile, predictable, smooth cornering performance. The MuscleBar is constructed out of a CNC bent, 1.5-inch by 0.250-inch wall main bar to minimize body roll and equalize traction on all four wheels to improve cornering performance. It is a true bolt-on installation using OEM attachment points and features a Posi-link linkage system that maintains engagement between the sway bar and the control arm at all times.
