The Buick Rainier Sway Bar Kit helps the midsize SUV corner flatter by putting the left and right suspension together with a torsion bar that helps resist body lean. In practice, the Sway Bar Kit connects the opposite wheels together so that when one wheel goes higher over a bump or dips when taking a fast turn, the bar twists and pushes the other side to the same height, keeping the body even and the tires gripping evenly. This is a simple but strong steel bar that forms the core of the Sway Bar Kit and is supported by bushings and end links that fix it to the frame and control arms. Earlier models of Buick applied fixed rate bars, but later Rainier versions could be ordered with an adjustable Sway Bar Kit which offers the owner two settings, a softer setting for daily driving comfort or a firmer setting for spirited driving, which changes roll stiffness but not the spring rates. As for the upgrade's benefits to owners of the Rainier, they like the sharper steering response. While the device dramatically improves stability, it can also transfer sharp bumps across the axle so the design is balanced between the thickness of the bars and the type of bushing material to reduce the feel of the waddling on rough pavement. Overall, the Sway Bar Kit is an important part of the suspension system that gives Buick drivers confidence while merging, cornering, or towing.
