This Hellwig 7634 1 1/8 inch diameter Rear Sway Bar is an ideal suspension upgrade to improve handling performance and to control side to side leaning or sway. Using mounting points on both the driver and passenger side at or near the Rear axle, the sway bar applies a torsional effect to the suspension. When your GMC Sierra 1500 begins to lean to one side, the Hellwig Sway Bar will apply pressure to the opposite side to resist the transfer of weight. This keeps weight more firmly distributed to all four tires to stay more level with the road. Sway Bars improve cornering traction, turning capabilities and reduce body roll for overall safer driving conditions making them a perfect upgrade for your GMC Sierra 1500 4wd & 2wd.
