Product Description

The H&R 72462-2 Sport Sway Bar Kit is a complete front and rear anti-roll bar upgrade designed specifically for xDrive (AWD) variants of BMW's G20 3-Series Sedan and G22/G23 4-Series Coupe and Convertible platforms. This performance set features a 26mm non-adjustable solid front bar paired with a 19mm non-adjustable solid rear bar, both precision-formed from 50CrV4 high-tensile steel alloy - the highest tensile strength available in the industry. Each bar is cold-formed, heat-treated, and shot-peened with precision forged seamless ends, ensuring exceptional strength, durability, and dimensional accuracy. H&R's proprietary bending machines produce perfectly matched complex curves for precise OEM-like fitment. The kit dramatically reduces body roll while increasing lateral stiffness, cornering grip, and steering response without sacrificing ride comfort. H&R's exclusive urethane/Teflon composite bushings feature a molded-in fabric-like material that eliminates squeaks and requires no lubrication for maintenance-free operation. The perfect complement to H&R springs, coilovers, cup kits, and performance shocks. All H&R products are 100% manufactured in Germany at their ISO9001 certified facility, TUV approved, and must pass rigorous quality control testing before approval.
