H&R 71257 Sport Rear Sway Bar Kit 22mm Adjustable

The H&R 71257 is a 22mm adjustable rear sport sway bar kit engineered to reduce body roll, increase lateral stiffness, and sharpen handling performance. Designed as a direct-fit upgrade over the factory stabilizer bar, this kit delivers a noticeable improvement in cornering control and overall suspension response without compromising everyday ride quality.

50CrV4 Steel Construction: Each H&R Sport Sway Bar is cold-formed from a specialized (hf) 50CrV4 high-tensile steel alloy—one of the strongest spring steel grades available—ensuring superior resilience and long-term durability over standard sway bars.

Key Features:

• 22mm rear bar diameter — increased over OEM for greater roll stiffness and improved cornering grip
• Adjustable forged ends — smooth, machined-like precision forged bar ends with multiple mounting positions for fine-tuning suspension stiffness
• Shot-peened and heat-treated — H&R's exclusive finishing process increases surface hardness, dimensional accuracy, and service life
• Powder-coated finish — corrosion-resistant coating for lasting durability and clean appearance
• Urethane/Teflon composite bushings included — proprietary maintenance-free bushings with a molded-in fabric liner that eliminates squeaking and requires zero lubrication
• 100% Made in Germany — manufactured in H&R's ISO 9001-certified facility with in-house quality control testing on every unit

The H&R 71257 sway bar kit pairs seamlessly with H&R springs, coilovers, and cup kits to build a complete, balanced performance suspension system. Installation is straightforward with no cutting or modification required—simply bolt in and drive.
