H&R 70643 Sport Sway Bar Kit with Urethane/Teflon Bushings

The H&R 70643 Sport Sway Bar Kit is a precision-engineered suspension upgrade crafted from high-strength 50CrV4 steel alloy — the same specialized spring steel used across H&R's world-renowned suspension lineup. Formed on proprietary H&R machines, each bar is shaped to exact dimensional tolerances, delivering an exceptional level of fitment accuracy and consistent on-road performance.

Key Features:

• 50CrV4 High-Tensile Steel Construction — Stronger and more resilient than standard OEM sway bars, with consistent material properties for smooth, predictable transitions in roll stiffness
• Cold-Formed and Heat-Treated — Each bar is cold-formed, heat-treated, and shot-peened for increased surface hardness, long-term durability, and dimensional accuracy
• Precision Forged Bar Ends — Smooth, machined-like forged ends that, on applicable configurations, offer multiple mounting points for adjustable stiffness tuning
• Exclusive Urethane/Teflon Composite Bushings — Proprietary bushings with a molded-in fabric-like liner that eliminates squeaking and requires absolutely no lubrication or maintenance
• Powder-Coated Finish — Durable powder coating provides long-lasting corrosion resistance and a clean, professional appearance
• ISO 9001 Certified, Made in Germany — Manufactured entirely in-house at H&R's certified German facility and subject to rigorous quality control testing before approval

The H&R 70643 sway bar kit reduces body roll and improves lateral stability and cornering grip without compromising everyday ride comfort. It pairs seamlessly with H&R springs, coil-overs, and Cup Kits for a complete, balanced suspension system.
