H&R 70458 Sport Sway Bar Kit Front Stabilizer Bar with Urethane Bushings

The H&R 70458 Sport Sway Bar Kit is a precision-engineered front stabilizer bar designed to reduce body roll, increase lateral stiffness, and sharpen cornering performance — all without sacrificing ride comfort. Built for drivers who want improved handling dynamics without lowering their vehicle, this kit delivers a measurable upgrade over factory sway bar components.

Key Features:

• 50CrV4 Spring Steel Construction: Cold-formed from a specialized 50CrV4 chromium-vanadium steel alloy — the highest tensile strength material available — for superior resilience and durability over stock and competitive alternatives.
• Precision-Formed on Proprietary H&R Machinery: Each bar is bent on machines designed exclusively by H&R, producing consistent, complex curves that guarantee an exact, application-specific fit.
• Shot-Peened and Heat-Treated: Every sway bar undergoes heat treatment and shot-peening to increase surface hardness, improve fatigue resistance, and extend service life.
• Forged Bar Ends with Adjustability: Smooth, machined-like forged ends allow for stiffness adjustability on select applications, providing a customizable handling setup.
• Exclusive Urethane/Teflon Composite Bushings Included: H&R's proprietary bushing compound eliminates squeaking and requires zero lubrication or maintenance — just install and drive.
• Powder-Coated Finish: A durable powder coat protects against corrosion and provides a clean, long-lasting appearance.
• 100% Made in Germany: Manufactured at H&R's ISO 9001-certified facility in Germany, with rigorous in-house quality control testing on every unit.

The H&R 70458 is a direct complement to H&R springs, coilovers, and cup kits, making it an ideal upgrade for enthusiasts building a complete H&R suspension system. No cutting, drilling, or modifications required — a true bolt-in performance upgrade.
