H&R 71987 21mm Adjustable Rear Sway Bar Kit

The H&R 71987 is a 21mm adjustable rear sway bar kit engineered to reduce body roll, increase lateral stiffness, and sharpen handling response. Designed for performance-minded drivers who want improved cornering dynamics without sacrificing everyday ride comfort, this sway bar is a direct-fit upgrade over the factory stabilizer bar.

Key Features:

• 50CrV4 Spring Steel Construction: Cold-formed from a specialized 50CrV4 chromium-vanadium steel alloy — the highest tensile strength available — for superior strength, resilience, and long-term durability
• 5-Position Adjustability: Precision forged ends with multiple end-link mounting points allow fine-tuning of rear roll stiffness to dial in oversteer or understeer balance to suit your driving style
• Shot-Peened & Heat-Treated: Each bar is heat-treated and shot-peened for increased surface hardness, enhanced fatigue resistance, and dimensional accuracy
• Powder Coated Finish: A durable powder coat protects against corrosion and provides a clean, long-lasting appearance
• Proprietary Urethane/Teflon Composite Bushings Included: H&R's exclusive bushing design features a molded-in fabric-like material that permanently eliminates squeaking and requires zero lubrication or maintenance
• Precision Bent on H&R Proprietary Machines: Formed on specialized machinery designed in-house by H&R to ensure exact fitment and consistent geometry for every application

Like all H&R suspension components, the 71987 sway bar is 100% manufactured in Germany at H&R's ISO 9001-certified facility, with every bar passing rigorous quality control inspection before leaving the factory. H&R sway bars pair perfectly with H&R springs, coilover systems, performance shocks, and Cup Kits for a comprehensive suspension upgrade. Lifetime warranty against manufacturer defects to the original owner; bushings warranted for one year.
