H&R 71824 Sport Sway Bar Kit 21mm Adjustable Rear Anti-Roll Bar

The H&R 71824 Sport Sway Bar Kit is a performance-engineered, 21mm two-position adjustable rear anti-roll bar designed to reduce body roll, sharpen cornering response, and improve lateral stability — all without compromising everyday ride comfort. Built on H&R's proprietary bending machines in Germany, this sway bar delivers a precise, factory-quality fit combined with measurable performance gains over the stock unit.

Key Features:

• 21mm diameter with 2-way adjustable end link mounting positions for fine-tuning roll stiffness to suit your driving style
• Forged from 50CrV4 chromium-vanadium spring steel — the highest tensile strength alloy available for sway bar applications
• Cold-formed and heat-treated construction with shot-peened finish for increased surface hardness, fatigue resistance, and long-term durability
• Smooth, machined-like forged seamless bar ends for precise geometry and strength at the critical attachment points
• Includes H&R exclusive Urethane/Teflon composite bushings — no lubrication required, no squeaking, no maintenance
• Powder-coated finish for corrosion resistance and lasting appearance
• Manufactured at H&R's ISO 9001-certified facility in Germany and TÜV certified for quality assurance

Each H&R Sport Sway Bar kit is engineered to increase your suspension's roll stiffness — its resistance to lean in corners — while maintaining balanced handling characteristics. The included proprietary urethane/Teflon bushings eliminate the squeaks and maintenance demands of traditional rubber bushings, making installation clean and trouble-free. H&R 71824 pairs seamlessly with H&R springs, coilovers, and cup kits for a complete suspension upgrade.
