H&R 71644 20mm Non-Adjustable Rear Sway Bar / Stabilizer Bar

The H&R 71644 is a 20mm non-adjustable rear sway bar engineered to reduce body roll, increase lateral stiffness, and sharpen handling response. A direct bolt-on upgrade over the factory stabilizer bar, it pairs seamlessly with H&R springs, coilovers, performance shocks, and Cup Kits for a fully optimized suspension setup.

Key Features:

• 20mm diameter rear sway bar — a meaningful step up in roll stiffness over the stock bar
• Manufactured from 50CrV4 high-tensile spring steel — stronger and more resilient than standard sway bar materials
• Shot peened and heat treated for enhanced durability and fatigue resistance
• Precision forged ends for accurate fitment and smooth transitional function
• Bent on H&R's proprietary machines for complex, precise curves and a perfect vehicle fit
• Includes H&R urethane/Teflon composite bushings — squeak-free and maintenance-free (no lubrication required)
• Non-adjustable fixed bar design for straightforward installation

The H&R 71644 rear sway bar increases your suspension's roll stiffness — its resistance to body lean in turns — while maintaining ride comfort and dramatically improving cornering control, lateral stability, and grip. Ideal for drivers seeking improved handling without altering ride height or ride quality.
