H&R 72839 Front & Rear Sport Sway Bar Kit - 25mm Front / 18mm Rear

The H&R 72839 Sport Sway Bar Kit delivers a complete front and rear anti-roll bar upgrade engineered for drivers seeking sharper handling and reduced body roll without compromising everyday ride comfort. This kit includes a 25mm front sway bar and an 18mm rear sway bar, precision-matched to work together for a balanced, performance-tuned suspension setup.

H&R Sport Sway Bars are cold-formed and heat-treated, crafted from a specialized 50CrV4 steel alloy — the highest tensile strength material available — and shot-peened for increased durability. Each bar features smooth, machined-like forged seamless ends that, on applicable vehicles, allow for multiple stiffness adjustment positions, giving you a customizable level of performance and precision.

Key Features:

• Increases suspension roll stiffness to reduce body roll in corners
• Improves lateral stability, cornering grip, and turn-in response
• 25mm front bar and 18mm rear bar included as a matched set
• Cold-formed and heat-treated 50CrV4 high-tensile steel construction
• Shot-peened finish for enhanced durability and dimensional accuracy
• Forged, seamless bar ends with adjustable stiffness positions (vehicle dependent)
• Manufactured at H&R's ISO 9001 certified facility in Germany

Exclusive Urethane/Teflon Composite Sway Bar Bushings Included: This kit comes with H&R's proprietary sway bar bushings — available exclusively with H&R Sport Sway Bar kits. The special urethane/Teflon composite construction prevents squeaks and eliminates the need for lubrication, resulting in a maintenance-free, precision fit.

The H&R 72839 sway bar kit is a direct bolt-on upgrade that improves handling balance without requiring a lowering spring or shock change, making it an ideal standalone performance suspension enhancement.
