H&R 70431-25 Front Adjustable Sway Bar 25mm Sport Series

The H&R 70431-25 is a 25mm front adjustable sport sway bar engineered to reduce body roll, increase lateral stiffness, and sharpen handling response — all without compromising everyday ride comfort. Featuring a two-hole adjustable bar end design, this stabilizer bar allows fine-tuning of suspension roll stiffness to dial in the precise balance of oversteer and understeer for your driving style.

Key Features:

• 50CrV4 alloy steel construction — a premium chromium-vanadium spring steel offering the highest tensile strength available for superior durability and resilience
• Cold-formed and heat-treated manufacturing process ensures consistent geometry and long-term structural integrity
• Shot-peened finish increases surface hardness and fatigue resistance for extended service life
• Precision forged seamless bar ends with two adjustment holes for stiffness tuning
• Exclusive urethane/Teflon composite bushings with a molded-in fabric layer — maintenance-free, lubrication-free, and squeak-free
• Powder-coated finish for corrosion resistance and lasting appearance
• 100% manufactured in Germany at H&R's ISO 9001-certified, TÜV-approved facility

H&R sway bars are formed on proprietary bending machines designed in-house, allowing for the complex geometry and tight tolerances required for a precise OEM-style fit. Each bar is dimensionally verified before leaving the factory. The included urethane/Teflon bushings are unique to H&R and require no greasing — eliminating the squeaks and maintenance associated with standard rubber bushings.

This sway bar pairs perfectly with H&R sport springs, coilovers, and cup kits for a complete handling upgrade. H&R backs this sway bar with a lifetime warranty against manufacturer defects for the original owner; bushings are warranted for one year.
