Key Features & Benefits

High‑Strength Alloy Construction Robust alloy material resists bending, stress fatigue and deformation. Maintains accurate suspension geometry under daily road loads.

Pre‑Assembled Sealed Ball Joints and Reinforced Bushings Sealed ball joints keep out dust, moisture and road salt to extend service life. Heavy‑duty rubber bushings absorb road shocks and reduce chassis vibration.

Solve Common Front Chassis Faults Eliminate clunking noises on rough roads, sloppy steering feedback, vehicle pulling and irregular tire wear caused by aged original arms and bushings.

Exact Direct Fit, No Modification Required Precision‑machined mounting holes and thread specifications match factory standards. No cutting or drilling required for professional repair shop installation.

Anti‑Corrosion Surface Treatment Protective coating guards against rust, road salt and debris, improving long‑term durability in varied weather conditions.

Installation Note

Professional installation is highly recommended. Four‑wheel alignment must be completed after replacement to adjust camber and caster angles, avoid premature tire wear and guarantee straight‑line driving. Note production date restriction for Audi S4 application.

Warranty

12‑month manufacturer warranty against manufacturing defects. Fitment verification, installation guidance and after‑sales support are available.
