Audi S4 Shock - Rear - KYB - Gas-A-Just - 2018-2025. Precision KYB monotube rear shock designed to tighten response and keep your S4 planted through changing road conditions.
The Gas-A-Just uses a high-pressure nitrogen charge and monotube architecture to deliver consistent, fade-resistant damping. It replaces worn factory shocks to restore control, limit excessive body movement, and sharpen steering feedback without harshness. Engineered as a direct bolt-in for the rear of the 2018-2025 Audi S4 at stock ride height, it works well with OE or mild sport springs for an enthusiast-friendly setup.
