- High-pressure monotube design: separates the gas and oil for fade-free operation and instant response.
- Two working chambers: an air-free hydraulic piston and valve area for control, plus a high-pressure nitrogen area with a floating piston for a comfortable ride and performance on demand.
- Triple chrome-plated piston rod: an ultra-smooth surface that reduces seal wear, since leaking fluid can cause shock failure.
- Extra damping: higher gas pressure improves steering response, and KYB rates the Gas-a-just to add up to 25% more damping over original-equipment shocks — with components and valving designed specifically for Mopar muscle cars.
This is a front-position shock, sold individually; replacing both front shocks as a pair is recommended for balanced ride and handling.
