The KYB Gas-a-Just rear shock for Chrysler 300 AWD (2011–2013) is an OE-style monotube replacement intended to restore factory ride and control with added responsiveness. It uses an air-free hydraulic valve area plus a high-pressure nitrogen chamber and floating piston to preserve comfort in daily driving and provide instant response under demand. KYB also recommends new strut mounts (part SM5533) to reduce noise and vibration.
