KYB Gas-A-Just Monotube Rear Shock Absorber for Select 1962-1978 Chrysler, Dodge, and Plymouth (KG5512)

Fits select 1962-1978 Chrysler, Dodge, and Plymouth models, including 300, Challenger, Charger, Coronet, Barracuda, Road Runner, and Fury.

The KYB Gas-A-Just is a high-pressure monotube shock absorber designed to provide significantly more control and quicker response than standard twin-tube designs. By using two separate working chambers—an air-free hydraulic area and a high-pressure nitrogen gas chamber with a floating piston—this shock eliminates aeration and fluid foaming. This ensures consistent, fade-free damping performance even during spirited driving or under heavy loads.

• Monotube Performance: High-pressure gas charge provides instant adjustment to road conditions and driver input.
• Anti-Aeration Design: Floating piston separates nitrogen gas from hydraulic fluid to prevent cavitation and performance fade.
• Improved Handling: Restores original damping rates to support steering response, body control, and electronic safety systems.
• Heavy-Duty Build: Features a seamless working cylinder and multi-lip seals for increased durability and leak resistance.
