63-76 Dart Rear

The KYB Gas-a-Just 63-76 Dart Rear shock absorber is a proven monotube gas-charged suspension component engineered for Dodge and Plymouth compact cars from 1963 through 1976. This rear shock delivers consistent damping performance and vehicle control for daily drivers, weekend cruisers, and restoration projects seeking OEM-quality replacements or performance upgrades. Whether you're refreshing aging suspension geometry or maintaining ride quality on a classic, this KYB offering provides the reliability mechanics and enthusiasts trust across decades of automotive service.

Built with a steel monotube body and silver paint finish, the Gas-a-Just design uses pressurized nitrogen gas to prevent aeration and maintain stable damping characteristics under sustained braking, cornering, and load changes. The monotube construction allows for a more compact footprint while improving heat dissipation—critical for extended driving sessions where traditional twin-tube shocks lose responsiveness. The gas charge maintains consistent pressure throughout the shock's travel, eliminating the fade that plagued older hydraulic-only designs and ensuring predictable suspension behavior mile after mile.

Mechanics and Dart owners upgrading 1963–1976 Dodge Dart and Plymouth models benefit from bolt-on simplicity and immediate improvement in rear-end control and bump compliance. This rear-position shock pairs seamlessly with front shocks to create balanced suspension geometry, reducing body roll and improving cornering stability on street applications. Each shock is sold individually, so verify your suspension setup and purchase the matching pair for proper performance. The 21.35-inch length and compact 3.25-inch diameter ensure fitment within OEM mounting locations without modification.
