65-78 Chrysler Full Size

The KYB Gas-a-Just shock absorber for 1965–1978 Chrysler full-size vehicles delivers the ride control and durability that classic car owners demand when restoring or maintaining their prized machines. Built by KYB, a manufacturer with decades of suspension engineering expertise, this rear monotube shock is engineered to replace worn dampers and restore proper weight transfer, body control, and handling responsiveness on models spanning the Dodge and Plymouth lineup. Whether you're refreshing a tired restoration or upgrading aging original equipment, this shock addresses the real-world challenge of aging suspension components that lose their ability to manage body roll and maintain consistent tire contact.

This monotube design uses pressurized nitrogen gas to maintain consistent damping force across a wide range of driving conditions—eliminating fade that develops in conventional twin-tube shocks under sustained braking or spirited driving. The steel construction with silver paint finish resists corrosion and blends seamlessly with undercarriage components, while the gas charge prevents aeration and cavitation that can occur in rod-motion cycles. At 4.05 pounds and measuring 20.9 inches in length, the compact footprint and light weight are optimized for the original suspension geometry of full-size Chrysler platforms, ensuring predictable response without requiring additional chassis bracing or frame modifications.

Rear-position installation on 1965–1978 Dodge and Plymouth full-size models requires minimal fitment work when paired with original or OEM-equivalent springs and mounting hardware. Mechanics restoring these platforms appreciate the direct bolt-on compatibility and the improved handling that results from replacing both rear shocks as a matched pair. This shock excels for drivers seeking stock-faithful suspension geometry without expensive coil-over conversions, making it the practical choice for preserving originality while gaining tangible improvements in stability, stopping consistency, and cornering control.
