KYB KG4510 Shock Absorber - Front

KYB Gas-a-just KG4510 Front Shock Absorber

The KYB Gas-a-just KG4510 is an OE-style monotube shock absorber built to restore front suspension control on classic Mopar muscle cars. It is engineered for responsive damping, stable steering feel, and consistent performance during normal driving and harder use.

Key Features

• Monotube design separates gas and oil for fade-resistant operation and quick response.
• Provides up to 25% more damping performance than original equipment shocks.
• High-pressure nitrogen gas chamber adds control when the vehicle is worked harder or fitted with larger, heavier tires and wheels.
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage.
• Designed specifically for Mopar muscle car applications.
• Dust cover included for added protection.

Product Details

The Gas-a-just line is KYB’s monotube shock absorber family for drivers who want firmer control than a conventional twin-tube design. The KG4510 uses two separate working chambers: an air-free hydraulic section for precise damping and a high-pressure nitrogen gas section with a floating piston for immediate response. That layout helps maintain consistent front-end control on a Dodge Challenger or Dodge Charger, especially when suspension load, tire size, or road conditions demand more from the shock.

This part cross-references Monroe Shocks & Struts 32022 for the same application.

What It Helps Address

• Excessive front-end bounce after bumps
• Loose or delayed steering response
• Reduced damping control with heavier wheels and tires
• Shock fade during repeated suspension movement
• Fluid leakage caused by seal wear

Installation Notes

Fits 1970-1974 Dodge Challenger, front. Fits 1966-1972 Dodge Charger, front. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify compressed length, extended length, and mount style before installation: compressed length 10.04 in., extended length 15.75 in., stroke length 5.71 in., lower mount E2 (11.1 x 32), upper mount S1.

Quality Assurance

KYB designs the Gas-a-just line as an OE monotube replacement to restore original suspension capability while improving damping response. The KG4510 is built with a high-pressure monotube construction and a chrome piston rod to support consistent operation in front suspension service.
