KYB KG4511 Shock Absorber - Front

KYB Gas-a-Just Front Shock Absorber

The KYB Gas-a-just KG4511 is a front suspension shock absorber built for classic Ford and Mercury applications that need firmer control and consistent damping. Its monotube design separates gas and oil for quick response and reduced fade, making it a strong choice for vehicles with added load, towing demands, or larger tires and wheels.

Fits 1971-1980 Ford Pinto, front. Fits 1975-1980 Mercury Bobcat, front. This part cross-references Monroe Shocks & Struts (e.g., 32118) for the same application.

Gas-a-Just Product Line

KYB Gas-a-just shocks are engineered as monotube dampers with a high-pressure nitrogen gas chamber and an air-free hydraulic working area. That layout gives the KG4511 fast steering response, stable ride control, and fade-resistant performance compared with a traditional twin-tube design.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction for instant response and consistent control
• High-pressure gas and oil separation for fade-free operation
• Triple chrome plated piston rod to reduce seal wear and fluid leakage
• Designed for classic Ford cars, including Ford Pinto and Mercury Bobcat front suspension applications
• Supports vehicles that work, tow, or run heavier tires and wheels
• Dust cover included
• B-stop and R-stop features included

What This Shock Absorber Helps Address

• Excessive front-end bounce over bumps and uneven pavement
• Reduced steering response during braking and cornering
• Shock fade from heat and aeration during repeated suspension movement
• Premature seal wear related to fluid leakage
• Loss of control on classic Ford Pinto and Mercury Bobcat front suspension setups

Installation Notes and Tips

Verify compressed length, extended length, and mount style before installation: compressed length 8.58 in., extended length 10.82 in., stroke length 2.24 in. Lower mount type is E2 (11.1 x 86.2) and upper mount type is S1. Confirm front position fitment for your specific Ford Pinto or Mercury Bobcat model year before ordering.

Quality Assurance

KYB designs Gas-a-just shocks with a monotube layout that separates gas and oil for stable damping and quick response. The KG4511 is built to support suspension performance in classic Ford applications while helping electronic safety systems operate as the vehicle manufacturer intended.
