KYB KG5499 Shock Absorber - Front

KYB Gas-a-Just Front Shock for Ford Aerostar

The KYB Gas-a-Just KG5499 is a front suspension shock absorber built as an OE-style monotube replacement for the Ford Aerostar. It is engineered to restore control, responsiveness, and ride stability for daily driving, towing, and vehicles running larger wheels and tires.

Key Features

• Monotube shock design with separate gas and oil chambers for consistent damping
• Up to 25% more damping performance than original equipment shocks
• Higher gas pressure for quicker steering response and improved control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Dust cover included for added protection
• Designed specifically for the Ford Aerostar front suspension
• R-stop and B-stop design details support proper suspension travel control

Gas-a-Just Product Line Details

KYB Gas-a-Just shocks are built for drivers who need firmer response than a standard OE replacement shock can provide. The monotube construction uses a high-pressure nitrogen gas section and an air-free hydraulic working area, which helps maintain fade-resistant operation and immediate damping response during normal driving and load changes.

This KYB KG5499 front shock absorber cross-references Monroe Shocks & Struts 37060 and Gabriel G63621 for the same application.

Detailed Description

Compatible with 1990-1997 Ford Aerostar front suspension applications, the KYB Gas-a-Just KG5499 is a direct-fit shock absorber for restoring front-end control and ride consistency. It is a strong choice for Ford Aerostar owners looking for a front shock that responds quickly under braking, cornering, and load transfer while maintaining everyday ride comfort. The monotube layout and high gas pressure help the shock react faster than many twin-tube designs, making it well suited for vehicles that work harder than average.

What It Helps Address

• Excessive front-end bounce after bumps or dips
• Reduced steering response and loose handling feel
• Shock fade during repeated suspension movement
• Fluid leakage caused by seal wear
• Ride instability on Ford Aerostar models with added load or larger tires
