KYB KG5514 Shock Absorber - Front or Rear

KYB Gas-a-Just Shock Absorber KG5514

The KYB Gas-a-Just KG5514 is a monotube suspension shock absorber built for vehicles that work harder than a standard commuter setup. It delivers quicker response, firmer control, and fade-resistant damping for heavy-duty use, towing, and larger wheel-and-tire packages.

Gas-a-Just Performance Line

KYB Gas-a-Just shocks use a monotube design with separate gas and oil chambers for consistent damping and immediate reaction to suspension movement. This line is aimed at drivers who want more control than a twin-tube OE-style shock can provide, especially on applications like Chevrolet P30 rear motorhome chassis, GMC P3500 rear motorhome, Ford Pinto rear, Mercury Bobcat rear, and Ford Thunderbird front.

• Adds up to 25% more damping performance over original equipment shocks
• High-pressure monotube construction separates gas and oil for fade-free operation
• Designed for heavy-duty trucks, towing, and larger, heavier tires and wheels
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response and suspension control
• Supports electronic safety systems by helping the suspension operate as the vehicle manufacturer intended

Detailed Product Overview

Part number KG5514 is a rear or front suspension shock absorber, depending on application, with a compressed length of 8.74 inches, extended length of 13.86 inches, and 5.12 inches of stroke. It uses S1 upper and lower mounts and includes a dust cover. The monotube design provides an air-free hydraulic working area for responsiveness and a separate high-pressure nitrogen chamber for consistent ride quality during normal driving and added performance when load or road conditions change. This part cross-references Gabriel 82026 for the same application.

What This Shock Helps Address

• Excessive body motion on heavy-duty or loaded vehicles
• Reduced damping control from worn OE shocks
• Shock fade caused by aeration during repeated suspension movement
• Loose steering feel on vehicles with larger tires and wheels
• Ride instability on motorhome chassis and older performance applications
