KYB KG5614 Shock Absorber - Front

KYB Gas-a-Just Front Shock for Frontier

The KYB Gas-a-Just KG5614 is a front suspension shock absorber built for 2003-2004 Nissan Frontier applications. This monotube design is engineered for quicker response, firmer control, and consistent damping in daily driving, towing, and heavier-duty use.

Gas-a-Just Line Overview

KYB Gas-a-Just shocks use a high-pressure monotube layout with separate gas and oil chambers. That design helps maintain fade-free operation, improves steering response, and adds damping performance beyond a typical OE twin-tube shock when the vehicle is carrying more load or running larger tires and wheels.

Key Features

• Part number KG5614 for front suspension service
• Fits 2004 Nissan Frontier, front
• Fits 2003 Nissan Frontier, front, from 3/2003
• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for consistent response
• High-pressure nitrogen gas helps reduce fade during repeated suspension movement
• Triple chrome plated piston rod helps reduce seal wear
• Dust cover included
• Designed specifically for Nissan Frontier front applications

Detailed Description

KYB KG5614 is a front shock absorber for Nissan Frontier trucks that need more controlled suspension response than a standard OE-style replacement. The Gas-a-Just line is tuned for vehicles that work harder, tow, or run heavier wheel and tire setups, while still maintaining a comfortable ride during normal driving. The monotube design and high gas pressure help the shock react quickly to steering and road inputs, which can improve front-end control and stability.

This part cross-references Monroe Shocks & Struts (e.g., 37077) for the same application.

What It Helps Address

• Excessive front-end bounce after bumps
• Reduced steering response on worn suspension
• Shock fade during repeated load changes
• Loss of control with heavier tires and wheels
• Uneven damping from aging front shocks

Installation Notes and Tips

Compatible with 2004 Nissan Frontier, front, and 2003 Nissan Frontier, front from 3/2003. Verify mount style and compressed/extended length before installation: compressed length 8.66 in., extended length 12.79 in., stroke length 4.13 in. Lower mount type is E2(12X32) and upper mount type is S1. Inspect related suspension components, tire condition, and mounting points before replacing the shock.

Quality Assurance

KYB designs Gas-a-Just shocks as monotube performance dampers with separate gas and oil chambers for consistent operation and reduced fade. The KG5614 uses a triple chrome plated piston rod to help reduce seal wear and support long-term sealing performance.
