KYB KG5435 Suspension Shock Absorber - Front

KYB Gas-a-just Shock Absorber KG5435

The KYB Gas-a-just KG5435 is a monotube suspension shock absorber built for trucks and other vehicles that need firmer control under load. It uses separate gas and oil chambers for quick response, reduced fade, and consistent damping during demanding driving.

Gas-a-just Product Line

KYB Gas-a-just shocks are part of KYB’s performance-oriented monotube line. The design adds damping over OE-style shocks for vehicles that work, tow, or run larger, heavier tires and wheels, while still maintaining a controlled ride in normal driving.

Key Features

• Adds up to 25% more damping performance over original equipment shocks
• Monotube construction separates gas and oil for fade-free operation and fast response
• High-pressure nitrogen gas helps the shock adjust instantly to changing road conditions
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are engineered for heavy-duty truck use
• Dust cover included
• B-stop and R-stop included in the design

Detailed Description

KYB KG5435 uses an air-free hydraulic working area for control and a high-pressure gas chamber with a floating piston for responsiveness. That layout helps maintain steering feel and suspension control when the vehicle is carrying weight, towing, or running larger wheels and tires. For drivers searching for a KYB Gas-a-just shock absorber for truck suspension repair, KG5435 delivers a direct-fit solution focused on damping consistency and road control. This part cross-references Monroe Shocks & Struts (e.g., 555045) for the same application.

What It Helps Address

• Excessive bounce after bumps or dips
• Reduced control when towing or hauling
• Shock fade from heat and aeration during repeated suspension movement
• Loose steering response on heavier-duty vehicles
• Wear related to leaking shock seals and piston rod contamination

Installation Notes and Tips

Verify compressed length, extended length, stroke length, and upper/lower mount type before installation. KG5435 measures 12.01 inches compressed, 16.14 inches extended, and 4.13 inches of stroke, with E2(14.6x41) upper and lower mounts. Confirm vehicle-specific suspension position and inspect related bushings, mounts, and hardware condition during replacement. Search terms such as KYB KG5435 shock absorber for truck suspension, heavy-duty rear shock replacement, and KYB Gas-a-just monotube shock for towing applications are commonly used when matching this part.

Quality Assurance

KYB designs Gas-a-just shocks with monotube construction and high-pressure gas separation to maintain consistent damping performance. The ultra-smooth triple chrome plated piston rod is used to help reduce seal wear and support long-term operation in demanding suspension service.
