KYB KG54105 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Toyota T100

The KYB Gas-a-Just KG54105 is a rear suspension shock absorber for 1993-1998 Toyota T100 models. Built as a monotube design, it delivers quicker response and more consistent damping for trucks that carry loads, tow, or run larger wheels and tires.

For Toyota T100 rear suspension service, this KYB Gas-a-Just shock is engineered to add control without sacrificing everyday ride quality. The KG54105 is designed for direct rear fitment on the Toyota T100 and uses a high-pressure gas design to help maintain performance under demanding driving conditions.

Key Features

• Monotube shock absorber design for responsive damping
• Adds up to 25% more damping performance over original equipment shocks
• High-pressure gas and oil separation helps reduce fade from aeration
• Triple chrome plated piston rod helps reduce seal wear
• Designed specifically for Toyota T100 rear applications
• Supports vehicles that work, tow, or use heavier tires and wheels
• Dust cover included

Product Details

The KYB Gas-a-Just line is built around a two-chamber monotube layout. One chamber handles hydraulic response for control, while the gas chamber helps the shock react quickly when road conditions change. That design supports stable handling and more consistent steering response, especially on a Toyota T100 used for hauling or daily driving with added load. Part number KG54105 is a rear shock absorber with E1 upper and lower mounts, 15.67 inches compressed length, 25.31 inches extended length, and 9.64 inches of stroke.

This part cross-references Monroe Shocks & Struts 37101 for the same application.

What It Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control when towing or carrying cargo
• Shock fade during repeated suspension movement
• Loose or delayed steering response from worn rear damping
• Uneven ride quality from aging rear shocks

Installation Notes and Tips

Fits 1993-1998 Toyota T100, rear. Verify mount style, compressed length, extended length, and stroke before installation to confirm proper suspension travel. Inspect related rear suspension components, including bushings and mounts, while replacing the shock absorber. Part number KG54105 is intended for rear placement only on the listed Toyota T100 applications.

Quality Assurance

KYB designs the Gas-a-Just line with a monotube construction that separates gas and oil for consistent damping performance. The triple chrome plated piston rod is used to help reduce seal wear and support long-term operation in demanding suspension service.
