KYB 553360 Shock Absorber - Front

KYB Gas-a-just Front Shock for Tacoma

The KYB Gas-a-just 553360 is a front suspension shock absorber for 1999-2004 Toyota Tacoma models. Built as a monotube design, it delivers quicker response and more consistent damping than a traditional twin-tube shock, making it a direct choice for Tacoma trucks that work, tow, or run larger tires and wheels.

Key Features

• Monotube shock absorber design for responsive front suspension control
• Up to 25% more damping performance than original equipment shocks
• High-pressure gas and oil separation for fade-free operation
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Higher gas pressure improves steering response
• Dust cover included
• Engineered specifically for Toyota Tacoma applications

Product Details

KYB Gas-a-just shocks use two separate working chambers: an air-free hydraulic area for control and a high-pressure nitrogen gas chamber with a floating piston for added performance on demand. That design helps the shock react quickly during normal driving while maintaining consistent damping under heavier loads and more demanding road conditions. For front-end service on a Toyota Tacoma, KYB 553360 is a practical OE-style upgrade that supports suspension stability, braking consistency, and steering feel.

This part cross-references Monroe Shocks & Struts 37111 for the same application.

What It Helps Address

• Front-end bounce or excessive body movement
• Reduced steering response on rough or uneven roads
• Shock fade during repeated suspension compression
• Wear from towing, hauling, or heavier wheel and tire setups
• Fluid leakage related to seal wear

Installation Notes

Fits 1999-2004 Toyota Tacoma, front. Verify compressed length, extended length, and mount style before installation: compressed length 9.37 in., extended length 14.13 in., stroke length 4.76 in. Lower mount type is E3(61.6X82X10) and upper mount type is S1. This shock is intended for Tacoma front suspension service where the original mounting configuration matches these specifications.

Quality Assurance

KYB designs the Gas-a-just line with monotube construction and application-specific valving for Toyota Tacoma trucks. Part number 553360 is built to deliver consistent damping response and support the vehicle systems that rely on suspension performance.
