KYB KG4738 Shock Absorber - Rear

KYB Gas-a-just Rear Shock for Toyota RAV4

The KYB Gas-a-just KG4738 is a rear suspension shock absorber built for Toyota RAV4 applications that need firmer control and quicker response than a standard twin-tube design. It uses a monotube layout with separate gas and oil chambers to reduce fade and maintain consistent damping during everyday driving and heavier-duty use.

Key Features

• Up to 25% more damping performance than original equipment shocks
• Monotube construction separates gas and oil for fade-free operation and fast response
• Higher gas pressure improves steering response and suspension control
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Valving and components are engineered specifically for the Toyota RAV4
• Designed for vehicles that work, tow, or use larger and heavier tires and wheels
• Dust cover included

Product Details

KYB Gas-a-just shocks are designed to deliver responsive damping by using an air-free hydraulic working area and a high-pressure nitrogen gas chamber with a floating piston. That design helps the KG4738 react quickly to road inputs while maintaining ride comfort during normal driving. For Toyota RAV4 owners looking for a rear shock absorber that supports added load, towing demands, or upgraded wheel and tire setups, this part number offers a direct-fit performance-oriented solution. This part cross-references Monroe Shocks & Struts (e.g., 37199) for the same application.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced control after shock fade from heat or aeration
• Loose steering feel caused by weak rear damping
• Ride instability with heavier tires and wheels
• Rear suspension wear symptoms on higher-mileage Toyota RAV4 models

Installation Notes

Fits 2001-2005 Toyota RAV4, rear. Fits 1996-2000 Toyota RAV4, rear. Verify compressed length, extended length, and mount types before installation: compressed length 14.76 in, extended length 24.17 in, stroke length 9.41 in, lower mount type E1, upper mount type S1. The dust cover is included, and the shock uses an R-stop configuration with no internal rebound spring and no B-stop.

Quality Assurance

KYB designs the Gas-a-just line as a monotube shock absorber with performance-focused valving and construction intended to maintain consistent damping response. The KG4738 is built to support the suspension behavior expected on Toyota RAV4 rear applications and to help keep vehicle systems operating as engineered.
