KYB KG5494 Shock Absorber - Rear

KYB Gas-a-Just Rear Shock for Toyota Previa

The KYB Gas-a-Just KG5494 is a rear monotube shock absorber engineered for 1991-1997 Toyota Previa models. It adds firmer damping response than a conventional twin-tube design, making it a direct choice for drivers who want improved control on a Toyota Previa rear suspension.

Key Features

• Fits 1991-1997 Toyota Previa, rear
• Monotube design separates gas and oil for consistent response and fade-resistant operation
• Up to 25% more damping performance than original equipment shocks
• High-pressure nitrogen gas helps the shock react quickly to steering and road inputs
• Triple chrome plated piston rod helps reduce seal wear and fluid leakage
• Designed specifically for the Toyota Previa application
• Dust cover included

Gas-a-Just Product Line

KYB Gas-a-Just shocks are built for vehicles that carry heavier loads, tow, or run larger wheels and tires. The KG5494 uses a high-pressure monotube layout with separate working chambers, giving the rear suspension of the Toyota Previa quicker response and more controlled damping during normal driving and under added demand.

This part cross-references Monroe Shocks & Struts (e.g., 37074) for the same application.

Detailed Description

The KYB KG5494 rear shock absorber is a performance-oriented replacement for the Toyota Previa. Its monotube construction keeps the hydraulic and gas chambers separated, which supports stable damping and helps prevent fade from aeration. With a compressed length of 11.81 inches, extended length of 19.09 inches, and 7.28 inches of stroke, this shock is built to match the rear suspension geometry of the listed Previa applications. The upper mount type is E1 and the lower mount type is S1.

For Toyota Previa owners looking for a rear shock that responds quickly and maintains control, the KYB Gas-a-Just KG5494 delivers a firmer, more immediate feel than OE-style twin-tube designs. It is a practical upgrade for a Toyota Previa rear shock replacement when the goal is improved damping consistency and steering response.

What This Shock Helps Address

• Excessive rear bounce after bumps or dips
• Reduced control from worn or leaking rear shocks
• Soft or delayed damping response in the rear suspension
• Instability when carrying cargo or driving with heavier wheels and tires
• Loss of ride consistency caused by shock fade

Installation Notes and Tips

Verify rear fitment before installation on 1991-1997 Toyota Previa models. Match the upper mount type E1 and lower mount type S1 to the vehicle’s original mounting points, and compare compressed and extended lengths to the removed shock before final installation. Inspect surrounding suspension components, bushings, and mounts for wear while replacing the shock absorber.

Quality Assurance

KYB is a well-known OE supplier in the suspension market, and the Gas-a-Just line is built with application-specific valving and durable construction for consistent performance. The KG5494 is designed for direct rear fitment on the Toyota Previa and uses a triple chrome plated piston rod to help reduce seal wear over time.
