KYB Gas-a-Just Rear Shock for Montero

The KYB Gas-a-Just KG54303 is a rear suspension shock absorber built as an OE monotube replacement for the Mitsubishi Montero. It is engineered for responsive control, stable ride quality, and consistent damping in daily driving and heavier-duty use.

Gas-a-Just Line Details

KYB Gas-a-Just monotube shocks use separate hydraulic and high-pressure gas chambers to keep oil and gas isolated for quick response and fade-resistant operation. This design adds damping performance over original equipment and is suited for vehicles that work, tow, or run larger tires and wheels.

Key Features

  • Part number KG54303
  • Rear suspension shock absorber for Mitsubishi Montero applications
  • Monotube design with air-free hydraulic control area and high-pressure nitrogen gas chamber
  • Up to 25% more damping performance over original equipment shocks
  • Triple chrome plated piston rod helps reduce seal wear and fluid leakage
  • Improved steering response from higher gas pressure
  • Dust cover included
  • Lower mount type: E2(16X38); upper mount type: S1
  • Compressed length: 11.57 in; extended length: 17.99 in; stroke length: 6.42 in

Fitment

  • Fits 1997-2000 Mitsubishi Montero, rear; Recommended OEM Replacement; (Exc. Adjustable Suspension); Gas-a-just
  • Fits 1992-1996 Mitsubishi Montero, rear; Recommended OEM Replacement; (Except Adjustable Suspension); Gas-a-just
  • Fits 1992-1996 Mitsubishi Montero, rear; Recommended OEM Replacement; (For Adapting VSA to Non-VSA Suspension); To Convert from Electronic Susp. - See Paper Catalog Appendix C; Gas-a-just

What It Helps Address

  • Excessive rear bounce or oscillation
  • Reduced damping control from worn OE shocks
  • Fluid leakage caused by seal wear
  • Soft or inconsistent rear suspension response under load
  • Delayed steering and chassis response on Montero models

Installation Notes

Verify rear fitment by year, suspension configuration, and mount style before installation. This part cross-references Monroe Shocks & Struts (e.g., 32274) for the same application. For 1992-1996 Mitsubishi Montero and 1997-2000 Mitsubishi Montero rear applications, confirm whether the vehicle has adjustable suspension or electronic suspension conversion requirements before ordering.

Quality Assurance

KYB designs the Gas-a-Just line as an OE-style monotube replacement with application-specific valving for the Mitsubishi Montero. The KG54303 is built to restore original suspension control while maintaining fade-resistant performance in demanding rear suspension use.
