KYB Excel-G Rear Shock Absorber

The KYB Excel-G 343388 is a rear suspension shock absorber for select Nissan Pathfinder and INFINITI QX4 models. It is built to restore original ride control, steering response, and body stability while maintaining OE-style handling characteristics.

Key Features

  • OE-style replacement for Asian SUVs and crossovers
  • Nitrogen gas-charged, twin-tube shock design
  • Triple-lip fluid seal helps reduce oil and gas leakage
  • Vehicle-specific, hand-assembled damping valves manage tire contact and body motion
  • Strong strut body and bracket construction helps maintain alignment under load
  • Dust cover included
  • R-stop design included

Product Line Details

KYB Excel-G is the brand’s OE replacement line focused on restoring factory-designed suspension performance rather than changing ride feel. The 343388 shock is manufactured on KYB OE assembly lines using OE-quality components and calibrated for original control on rear suspension applications.

Fitment

  • Fits 1999 INFINITI QX4, rear; recommended OEM replacement; excludes electronic adjustable suspension; to 11/98.
  • Fits 1999 Nissan Pathfinder, rear; recommended OEM replacement; excludes electronic adjustable suspension; to 11/98.
  • Fits 1997-1998 INFINITI QX4, rear; recommended OEM replacement; excludes electronic adjustable suspension.
  • Fits 1996-1998 Nissan Pathfinder, rear; recommended OEM replacement; excludes electronic adjustable suspension.

What It Helps Address

  • Excessive bouncing after bumps
  • Reduced rear-end stability during lane changes
  • Loose or delayed steering response from worn rear damping
  • Uneven tire contact caused by weak shock control
  • Suspension noise or fluid leakage from aged shock absorbers

Installation Notes

Verify rear suspension configuration before ordering, especially on vehicles with electronic adjustable suspension, which is excluded from this application. Confirm compressed length, extended length, and mount types against the original part before installation. This part cross-references Monroe Shocks & Struts (e.g., 37158) for the same application.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and Excel-G is produced on the same OE assembly lines using OE-quality components. The design is calibrated to restore factory performance for the listed Nissan Pathfinder and INFINITI QX4 rear applications.
