Excel-G Product Line

The KYB Excel-G line is calibrated to return the vehicle to its original damping behavior rather than change ride feel. For owners searching for a KYB 344045 rear shock absorber for a Nissan Pathfinder, Mitsubishi Montero, or Toyota Pickup, Excel-G is built as an OE-style replacement focused on factory-like control.

Detailed Description

KYB 344045 is an OEA-classified replacement shock absorber for rear suspension applications. It uses KYB’s OE manufacturing standards, including in-house damping valve calibration and quality sealing components, to help maintain consistent tire contact and body control. The design is intended for vehicles where restoring factory ride behavior matters, including 1987-1995 Nissan Pathfinder rear, 1983-1989 Mitsubishi Montero rear, and 1979-1983 Toyota Pickup rear applications.

Additional confirmed fitments include 1997-1999 Mitsubishi Montero Sport rear, 1983-1994 Mitsubishi Mighty Max rear, 1987-1993 Dodge Ram 50 rear, 1987-1989 Dodge Raider rear, 1983-1986 Dodge Power Ram 50 rear, 1982-1986 Nissan 720 rear, 1980-1982 Chevrolet LUV rear, 1982 Dodge D50 rear, and 1958-1960 Pontiac Bonneville rear.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unsettled handling in turns and lane changes
• Reduced tire contact from worn damping
• Oil or gas seepage from aging shock seals
• Inconsistent ride control on trucks and older rear suspension setups

Installation Notes and Tips
