Excel-G Product Line Details

The KYB Excel-G line is engineered as an Original Equipment for the Aftermarket solution. It uses the same type of OE-quality components and calibration approach found on KYB original equipment production, with the goal of returning the vehicle to its designed ride characteristics rather than changing them.

Detailed Description

KYB 344263 is a rear shock absorber for a wide range of GM rear suspension applications, including 1988-1999 Chevrolet C1500 and K1500, 1995-1999 Chevrolet Tahoe, 1988-1999 GMC C1500 and K1500, and 1992-1997 GMC Yukon. It also covers additional Chevrolet and GMC heavy-duty and 3/4-ton and 1-ton rear applications listed in the fitment data. This part cross-references Monroe Shocks & Struts (e.g., 37044) for the same application.

With a compressed length of 15.71 inches, extended length of 26.73 inches, and stroke length of 11.02 inches, this shock is built to match the specified rear suspension geometry. Lower mount type E2(14.6X42) and upper mount type E3(61.6X87X0) should be verified against the original part before installation.

What It Helps Address

• Excessive rear bounce after bumps
• Loose or unstable rear-end feel during lane changes
• Reduced tire contact over uneven pavement
• Delayed body control during braking and cornering
• Oil or gas leakage from a worn rear shock absorber
