KYB 344072 Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber 344072

KYB Excel-G 344072 is a rear suspension shock absorber built to restore original ride control, stability, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components for a direct replacement approach on compatible Chevrolet and GMC trucks and SUVs.

The Excel-G line is KYB’s OEA-style replacement series, focused on returning the vehicle to its designed damping characteristics rather than changing ride feel. For full-size GM truck and SUV applications, that means consistent body control, steering response, and tire contact on the road.

Product Details

KYB 344072 is engineered for rear suspension service on classic Chevrolet Blazer, GMC Jimmy, Chevrolet C/K and GMC C/K trucks, and related Suburban and Blazer platforms. If you are replacing worn rear shocks on a Chevrolet K5 Blazer, GMC Jimmy, or a Chevrolet C10 Suburban, this Excel-G shock is built to match the original damping intent of the vehicle. This part cross-references Monroe Shocks & Struts (e.g., 37041) for the same application.

As part of the KYB Excel-G line, 344072 uses OE-style construction and calibration to help maintain predictable ride quality under load, during lane changes, and over uneven pavement. The part number 344072 is commonly searched for rear shock replacement on Chevrolet and GMC rear suspension applications where original control is the goal.
