KYB 344266 Shock Absorber - Front

KYB Excel-G Front Shock Absorber

KYB Excel-G 344266 is a front suspension shock absorber built to restore original ride control, stability, and steering response. It is a direct OE-style replacement for a wide range of Chevrolet, GMC, and Cadillac trucks and SUVs, including front applications for the Chevrolet Astro, GMC Safari, Chevrolet Tahoe, and GMC Yukon.

The Excel-G line is KYB’s OEA-style replacement program, built on the same assembly lines and with the same OE-quality components used in original equipment production. Part number 344266 is a nitrogen gas-charged, twin-tube shock designed to return the vehicle to its intended damping characteristics without changing the factory ride balance.
