KYB 3410120 Suspension Shock Absorber - Rear

KYB Excel-G Rear Shock Absorber

The KYB Excel-G rear shock absorber is built to restore original ride control, stability, stopping performance, lane-change response, and handling. This nitrogen gas-charged, twin-tube shock is calibrated to return the vehicle to its OE-designed behavior rather than change the suspension feel.

Part number 3410120 is made on KYB OE assembly lines using OE-quality components. It is an OEA (Original Equipment for the Aftermarket) replacement for drivers and technicians who want factory-style performance on applications such as the Buick Enclave, Cadillac XT5, Cadillac XT6, Chevrolet Blazer, Chevrolet Traverse, Chevrolet Traverse Limited, and GMC Acadia.

Installation Notes and Tips

Verify rear fitment by year, model, and suspension configuration before installation. This shock is not for vehicles with electronic controlled suspension where excluded in the fitment notes. Confirm the lower E2 (12x58) and upper S1 (10MM) mount types, along with compressed and extended length, against the original part before service. Dust cover is not included.

That OE-focused manufacturing approach supports consistent replacement performance for the listed applications. Part number 3410120 is an OEA replacement built to restore original suspension behavior.
