Detailed Product Overview

KYB Excel-G 346602 is engineered as a suspension shock absorber that returns the vehicle to its intended ride characteristics. The twin-tube, nitrogen gas-charged design uses OE-quality components and calibrated damping to control rebound and compression without changing the factory feel. This makes it a practical choice for drivers and technicians looking to restore suspension performance on Chevrolet trucks and other listed applications.

This part cross-references Monroe Shocks & Struts 65169 for the same application. Part number 346602 is also associated with Chevrolet OE references 15174901, 15174903, 88982685, and 88982687.
