AUTOBABA Cylinder Head Gasket Kit with ES72173 Bolts – Fits 2002-2011 GM 4.8L/5.3L V8 Engines

Overview

Designed by AUTOBABA for GM’s 4.8L and 5.3L V8 powerplants, this cylinder head gasket kit combines high‑quality MLS gaskets with a complete hardware set to support a full head gasket service.

The result is a comprehensive kit that supports a thorough engine refresh without guesswork.
