Overview

The Mahle HS4021 engine cylinder head gasket set is built for GM truck and SUV applications that require OEM-standard sealing performance. It uses a solid core composite cylinder head gasket, a steel exhaust manifold gasket, and a molded rubber intake manifold gasket to support a complete top-end reseal.

Compatible With Chevrolet Tahoe, C2500, K1500, K2500, C1500, G20, and Blazer applications, plus GMC C2500, C3500, K1500, K2500, Yukon, C1500, and G2500 models in the listed years. The HS4021 is a fitment-specific solution for engines without the high output package.

Key Features

  • OEM standard grade for factory-style sealing performance.
  • Solid core composite cylinder head gasket construction.
  • Steel exhaust manifold gasket for durable sealing at the exhaust interface.
  • Molded rubber intake manifold gasket for intake-side sealing.
  • Includes miscellaneous gaskets and seals for related sealing points.
  • Torque-to-yield application support where specified by the engine design.

Detailed Description

Mahle HS4021 is an engine cylinder head gasket set for GM V8 applications that need a precise sealing package during head service or top-end repair. The set is built around materials selected for their specific sealing roles: composite for the head gasket, steel for the exhaust manifold gasket, and molded rubber for the intake manifold gasket. Mahle is known for supplying sealing products used by OEMs and technicians worldwide, and this part follows that OE-standard approach. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Use the HS4021 when servicing Chevrolet Tahoe or GMC Yukon engines, or when replacing the gasket set on Chevrolet C1500 and GMC K2500 trucks within the listed fitment. The part number HS4021 is also useful when searching for a Mahle cylinder head gasket set for 1994-1999 GM truck and SUV applications.

What It Helps Fix

  • Coolant or compression leakage at the cylinder head sealing surface.
  • Intake manifold sealing issues that can affect engine operation.
  • Exhaust manifold gasket leakage at the cylinder head interface.
  • Top-end reseal needs during cylinder head service.
  • Sealing wear on older GM truck and SUV engines.

Installation Notes

Confirm engine configuration before ordering, since fitment excludes high output engines. Cylinder head bolts are not included, and torque-to-yield fasteners should be replaced when required by the engine procedure. Positive type valve stem seals and the exhaust pipe gasket are not included, so verify related components before assembly.

Quality Assurance

Mahle gaskets are sealing products trusted by OEMs and technicians around the world. HS4021 is an OEM-standard gasket set built for application-specific sealing performance in GM engine service.
