MAHLE_GM Vortec Head Set

New from MAHLE – the head gasket set for 1996-2002 General Motors 5.7-liter Vortec engines. This gasket set features advanced technology for a superior seal and reliability. See more details below.

Official Release:

The MAHLE Original head gasket set for 1996 – 2002 General Motors 5.7-liter, 8-cylinder “Vin:R,“ Vortec engines features OE quality construction. The exhaust manifold gaskets are made from multi-layer steel (MLS) and the intake manifold gaskets have new technology polymer construction for superior sealing. The set includes all the parts – 35 pieces in total – that technicians need to do the job.

The intake manifold gaskets in the GM Vortec head set (part no. HS5746C) use new technology: a hydrogenated nitrile butyl rubber (HNBR) constrained sealing bead on a molded polymer carrier. The coolant ports are fully encapsulated with HNB to protect against organic acid technology (OAT) coolant. Metal load limiters are incorporated to prevent over-torquing. They protect the carrier against thermal expansion and contraction.

The exhaust gasket in the GM Vortec head set utilizes 301 full hard stainless steel featuring an embossment on each layer at critical sealing areas to enhance sealing. The spring steel layers provide tension when compressed, keeping the joint tight and preventing the seal from being blown out. The MLS construction used in MAHLE Original gaskets is superior to composite gasket materials that do not match the OE design.

“You can see the difference with MAHLE Original gasket sets,” said Jon Douglas, general manager of MAHLE Aftermarket North America. “MAHLE Original gaskets match the OE gaskets for form, fit and function. Plus, we include everything the technician needs to get the job done right.”
