Victor Reinz Exhaust Manifold Gasket Set 11-10634-01

Victor Reinz 11-10634-01 is an exhaust manifold gasket set built for high-heat sealing at the manifold-to-cylinder-head interface. It uses a fiber-and-metal construction with a 0.040-inch thickness and a two-piece configuration to support a precise seal on square port exhaust manifolds.

Fits a wide range of Chevrolet, GMC, Buick, Cadillac, Oldsmobile, and Pontiac applications, including classic and late-model trucks, vans, and performance cars such as Chevrolet Camaro, Chevrolet C1500, and GMC K2500. This part cross-references MAHLE MS7110X for the same application.

Key Features

Part number: 11-10634-01
Exhaust manifold gasket set for square port exhaust manifolds
Fiber and metal sealing material for heat-resistant exhaust sealing
0.040-inch thickness for consistent manifold sealing
Two-piece configuration
OE-specification heritage from Victor Reinz exhaust sealing systems

Detailed Description

Victor Reinz has a long history of supplying exhaust manifold gaskets to original equipment vehicle manufacturers, and this gasket set reflects that OE-focused engineering approach. The 11-10634-01 is built for vehicles that use square port exhaust manifolds, covering applications across decades of GM passenger cars, trucks, vans, and SUVs. If you are servicing a Chevrolet Camaro, Chevrolet Impala, GMC Jimmy, or similar square-port application, this gasket set provides the sealing profile needed for exhaust manifold service.

The fiber-and-metal design helps maintain sealing integrity under the extreme temperatures common at the exhaust manifold. The two-piece layout and 0.040-inch thickness support proper fitment on the listed applications, including Chevrolet C10, Chevrolet K20, GMC G3500, and Pontiac Firebird models.

What It Helps Solve

Exhaust leaks at the manifold-to-head sealing surface
Noise from a leaking exhaust manifold joint
Loss of sealing after manifold removal or service
Heat-related gasket breakdown on square port exhaust systems
Fitment issues on listed Chevrolet and GMC square port applications

Installation Notes and Tips

Verify that the cylinder head and exhaust manifold sealing surfaces are clean, flat, and free of old gasket material before installation. Confirm square port exhaust manifold fitment before ordering, since this part is application-specific. Follow the vehicle service manual for torque sequence and tightening specifications to help achieve an even seal.

Quality Assurance

Victor Reinz supplies exhaust manifold sealing products with OE-specification coverage across a broad range of vehicles, from classic muscle-era applications to later GM truck and van platforms. Part number 11-10634-01 is engineered for the listed square port exhaust manifold applications and built to meet the sealing demands of high-temperature exhaust service.

This part fits 1790 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
