46MM 4 Bolt Aluminum Gasket - 1.81 Inches
Lightweight aluminum gasket with 4-bolt configuration designed for precision engine sealing. Built from solid aluminum construction, this gasket delivers reliable compression and durability in high-heat applications. The 1.81-inch bore size fits specific engine blocks and carburetor manifolds where exact dimensions matter.
Do I need to surface the mating surfaces before installing this gasket?
Yes. Clean both engine block and component surfaces with a gasket scraper to remove old material and debris. A light pass with fine sandpaper ensures better compression and seal integrity. Do not use excessive force that could damage the aluminum.
What fasteners do I need to secure this gasket?
The gasket requires 4 bolts sized to match your engine's factory bolt holes. Fastener type and length depend on your specific application — check your service manual for torque specs and bolt diameter to avoid leaks.
Can I reuse this gasket if I remove it for inspection?
Aluminum gaskets compress permanently during installation. Once installed and torqued, treat it as a single-use item. Reinstalling a compressed gasket risks poor sealing and exhaust or coolant leaks.
