FITS ALL GM LS BASED EXHAUST MANIFOLDS

GM 11518860 is a genuine General Motors exhaust manifold bolt. It is primarily used to secure exhaust manifold heat shields or as mounting hardware directly to the cylinder head on V8 engines (such as the 4.8L, 5.3L, and 6.0L).

Because original manifold bolts are highly prone to snapping, this part number is heavily referenced in aftermarket repair clamps (like Dorman 917-142) designed to fix exhaust leaks without having to extract broken studs.
