Manifold studs secure your exhaust manifold or headers to the cylinder head, and are a common failure point on high-mileage or high-heat applications, particularly where studs have corroded or been over-torqued in the past. We stock replacement studs in a range of thread sizes, alongside manifolds and manifold gaskets.

Why do exhaust manifold studs break?

Manifold studs are exposed to extreme heat cycling and can corrode or become brittle over time, making them prone to snapping, especially if they've been over-torqued or previously damaged during a manifold removal.

What sizes do manifold studs come in?

Manifold studs are available in a range of thread sizes and lengths to match different engine applications – check your engine's specifications or contact our team to confirm the correct fitment.

Do I need a new gasket when replacing manifold studs?

Yes, it's best practice to fit a new manifold gasket whenever the manifold has been removed, since the old gasket rarely seals reliably once disturbed.

Are stainless steel manifold studs better than standard steel?

Stainless steel studs generally resist heat-related corrosion better than standard steel, reducing the risk of studs seizing or snapping during future maintenance.
