Stripped threads in a cylinder head can bring an engine build to a screeching halt. Save your investment with the BTR Rocker Bolt Hole Repair Insert. Specifically engineered by Brian Tooley Racing, this heavy-duty insert provides a reliable, permanent fix for damaged rocker arm bolt threads. Instead of replacing an entire cylinder head, this insert reinforces the compromised area and restores factory-spec structural integrity.

Flawless Thread Restoration: Seamlessly adapts a damaged factory M8-1.25 thread size out to a robust M12-1.75 outer diameter.
Sold Individually: Purchase exactly what you need for a single-hole patch or stock up to have spares on hand for your shop.
