What it does

Torque-to-yield head bolts are one-time-use; reusing them is the fastest way to a fresh head gasket failure. A new bolt kit, or a stud kit for boosted and high-cylinder-pressure builds, gives the gasket the even, repeatable clamp load it is designed for.

• Chevrolet vehicles with the Duramax LLY / LBZ engine, 2004-2007
• GMC vehicles with the Duramax LLY / LBZ engine, 2004-2007

Fixes

• a head gasket replacement (TTY bolts are single-use)
