What is included in this head bolt set?

This MAHLE Original head bolt set includes the necessary head bolts for the 6.6L Duramax engine. It does not include head gaskets, which must be purchased separately.

Why should I replace head bolts when removing cylinder heads?

Head bolts can stretch or weaken during engine operation. Replacing them with new bolts ensures they can achieve the correct torque specification, which is critical for maintaining a proper seal between the cylinder head and the engine block.

Are these bolts reusable if I only removed the heads for a short time?

It is always recommended to use new head bolts when reinstalling cylinder heads. Torque-to-yield bolts, common in many modern engines, are designed for a single installation and must be replaced to ensure proper clamping force and engine integrity.

Product Details

When you're rebuilding the top end of your 2017-2022 Chevrolet Silverado 2500 HD or 3500 HD, or your 2017-2022 GMC Sierra 2500 HD or 3500 HD, with the 6.6L Duramax engine, you need reliable parts. This MAHLE Original head bolt set gives you the critical fasteners needed to properly secure your cylinder heads. It's important to replace head bolts when removing cylinder heads, as they can stretch or weaken over time, compromising the seal. This set is designed to meet the torque specifications required for a solid seal.

MAHLE Original is a well-known name in engine components, and this head bolt set is built to perform. The bolts are made from strong materials to handle the clamping forces and heat cycles inherent in a diesel engine. Using new, properly torqued head bolts is a key step in ensuring your engine rebuild is done right, preventing leaks and maintaining compression. This set specifically excludes head gaskets, so you'll need to source those separately to complete your cylinder head installation.
