GPI OEM Style Complete Head Bolt Kit for 2004+ LS Engines - GBK-LS04
Complete OEM-Style Cylinder Head Bolt Kit for LS Engines
The GPI GBK-LS04 OEM Style Head Bolt Kit is engineered for 2004 - 2014 Chevrolet LS engines, offering a complete set of high-quality, factory-style fasteners for reliable cylinder head installation. Built from durable chromoly steel with a cadmium-plated finish, these bolts are designed to meet OEM torque-to-yield requirements while delivering dependable clamping force for both stock and performance builds.
Each kit includes the exact fasteners needed to service one cylinder head. Because LS engines use torque-to-yield (TTY) hardware, these bolts are designed for single-use installation and must be replaced whenever the cylinder head is removed.
Product Overview
These OEM-style head bolts replicate GM's second-design 2004 - 2014 LS fastener layout, which uses two different bolt lengths: ten 100mm bolts and five 45mm bolts per cylinder head. They provide accurate loading, consistent torque retention, and proper alignment of the cylinder head during installation. Perfect for LS rebuilds, top-end refreshes, or cam upgrades requiring head removal.

FAQs
How many kits do I need for a complete LS engine?
You will need two kits, as each set services one cylinder head. LS engines use separate fasteners for each side.
Are these bolts reusable?
No. These are torque-to-yield bolts and are good for one use only. They must be replaced anytime the cylinder heads are removed.
