Great replacement
Did a rear main seal job on my stock 05 Tahoe with a 5.3 and decided to replace the flywheel bolts. These worked perfectly. Make sure to torque and use loctite.

Awesome quality, as always with ICT.
High quality product for my engine build. Anything from ICT is a great solution. They fit as expected and look like they are higher quality than the OEM boots. They function as you would expect. My flywheel is still attached.

These may seem short compared to OEM bolts. However with Red Loctite and proper Torque spec these hold just fine.
