The Tick Performance solid dowel pins for LS engines are a superior option to factory-style split dowel pins. With a larger ID, these are required when upgrading to 1/2in head studs. The solid design provides more security and accuracy to your build.

See the Tick Performance DIY 1/2in Head-Stud Fixture.

These will work on all factory-style LS blocks.

One pack (4) will supply enough for an entire LS engine.
