Skip the expensive labor of a machine shop and get our 1/2" head studs fitted yourself! This kit is reusable so that you can use it on multiply engines. This kit is made specifically for Gen III and Gen IV LS engines.

The 1/2" head bolts allow for more clamping pressure, better head gasket seal, and gives the user the ability to make more power safely.

The kit includes everything you need to do the job yourself. If you need to work on the lower 4 bolt holes on 6 bolt blocks (for upgrading to 3/8-16), you can add that option from the drop-down menu as well, which will add the following:

• Drill bushing for tap drill
• Guide bushing for tap
• Coated HSS Drill for tap hole
• Precision 3/8-16 Tap
  

Cylinder Head:

After performing the job on the block, you can use the DIY Head Fixture on the heads to make room for the larger studs. Bolt the fixture to your head and use the larger, 33/64in drill bit (included in the kit). This will provide ample room for the new, larger 1/2in studs.

Important:

Tick Performance DIY Head-Stud Upgrade Fixture is designed to work with the Tick Performance ARP 1/2in head stud kit ONLY (GEN III or GEN IV). The fixture and instructions may not work with another brand 1/2in head-stud kit.

• Drill bushing for counterbore
