Customer Questions & Answers

  • Question: How many bolts are included in this kit?

    Answer: There are 12 bolts included in this kit.
  • Question: Can these bolts be reused?

    Answer: Yes, these bolts are removable and reusable.
  • Question: Does the double hex head include an allen head?

    Answer: Yes, the double hex head includes a 3/16 inch recessed allen head.
  • Question: Will the kit work on a small block 327?

    Answer: No, they are for LS1. You would need 8911 for the older small block.
  • Question: Will this kit work on 6.0?

    Answer: Yes, all LS motors have the same bolt needs for their exhaust.
  • Question: Will this fit a 93 Firebird 5.7 LT1?

    Answer: To be 100% sure, I recommend going to their web page and looking them up. However, if an LT-1 uses the same size as an LS-1/LS-6, then yes it will.
  • Question: Are they 8mmx25mm?

    Answer: Yes, per the description they are 8 millimeter 1.25 X 25 millimeter 6 point bolts with a double hex head.
  • Question: Will this fit on a 2000 Sierra 4.8?

    Answer: No, they did NOT fit my 1997 GMC Sierra. I had to re-install the stock bolts.
  • Question: Will these work on a 1999 2 Door Tahoe with the 5.7 Vortec?

    Answer: Be careful, I think the 99 Tahoe was still the LT style motors, which have SAE fasteners. All the LS series engines have metric, which is what these bolts are.
