有疑問？ 和我們聊天

客戶問答

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

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

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

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

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

    Answer: Yes, all LS motors have the same bolt needs for their exhaust.
  • 問題: 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.
  • 問題: 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.
  • 問題: 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.
  • 問題: 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.

Stage 8 Header Bolts Editorial Review

The Stage 8 8900 Locking Header Bolt Kit is perfect for LS engines as it contains 8 millimeter 1.25 X 25 millimeter 6 point bolts with a double hex head, and 12 each locking retainers and clips. It ensures that there won't be any need to fool around with bolts as they are secured well. However, it's important to check if the product would fit as there have been cases where the kit wouldn't fit certain models.
