Review on 12PCS Turbocharger & Exhaust Manifolds Up-Pipe Bolts for 2001-2016 Duramax Diesel - EASYBERG by Timothy Schroeder

Revainrating 4 out of 5

Thread m10x1.5, length 30 mm, head 10 mm, 12 points.

It's not exactly OEM. If you were expecting a 12mm 12 point head then this product is not for you. At first I was frustrated because it is very difficult to find a 10mm 12 point socket in stock at a local store and it was not mentioned in the product description. However, after installation I noticed 2 advantages: 1) The thinner 10mm coupler makes it easier to install top tubes on the LB7, especially on the driver's side. 2) They are harder to twist. On my LB7 exhaust kit, I had to tighten them to 39 ft-lbs on all 12 top tube bolts. These screws also fit on the down tube.

Pros
  • M10 12 head bolts, grade 12.9 (tensile strength 160,000 psi).
Cons
  • I don't remember but there was something
