These bolts are designed to be used in place of the OEM bolts utilized on the TBSS, NNBS, and L92 Gen IV intake manifolds (GM part number 12575384).

The listing is for a full set of 10 bolts and washers. Grade 10.9 and made in the USA! Intake manifold fitment includes: 06-09 Trailblazer SS 07-13 GM Truck 4.8L, 5.3L, 6.0L 07-13 L92 6.2L
