New from Earl’s – their line of popular Cylinder Head Bolts. These bolts are 15% stronger than Grade 8 bolts and made from 170,000-PSI chromoly steel. See more details below.

Official Release:

Earl’s Cylinder Head Bolts are about 15 percent stronger than the strongest Grade 8 bolts and available for a huge array of popular applications. Manufactured from 170,000-PSI chromoly steel, they feature a reduced wrench size (12-point or hex-head) for extra socket clearance around the rocker arms when you re-torque the heads. The wide-flange head distributes the load evenly and provides additional support for the extra-thick chromoly washers. Available in a black-oxide finish and sold in complete sets, these made-in-the-USA fasteners are reusable, eliminating the hassle and expense of replacing OEM-style torque-to-yield bolts each time you remove the heads.

  • 15 percent stronger than the strongest Grade 8 bolts
