Product Description
P1 Point One LS Head Bolt Kit K003-H04E
Fits 1997-2003 LS Based Gen 3 Engines 4.8L 5.3L 5.7L 6.0L
High Strength E190 Material Head Bolt Kit
This kit is for 1997-2003 (and some early 2004) LS engine blocks which use 8 longer 11mm diameter bolts per head and 2 shorter 11mm bolts. If your block takes 10 bolts that are all the same length, see our 2004-later bolt kits.
Point One's E190 series Head Bolts boast an impressive 190,000psi nominal tensile strength to keep the cylinder heads firmly sealed on your high powered LS build. All fasteners are individually racked and heat treated in-house in vacuum furnaces under the supervision of a full-time metallurgist, and made from only USA sourced high quality steel. Every bolt is straightened and centerless ground for exceptional concentricity, and the threads are then rolled post-heat treatment to provide optimal strength. Washers are hardened and double-disc ground, further contributing to consistent torque results.
Every critical fastener is made start to finish in Point One's state-of-the-art facility in Rogersville, Missouri. Fasteners are packaged in vacuum sealed bags with external threads sleeve-protected and surrounded by dense foam to ensure your P1 studs arrive in pristine condition. Choose Point One for uncompromising strength, precision engineering, and the quality of American craftsmanship.
