JEGS Head Bolt Kits

JEGS Premium head bolts are available with a reduced hex size (1/2" compared to stock 5/8") with a wide area head flange that eliminates valve train removal to aid in re-torquing of the cylinder heads. All High Performance Series bolts are 170,000 psi chromemoly alloy steel, which is approximately 15% stronger than Grade 8. Each bolt is then finished with the distinctive JEGS J-Crown. Kits come complete with hardened double disc ground and chamfered 4130 heat-treated steel washers (also available separately). Head bolts and washers are coated with black oxide for durability. Bolts sold in complete engine sets. Made in the USA.
