ARP2000 Isuzu 4JX1TC & 4JJ1 HEAD STUD SET

This ARP head stud kit has been specially designed and manufactured for c engines. There are eighteen (18) studs with 18 washers and nuts to suit. These studs will help gain the increased head clamping required in performance applications. They will achieve a more evenly distributed and accurate torque load compared to that of head bolts by eliminating the twisting force created during tightening.  This ultimately translates into higher reliability and a lower chance of head gasket failure.  At 75% of the fasteners yield strength this head stud kit delivers a clamping load of 15060 lbs. This is an increase of 15% clamping load over OE head bolts.  Set includes ARP Ultra-Torque lubricant. (ARP brand – made in USA)

Note: Thread in block needs to be tapped further to allow for studs longer thread
