Cylinder Head Stud Set – ARP
ARP2000 Performance cylinder head stud set to suit R425 2.5L DURAMAX (LVN), R428 2.8L DURAMAX (LWH) & R428 2.8L DURAMAX II (LWN) engines in Holden Colorado 06/2012 onwards. There are ten studs with washers and nuts to suit. No modification to head bolt holes in the block or head is required. 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. Set includes ARP Ultra-Torque lubricant. (ARP brand - made in USA)
