ARP HEAD STUDS SUIT NISSAN NAVARA PATROL ZD30 DDT DDTI

Description

This ARP head stud kit has been specially designed and manufactured for Nissan ZD30 DDT and DDTi 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 these head studs deliver a clamping load of 19000 lbs.  This is an increase of 17% clamping load over OE head bolts.

At 85% of yield strength these head studs deliver a clamping load of 21500 lbs.  This is an increase of 32% clamping load over OE head bolts.

Set includes ARP Ultra-Torque lubricant.
