Product Description

Nissan 2.5L RB25 Inline Head stud Kit 202-4309

Cylinder ARP head stud kit for Nissan with 2.5 RB25 inline engines.

Kit comes with studs, washers, and nuts needed for a direct bolt on, as well as the ARP moly-lube and instruction sheet.

ARP studs are made from premium 8740 alloy, rated far superior to aircraft quality materials. Each set is heat treated to 200,000 psi, thread Rolled after heat treating, which results in a stud 1000% better than studs that are thread rolled prior to being heat treated. The kit includes 12-point nuts and hardened parallel ground washers. Using studs will make it much easier to assemble an engine. Studs provide more accurate and consistent torque loading. When you use bolts, the fastener is actually being twisted as torque is being applied to the it. The bolt is thus reacting to two different forces simultaneously.

Replace your stock head bolts with ARP heavy duty head studs. The stud design helps the head and the block equalize the pressure better thereby creating a much more even and consistent seal. It is recommended to replace the head studs/bolts with a new set if the head bolts are ever loosened due to metal fatigue. Reusing an old and possibly warped or stretched head bolts/studs will sacrifice the seal between the head and block and may cause head gasket leak. This is a great an easy upgrade when doing an engine rebuild or building a race motor.
