Product Details
Worn-out head bolts can cause cylinder head gasket leaks. This ARP 157-4301 head stud kit is a direct fix for your Rover 3.9L-4.6L V8 engine with 10-bolt heads. ARP studs offer a more consistent clamping force than stock bolts, helping to prevent blown head gaskets under higher stress.
This kit uses 8740 chromoly steel, a strong material that holds up well to the heat and pressure in your engine. The studs are black oxide finished to resist corrosion. They feature a unique parallel ground, thread-rolled stud for maximum strength and fatigue life. The threads are rolled after heat-treat, which makes them much stronger than threads that are cut.
