Product Videos
In this video we're going to touch base on an option you have if you're rebuilding your engine or doing head gaskets on a 4.0 / 4.6 Land Rover Engine.
And that is, essentially, a replacement set of studs instead of head bolts.
Now you know a lot of the newer engines have the torque to yield head bolts, which you see a lot now on aluminum head engines.
You're dealing with a high expansion and contraction rate which is why you need that style.
But you find it if you look if you see a racing engine torn down a lot of them will have studs.
The studs are a little bit more secure.
They cost a little bit more but they definitely do a better job.
Watch Doug, our Land Rover Master Technician, install ARP Engine Head Bolts using Kit ARP4301 on a Land Rover 4.0/4.6 Engine.
Doug also includes discussion of how to properly torque in the studs.
