ARP L19 Head Studs for the 1993-2002 Toyota Supra 2JZ Engine, also fits the 1JZ Engine.

While the price for these headstuds might seem high, they can actually present a better value than the 1/2" stud package.

In addition to having a higher clamp load rating than the 1/2" studs.  The L19 units can be more cost effective than having to purchase the 1/2" studs plus having your block machined plus having your head machined plus buying a custom headgasket.

That's not to mention the down time you save by not having to send all of your stuff out to the machine shop.

The L19 stock dimension (stock fitment) head studs have approximately 35% higher clamp load rating than the standard head studs for the 2JZ

And approximately 4% higher clamp load rating than even the mighty 1/2" head studs.

A Must for anyone going 800hp
