L19 Extreme Duty Head Studs have arrived!
After a long wait, our production run of ARP L19 head studs have arrived. As you will recall, since the standard ARP studs can only be trqed down to 65ft/lbs, people are having issues with head lift.
These L19 head studs are a direct drop in replacement for factory head bolts, or the standard ARP studs. No block modifications or extra labor are required. These studs can be torqued down to 90-95ft/lbs, for a 40%+ increase in clamping force. Kits include studs, washers and nuts, are have an allen key hole for easy installation and removal.
If you pre-ordered, your item will be shipping immediately.

We have been using these studs for awhile on Supra 2JZ motors.they work really well andI think Sharif is being a little conservative when he says 95 ft/lbs:^)We have torqued them way beyond that.

Here is the link: http://www.forgedinternals.com/store...7&cat=0&page=1 $490 shipped for the set.
Tim is right. L19 studs, depending on their diameter, can usually be trqed to between 100-170ft/lbs without distorting. It is a very strong material. However, with the factory aluminum block, I think 90-95ft/lbs is a good conservative estimate. My partner in crime tested the thread strength of the block to 110 ft/lbs before the threads in the block let go. Therefore, we are suggesting 90-95ft/lbs.

As long as the car is properly tuned, and cooled. These upgraded studs are great, but detonation will knock out any stud/HG package pretty quickly and very violently.

Can the heads be taken off with out pulling the motor ? Or is it just easier to do it that way . My shop mentioned pulling the motor because it would be easier to access the front of the motor .
good question..Also can you refund the other studs if we send it back for the new ones?

You can buy 1/2 ARP standard steel studs for $250, but you'll spend a few hundred more on install. These studs are most appropriate for those trying to maximize power on an unsleeved block, as Todd mentioned.
One last note, engines built by BuiltZMotors, and Import Parts Pro will be offering these studs as a customer option.
