XAT ARP 2000 Head Stud Kit UZ Series V8 1UZ 2UZ 3UZ HSK

LISTING IS FOR HEAD STUDS FOR 1 COMPLETE ENGINE, BOTH HEADS! 

Head studs need to be torqued to 70 ft/lbs 

If you are building a bullet proof UZ series V8, you will need the ARP Stud kits found here. If you're building a HIGH HP UZ, you'll definitely need this ARP2000 version. XAT Racing leads the world in Toyota/Lexus V8 parts! One of the most important and integral upgrades when squeezing more power out of the UZ engines is to go with better fasteners. We've developed a custom kit (not just reused other kits) to give your V8 a bit more room to work with safely, especially if you plan on boosting it! 

What's important about these ARP studs? The factory bolts are torque to yield, meaning they are purposefully stretched after one use, and cannot be safely reused. These ARP studs can be used countless times in multiple engine builds, provided they are not stretched. Studs also give you a more solid clamping force over bolts. Check out the excerpt from ARP's catalog for an explanation we have in the pictures! 

The added tensile strength of the ARP2000 material lets you torque the studs down further, giving you even more protection from lifting the heads and/or blowing a head gasket, and is good for engines making 800+ HP

You should not have to shave the head studs down for the scissor gears for the cams. We include washers for non-VVTi applications to make installation easier.
