ARP Head Studs Full Set - EVO X

Product Description

The factory head bolts can begin to stretch with higher cylinder pressures and cause a enough space between the block and head for combustion to leak out. Not only are you losing power, you are putting your cooling system and head gasket at risk.

Replacing the stock head bolts with ARP head studs creates a super-strong connection between the head and the block and will ensure a positive seal of the head gasket.

Using ARP studs not only makes a much more solid connection, they facilitate easier R&R of the head and can be torqued more accurately. Since no torsional torque is required turn the entire shaft (as with bolts), there is an extremely reduced risk of variation in torque from one stud to the next, which is much better for the aluminum head.

Includes: a set of 10 ARP2000 head studs, ten parallel ground washers, ten 8740 chrome moly steel 12pt nuts and a 1/2oz of. pack of ARP ultra-torque fastener assembly lubricant.

TECH TIP: Head studs should NOT be installed one at a time with the head on the car. You risk not only warping the cylinder head, but any oil or coolant that finds its way between the head gasket can ruin the tight seal that you are attempting to make. Pull the entire head and do it righ the first time!
