AMS Head Studs

The AMS/TMS Head Stud Package was designed to be the best kit ever made for your EVO. With AMS' experience building the world s quickest and highest horsepower Evolution VIII and Titan's experience building some of the fastest sport compact cars on the planet they both saw room for improvement in the head stud market.

Made from L19 alloy steel, these stock replacement studs are capable of achieving clamp loads of 230,000 260,000 psi. On top of the stud s added strength, AMS also increased the size of the washer to increase the clamping surface area on the head. The competition uses a .80 inch outer diameter washer while the AMS/TMS stud uses a .90 inch outer diameter washer, all while being able to maintain fitment in the head. From mild to wild rest assured by installing the best head studs on the market!

903/01/2011EVOAMS is a well known company to be leader in sport compact cars , however ARP l-19 head studs specs by AMS is a product that you cant go wrong with it . the l-19 head studs is a most for engines running more than 28psi of boost to prevent the head lifting which will cause the water to be blown away out of the over flow tank . in addition is that these studs was made in perfection in matter of quality , i strongly recommend it .
