THEY ARE NOW INSTOCK!

We are proud to introduce our line of head studs and main studs for the SR. We have to come to realize that the engagement on the ARP off the shelf ones dont thread into the block completely and not bottoming out so it does not giving enough grab. So with these we developed will be the correct length and actually stronger and better material.

ARP current head stud/main stud
8740 CHROME MOLY: Until the development of today’s modern alloys, chrome moly was popularly considered a high strength material. Now viewed as only moderate strength, 8740 chrome moly is seen as a good tough steel, with adequate fatigue properties for most racing applications, but only if the threads are rolled after heat-treatment, as is the standard ARP production practice. Typically, chrome moly is classified as a quench and temper steel, that can be heat-treated to deliver tensile strengths between 180,000 and 210,000 psi.

Mazworx Headstud/Main stud material

ARP2000®: An exclusive, hybrid-alloy developed to deliver superior strength and better fatigue properties. While 8740 and ARP2000 share similar characteristics – ARP2000 is capable of achieving clamp loads in the 215,000-220,000 psi range. ARP2000 is used widely in short track and drag racing as an up-grade from 8740 chrome moly in both steel and aluminum rods. Stress corrosion and hydrogen embrittlement are typically not a problem, providing care is taken during installation.

Made from ARP2000 material
12 point
220ksi tensile strength
Straight shank/bullet ends from complete bottom out
Comes with (10) studs, (10) washers, (10) nuts (1) assembly lubricant and instructions.

The Mazworx Main Studs WILL CLEAR without upper oil pan machining!!!!!!!

How does this compare to your 1/2" head stud upgrade ?

Mazworx_Sales · 05-04-2009, 08:28 AM

This is an oem upgrade.

s15specR · 05-04-2009, 08:54 PM

So its still not as good as your 1/2" upgrade ? How does it compare to the L19 material available for the 2jz etc ?

Mazworx_Sales · 05-05-2009, 08:53 AM

These are for OEM setup. These have more thread engagement than the off the shelf ARP. Its hard to compare a 1/2" stud kit to this or a 400.00 L19 head stud kit. They are do different jobs.
