Weistec ARP 625+ Head Studs

Weistec has teamed up with ARP, the leading name in performance engine hardware, to bring you an exceptional upgrade for your engine. Say goodbye to factory head bolts and hello to a more reliable connection with our head studs!

Why Choose Head Studs?

Head studs play a crucial role in securing the cylinder heads to the engine block. This connection is vital, as it allows coolant and oil to flow seamlessly between the two components. The head gasket works hard to keep everything separate—coolant, oil, and air charge—thanks to the pressure generated by the head bolts. However, factory head bolts are designed to be "torque to yield," which means they stretch permanently when installed. This can lead to issues, especially with the stock M156 engines, where oil leaks can occur due to a less-than-perfect connection.

Strength You Can Trust

With an impressive tensile strength of over 260,000 PSI, the Weistec ARP 625+ head studs provide a much stronger hold than the factory bolts, without the risk of permanent stretching. This means you can count on your engine to perform reliably without worrying about leaks between the heads and the block. Quality head studs are essential for any engine aiming for high power levels!

Features

  • 260,000 PSI tensile strength
  • 255,000 PSI yield strength
  • Complete replacement for factory head bolts
  • Enhanced head-to-block connection to eliminate leaks
  • Reusable design, unlike the factory bolts which are single-use

Fitment

  • Mercedes-Benz W219 CLS63 AMG (2007-2010)

Upgrade your engine's reliability with the Weistec ARP 625+ head studs and enjoy peace of mind on your performance journey!

What Is Weistec Engineering?

Based out of Orange County, California, Weistec Engineering is an industry leader in research, development, and design.

Michael Weiss and Steve Atneyel decided to branch out on their own and combine their expertise and experience.
