Description

Introducing our high strength chromloy head stud washer set for 4G63!

The shank prevents the stud washer from moving around and eating into the head as well as prevents the boss from caving in under high loads. The washer is also slightly larger than standard for better load distribution.

We also offer a machining service to machine (the normally eroded) surface of the head stud boss and clearancing for the washer shank which is required for installation.

If you have a high performance 4G63 in the build, this is a must!
