Suzuki G13/G16 Stainless Stud Kits
These are designed to work with the G13/16 8 Valve only! If you have measurements for another Suzuki engine, we would be glad to size up other studs for you. Studs, Nuts and Washers.
We have a variety of stainless hardware, some to fit your engine directly, other stuff is generic bolts or nuts that you may find useful, as metric stainless hardware is often tough to find. Please keep in mind that stainless-on-stainless threads tend to "gall" and will likely leave you with a handful of threads and red in the face. This is why our stud kits come with stainless studs, but not stainless nuts. Other hardware we offer is either black oxide coated or zinc coated for rust prevention. You can make a specific request for hardware if you know the specifications (diameter, thread pitch, length, etc.) and we will do our best to find it for you. Even though we offer hardware kits, you can always call and request something specific, or buy pieces individually, if available. We can also CNC or EDM specific hardware for a custom application. This is usually not cost-effective, and most pieces of hardware can be found off the shelf. Contact us for more details, or to order some hardware.
