Here are the parts you need to replace those old rusted exhaust studs and nuts on your Harley Davidson engine.
This kit fits all Harleys with the 2- 8mm studs per pipe.
These studs have 8mm x 1.25 pitch threads on both ends. They have a unique ball lead to prevent cross threading. The 8mm x 1.25 12pt nuts have a 10mm 12-point wrench head.
ARP High Strength stainless bolts, studs, and nuts are virtually impervious to rust and corrosion. Rated at Grade 10.9/170,000 psi makes these stronger than regular grade 8 fasteners. These are maintenance free fasteners and come with a polished finish.
