The gearset of your automatic transmission is surrounded by a protective case made of iron or aluminum. Corrosion or damage may require a replacement for your stock case, and if you’re making upgrades for competition, you may need a beefed-up case for safety.
Stabilizing your high-performance engine is an important job, so you should go with a name brand you trust, instead of some third-party reseller. Summit Racing Equipment sells rocker arm stud girdles from manufacturers like COMP Cams, Harland Sharp, Trick Flow Specialties, Lunati, Howards Cams, and more.
