Audi 5-cylinder main stud kit. Main studs help eliminate main cap walk and fretting while protecting the threads in the block. They also give more accurate torque readings and proper cap alignment every time.

Made from heat-treated 8740 chrome moly with a black oxide finish, it is far stronger than factory and Grade 8 hardware.
