ARP M96/M97 Carrier Through Bolt Kit Porsche Boxster, Cayman, 911 (was 106-23)

Porsche 986/987/996/997 Crankshaft Carrier Through Bolt Kit.

The factory carrier bolts are torque to yield (TTY) and must be replaced. This ARP kit features bolts that are stronger (and reusable) to help prevent shuffling and fretting of the main bearing saddles common to engines that see high performance driving or have been increased in displacement. Optional for street and required for the track.
