ARP Toyota 2JZ GE GTE Head Studs – Undercut

Description

ARP Toyota 2JZ GE GTE Head Studs – Undercut

Undercut ARP2000 Head Bolts for Toyota 2JZ 

U/C is an abbreviation for “Undercut”, which means that the bolts have a slightly smaller diameter on the unthreaded part of the bolt.

The undercut improves the tightening of the cylinder head more evenly compared to those that are not undercut as they stretch. This can be an advantage if, for example, the cylinder head gasket would not be 100% smooth over the entire surface, then the bolts compensate for this.
