Time-Sert 1812CORE M8 x 1.25mm Metric GM Rocker Arm Thread Repair Kit. Time Sert Metric GM Rocker Arm Thread Repair Kits Made in USA. Time Sert 1812CORE Thread Repair Inserts

The core drill included will allow a special 11.7mm length no flange insert to be installed deeper than the standard kit. The mechanic doing the repair will have to set the counterbore depth manually by hand.

If a repair has been made before and this is the second repair, you must purchase the 1812 Core BS (Big Sert) kit which is over-sized.
