Part No: BTK-SU-XXX (various, per application)
Once the initial Bor-Tru Kit has been purchased, subsequent upgrades can be made to other engine families by purchasing a Bor-Tru "Step-Up" kit.
The Bor-Tru Step-Up kit consists of one engine application-specific deck plate and set-up spacer.
When using a deck mounted or portable boring bar or any type of boring equipment that must contact the deck surface of the block while boring, the Bor-Tru Deck Plate can be counterbored at the head bolt hole locations to ensure an absolutely flat surface. There is a nominal charge for this operation, specify part number BT-CB when ordering.
Note: A prerequisite to use of the Bor-Tru is a perfectly square deck surface, which can be achieved by use of the Blok-Tru.
