- For stripped inboard threads: Use it when the inboard starter bolt hole’s threads are stripped or damaged (the hole itself must be intact)
- Precise alignment: Holds the rod that replaces the starter bolt on the hole’s original axis
- Prevents misalignment: Lines up the Trinity Starter Bracket before the starter is mounted
- Not always needed: Skip it if the inboard hole still has usable threads
- Fits LS and LT engines: Made to work with the Trinity Starter Bracket
- 100% made in the USA: From U.S.-made 1040 steel
- Patent pending: US2025/0382988A1
Note: The Trinity can’t repair a block where the whole starter ear, including the inboard bolt hole, is missing.
