FAQ
Frequently Asked Questions
Generally, no. Most rod bolts are torque-to-yield (TTY) or stretch bolts designed for one-time use. Reusing them can lead to under-torquing and failure.
No. A rod bolt secures the connecting rod, while a head bolt secures the cylinder head to the engine block. They are different parts with different specifications.
They endure extreme cyclical stresses from combustion forces. Failure allows the connecting rod to detach, often destroying the engine completely.
