Frequently Asked Questions
Why do LS engines need to be pinned?
Factory LS crankshafts rely on friction to hold the balancer in place, which can fail under high load or forced induction. Pinning the crank provides a secure mechanical lock that prevents slippage and timing issues.
Do I need to remove the crankshaft to use this kit?
No. The ATI918993 kit allows in-vehicle installation. The included drill fixture ensures precise hole alignment while the crank remains in the engine.
Is this kit required for installing an ATI Super Damper?
Yes. ATI recommends pinning the crankshaft whenever a Super Damper or other high-performance balancer is installed on LS engines.
Can I reuse the hardened pins?
No. The pins are designed for one-time installation to ensure the tightest fit and reliability. Always use new pins when reinstalling or replacing the damper.
