Product Description

The ATI 918993 Crank Pin Drill Fixture Kit is a precision tool designed to secure the harmonic balancer on GM LS-based engines, including LS1, LS2, LS3, and LS6 variants produced between 1997 and 2006. This kit is particularly beneficial for high-performance applications such as supercharged, turbocharged, or racing engines where maintaining damper alignment is critical.

Constructed from billet aluminum with a black anodized finish, the drill fixture ensures durability and resistance to wear. The included hardened 11/64" drill bit allows for precise drilling, while the alignment tool guarantees accurate positioning during installation. Notably, the installation process does not require the removal of the timing cover or crankshaft, saving time and labor costs.

This kit is compatible with aftermarket dampers that feature a keyway slot, providing a secure fit and eliminating the potential for damper shift. By installing one or two dowel pins into the crankshaft, the kit ensures that the harmonic balancer remains firmly in place, even under high-rpm conditions. Whether you're building a street performance engine or preparing for track use, the ATI 918993 Crank Pin Drill Fixture Kit is an indispensable tool for achieving optimal engine performance and reliability.
