LS Crankshaft Pin Drill Fixture Kit #918993 ATI

*** IN STOCK SHIPS TODAY *** When building a high horsepower LS engine the one downfall is the crankshaft has no keyway provisions from the factory. When installing a crank hub or aftermarket dampner this is the time you want to purchase this kit and drill the crank for double heat-treated steel dowel pins to act as woodruff keys in the crankshaft to help keep the hub from spinning.

ATI Performance Products crankshaft pin drill fixture kits are designed to pin the crankshaft for high-rpm, supercharged, turbocharged or high-horsepower nitrous oxide engines. They include a billet steel black-anodized drill fixture, a hardened 11/64" drill bit, an alignment tool and pins for the crankshaft.

Crank pin drill fixture fits LS1, LS2, LS3, LS6 and LS7 crankshafts that are 1.438". Includes detailed installation instructions.
