ATI Performance Products Pin Drill Fixture Kit

The ATI Performance Products Pin Drill Fixture Kit line, also called crank pin drill fixture kits or crankshaft pinning kits, lets you drill the crankshaft snout accurately and install hardened dowel pins. The pins act like keys. They stop a harmonic damper or crank hub from spinning or twisting on the crankshaft.

Key Features:

• Made to pin the crankshaft on high-RPM, supercharged, turbocharged and high-horsepower nitrous engines
• Precision drill fixture locates on the crank snout to guide the drill accurately
• Hardened drill bit and pins for the crankshaft
• Lets you install one or two dowel pins in the crank
• Helps keep an aftermarket damper or hub from shifting on the snout, which is useful where the crankshaft has no keyway
• Instruction sheets are available for each kit

ATI Performance Products builds high-performance drivetrain and damper components for street, strip and racing use. Each kit in this line gives engine builders and racers a controlled way to add pin retention to the crankshaft.
