2 Deg Short (3/4in) Crank Key

The 2 Deg Short (3/4in) Crank Key from MR. GASKET is an essential ignition timing component designed for engine builders and performance mechanics who demand precision in small-block engine modifications. This specialized crank key solves a critical problem: controlling harmonic balancer timing during high-RPM operation or when running modified distributor indexing setups.

Whether you're fine-tuning ignition advance on a street performance engine or dialing in a race platform, this crank key allows you to adjust crankshaft timing relative to the camshaft without expensive machine work. The 2-degree offset design works with your harmonic balancer to shift ignition timing in precise, predictable increments, introducing a controlled rotational variance that effectively retards or advances your distributor's relationship to actual piston position.

Performance enthusiasts, engine rebuilders, and hot rod shops rely on crank keys like this when standard distributor adjustments are insufficient. The compact design and minimal engagement length make installation straightforward on most small-block platforms, ensuring that you can optimize combustion timing for your specific fuel octane and load conditions.
