Special Features

  • Exact 3/16″ × 3/4″ Dimensions – Precision-cut to precisely fit common aftermarket LS crank balancer hubs and classic Small‑Block Chevy keyways without modification.
  • Steel-Alloy Construction – Engineered to handle high RPM torque loads and dampen vibration without deforming or collapsing under pressure.
  • Aftermarket LS & SBC Compatibility – Perfectly suited for billet or aftermarket LS crankshafts and older Chevy small-block applications—ideal for balancer, pulley, or gear seating.
  • Not for OEM LS Use – Explicitly not compatible with OEM LS cranks; GM PN 12561513 is the recommended stock replacement for factory LS timing gear.
  • DIY Essential for Engine Builds – A small part with big impact: ensure accurate crankshaft accessory positioning during engine rebuilds, balancer swaps, or performance builds.

Description

Secure your crankshaft accessories with this precision-engineered Woodruff key from Michigan Motorsports. Measuring 3/16″ in width and 3/4″ in length, it's designed specifically for the second key slot on aftermarket LS crankshafts (balancer hub keyway) and classic Small Block Chevy engines. Crafted from high-strength steel alloy to resist shear and slipping, this key delivers reliable timing alignment and accessory engagement when stock keystocks fail. Note: This is not compatible with OEM LS crank provisions (use GM PN 12561513 for OEM use).
