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.
