🟦 New Part – Crankshaft Retention Essential (86–87 Turbo Buick)

Why You Want It
Because a loose balancer can destroy an engine fast. Old hardware stretches, fatigues, and loses clamping force over time. This new bolt and hardened washer restore proper retention at the crankshaft, helping prevent balancer walk, timing issues, and crank damage. If you’re reinstalling a balancer or finishing an engine build, replacing this hardware is cheap insurance that keeps everything locked in where it belongs.
