Counter Weight SBC Late

The Counter Weight SBC Late from Quarter Master is a precision-engineered flywheel counterweight designed for small-block Chevrolet engines running late-model configurations. As an experienced mechanic, you know that balancing a rotating assembly is fundamental to engine longevity and smooth operation. This OEM-style counterweight restores proper balance when you've modified your crankshaft or upgraded rotating components, preventing vibration, reducing strain on main bearings, and improving overall drivability. Built for the serious engine builder or performance enthusiast, this counterweight is essential when reconditioning or assembling SBC powerplants destined for high-RPM duty.

Quarter Master's Counter Weight SBC Late is machined from solid steel and finished in natural (bare) steel, delivering the durability required for extreme engine environments. The compact 1-piece seal design integrates seamlessly with Quarter Master flywheels and compatible crankshaft configurations, eliminating compatibility headaches during assembly. At just 0.95 lbs, this counterweight's mass is precisely calculated for late-model SBC specifications—every gram matters when balancing rotating assemblies to tight tolerances. The steel construction resists thermal cycling and maintains dimensional stability, critical when your engine is pushing boost or sustained high RPM.

Restoration shops, engine builders, and Chevy performance enthusiasts rely on this counterweight when rebuilding late-model small-block platforms—whether you're assembling a carbureted street engine or a fuel-injected performance package. Installation is straightforward for those familiar with crankshaft and flywheel assembly procedures; ensure proper balance verification before final installation to confirm optimal results. This is a genuine Quarter Master component, guaranteeing fitment with their complete flywheel systems and standard Chevy small-block applications requiring late-model counterweight geometry. Whether you're chasing reliable daily-driver power or building a weekend warrior, correct flywheel balance is non-negotiable.
