Counterweight - SBF 50oz Fits 74269 Supercharger

The Counterweight - SBF 50oz Fits 74269 Supercharger from PRO-RACE PERFORMANCE PRODUCTS is a precision harmonic balancer counterweight engineered for Small Block Ford engines running supercharger kits. When forced induction adds significant rotational mass and stress to your crankshaft, stock harmonic balancers become inadequate—this 50-ounce counterweight restores proper balance, reducing vibration and protecting critical engine internals from premature wear. Built for serious builders and enthusiasts who demand reliability alongside power.

Constructed from durable steel and finished with zinc oxide coating for corrosion resistance, this counterweight bolts directly onto compatible supercharger harmonic balancers—no machining or modifications required. The 50-ounce mass precisely counters the imbalance created by supercharger pulley systems and intercooler plumbing, maintaining harmonic stability across the entire RPM range. All necessary hardware is included, making installation straightforward for engine builders and experienced mechanics. The compact 3.4 x 2.85 x 6.05-inch design ensures clearance in tight engine bays while delivering measurable reduction in crankshaft deflection and parasitic vibration.

This counterweight is ideal for small block Ford enthusiasts building high-horsepower supercharged engines where longevity and balance are non-negotiable. Whether you're upgrading a 289, 302, 347, or other SBF variant with forced induction, proper harmonic balancing prevents bearing stress, reduces fatigue cracks, and extends engine life under sustained boost. Compatible with the 74269 supercharger harmonic balancer assembly, it performs best in combination with a quality damper ring and stock or aftermarket crank pulley. Weighing just 1.87 pounds, installation adds negligible mass while delivering substantial protection and reliability gains for supercharged street and strip applications.
