SBM Wrist Pin Bushing .984in

The SCAT Enterprises SBM Wrist Pin Bushing .984in (part number B984) is a precision bronze bushing engineered for Small Block Mopar engine builders and rebuilders. This wrist pin bushing serves as the critical bearing surface between the connecting rod and wrist pin, enabling smooth piston articulation under high combustion pressures while maintaining the tight tolerances required for reliable engine operation.

The bushing features a 0.959-inch inner diameter and 1.043-inch outer diameter, with a 1.254-inch length. Bronze material provides superior bearing characteristics and wear resistance compared to softer alloys, critical for absorbing the cyclical loads generated during combustion and reciprocation. These specifications ensure proper fit within Small Block Mopar connecting rods while maintaining the clearances necessary for adequate oil film formation. Each bushing is supplied in natural (unplated) bronze finish, ready for machine work during engine assembly or rebuild operations.

This bushing is designed for serious engine rebuilders, hot rodders, and racing enthusiasts working on Small Block Mopar platforms. It addresses the precision bearing requirements of high-performance builds where original components may be worn or where stronger bushing material is preferred for durability. The .984-inch designation indicates the outer diameter specification, distinguishing this from other Small Block Mopar bushing sizes and ensuring compatibility with properly sized connecting rod bores.

SCAT Enterprises is recognized within the engine rebuilding community for precision crankshaft and connecting rod components. Proper wrist pin bushing selection and installation is fundamental to building Small Block Mopar engines that deliver consistent performance and longevity across street, off-road, and competition applications.
