The Wrist Pin Bushing – BBC Pontiac by EAGLE (EAGB991-1) is an essential internal engine component designed specifically for big-block Pontiac engines. This bushing is crucial for ensuring precise piston-to-rod articulation during engine operation, making it ideal for those rebuilding or refreshing classic Pontiac big-blocks or high-performance stroker assemblies.
Engineered to provide controlled clearance, this bushing helps prevent catastrophic piston seizure and rod knock during sustained RPM operation. Manufactured to OEM-equivalent tolerances, it ensures a precise sliding fit between the wrist pin and connecting rod eye, accommodating the lateral and angular loads generated during combustion while dissipating heat and reducing friction.
Mechanics and engine builders trust EAGLE components for their reliability in BBC Pontiac restorations and performance upgrades. Proper installation requires honing or reaming of the connecting rod bore to achieve the recommended clearance, with most builders specifying a 0.0005"–0.0015" press fit deviation for optimal performance.
