What is the primary function of a wrist pin bushing?

A wrist pin bushing sits between the connecting rod and the piston's wrist pin. Its main job is to provide a smooth, low-friction surface for the wrist pin to rotate within the connecting rod, while also maintaining the correct oil clearance.

What material are these Manley bushings made from?

These Manley wrist pin bushings are made from a strong bronze alloy. Bronze is chosen for its good wear resistance and its ability to handle the high loads and rotational forces in this part of the engine.

Do these bushings come ready to install, or do they need further machining?

These bushings typically require honing to the correct size after installation. This step is crucial for achieving the precise oil clearance needed for your specific engine build, ensuring proper lubrication and reducing wear.

About this part

Product Details

Manley's wrist pin bushings are made from a strong bronze alloy, specifically chosen for its durability and ability to handle the high loads found in performance engine applications. These bushings are designed to fit SBC (Small Block Chevy) connecting rods with a .927-inch wrist pin diameter, ensuring a precise fit for proper oil clearance and reduced friction. When you're rebuilding an engine, getting the connecting rod and piston pin connection right is crucial for longevity and performance. These bushings help maintain that critical clearance, preventing premature wear and potential damage.

The bronze material offers good wear resistance and self-lubricating properties, which are important in this high-stress area of the engine. Proper installation of these bushings is key; they need to be honed to the correct size after installation to achieve the exact oil clearance specified by your engine build plan. This attention to detail ensures that your engine runs smoothly and reliably under demanding conditions.
