What does 'taper wall' mean for this piston pin?

A taper wall design means the thickness of the pin's wall varies, often being thicker in the center and thinner towards the ends. This can help manage stress and reduce weight compared to a uniformly thick wall.

Why would I choose a non-chromed piston pin?

Some engine builders prefer non-chromed pins for specific material compatibility or to avoid potential issues with plating in certain high-performance applications. It's often a choice based on the overall engine build strategy.

What does 'superfinished outer diameter' mean?

Superfinishing is an advanced surface finishing process that creates an extremely smooth surface. This helps reduce friction between the pin and the piston or connecting rod, contributing to better performance and durability.
