What material are these wrist pins made from?

These wrist pins are constructed from 9310 steel. This material is chosen for its strength and ability to withstand high stress in performance engine applications.

What does the .210 wall thickness signify?

The .210 inch wall thickness refers to the thickness of the tube that makes up the wrist pin. A thicker wall generally indicates increased strength and resistance to bending or deformation under load.

Are these wrist pins compatible with all pistons?

These are 21mm wrist pins. You will need to ensure that your pistons are designed to accept a 21mm wrist pin diameter for proper fitment and function.
