Evo X (4B11T) Wrist Pins

Evo X (4B11T) Wrist Pins
These are optional heavy duty wrist pins listed by diameter, length and wall thickness.  Chamfered pins fit pistons with wire locks; straight pins use spiral locks.  Increased wall thickness helps prevent pin flex, piston deck cracking, pin hole elongation in the rod and piston and simple breakage.  Pro pins feature upgraded steel alloy for greater strength and gall resistance.

New super alloy pins exceed 325,000 psi tensile strength and feature anti-friction/anti-gall coatings.  These are perfect for extreme boost applications.
