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.
TIP: When ordering, check the pin length of your pistons as some manufacturers use different lengths.
