CP Pistons 9310 Steel Wrist Pin - 22mm x 2.500 in, .250 in Wall, Chamfered

A 9310 alloy steel wrist pin in CP-Carrillo's Type 3 straight wall design, gun drilled and honed in three stages, case hardened by a computerised gas process and then cryogenically treated to improve material strength and grain structure. Every pin is 100 percent Rockwell tested and held to a weight tolerance of plus or minus one gram. The ends are precision ground with an inner diameter radius and chamfered to accept wire locks, and the straight wall profile reduces pin bore galling. Sold by dimension rather than by application.
