TOOL STEEL WRIST PINS

Racers world wide know that you can not buy a stronger wrist pin than APE tool steel pins. APE manufacturers these premium pins in their own shop. Starting with prime aircraft grade tool steel, the pins are CNC machined, heat treated to precise rockwell numbers and ground to size.

Note that none of the piston manufacturers include true tool steel pins as standard with their piston kits. (The exception is the new JEs for the 2000+ GSXR 750)

No matter who's pistons you are using, why risk catastrophic engine failure. Get APE tool steel pins.

Every quarter mile run ever made in the five second zone and over 235 mph have had APE pins holding it together.
Those same pins are only a phone call away.
