Tool Steel Wrist Pins, Locks & Teflon® Buttons

Wrist pins from tool steel are lighter and stronger than the stock wrist pins used by Harley®. We recommend using these in any performance application. Pin diameter recommendations for .791/.792” pins – use .085” wall pins in street engines with 3-1/2” to 3-5/8” bore; heavy-duty .140” wall in engines with 3-13/16”+ bore or smaller bore engines that see severe use. Teflon® buttons can be used instead of wrist pin spiral lock clips to eliminate any chance of the clips coming loose and causing damage. Buttons lengths are designed for use in Axtell pistons.

Wrist pin diameters have varied on H-D® engines over the years. .791” for Shovels & earlier EV XL’s, .792” for Ev Big Twins & late XL’s. Measure your stock ones if you’re unsure.
