Frequently Asked Questions

Why would I need new dowels?

Original dowels often become galled, scored, or distorted during removal. New dowels ensure clean, accurate cylinder seating during a top-end rebuild.

How many dowels do I need?

This 4-pack covers one complete top-end job on an EVO Big Twin or Sportster.

Will these fit my Twin Cam engine?

No — these dowels are for EVO engines only (1984-1999 Big Twin and 1986-2014 Sportster). Twin Cam engines use different dowel specifications.

Do I need any special tools to install?

No — dowels are hand-placed into the crankcase bore during cylinder installation. A light coat of assembly lube helps with alignment.
