Custom Timing Cover Sizing Guide

Custom timing covers for Harley-Davidson motorcycles are sized according to which era of engine is installed in the bike. 

I support four different sizes:

  1. Milwaukee 8
  2. Twin Cam
  3. Shovelhead / Evolution / Late model Sportsters
  4. 2002 and earlier Sportsters

If you have any doubt about which one you need, give me a call. We’ll get it worked out.

Note for Milwaukee 8 riders: if your Milwaukee 8 has Variable Valve Timing (VVT), my current timing covers will not fit. I’m working on a version that will. Follow me on Facebook or Instagram for updates.
