Dyna Engine & Primary Covers

Engine & Primary Covers for the Harley-Davidson Dyna, '91-'17. The visible outside of the motor, and the cheapest way to change how a bike looks without touching a moving part.

What Is In This Collection

Derby covers, hardware, points covers, cam covers and rocker box covers, from Feuling, Arlen Ness, Performance Machine, Joker Machine, Trask and Barnett.

Dyna Fitment

Dyna covers '91-'17 - FXD Super Glide, Street Bob, Fat Bob, Wide Glide, Low Rider and Switchback. The Dyna is cable throttle throughout its run, so throttle-by-wire parts do not apply.

Years that change what fits:

2006 - the Dyna took the revised cam chest a year before the rest of the range.
2017 - the Dyna line ended and was replaced by the M8 Softail.

Before You Order

Covers are cut for a specific motor family and, for derby and primary covers, a specific primary cover shape - Evo, Twin Cam and Milwaukee-Eight are all different, and a five-hole and a three-hole derby cover are not interchangeable. Most covers need a new gasket or O-ring on refitting, which is a cheap part to add to the order and an annoying one to be without with the cover already off.

Engine parts for this platform are also split by motor generation: Evo Motor, Twin Cam '99-'05 and Twin Cam '06-'17.
