What Is Here

Derby covers are here, joined by points and timer covers, cam covers, rocker box covers, pushrod tubes, horn covers, lifter blocks and the hardware to fit them. Brands include Performance Machine, Feuling, Arlen Ness, Joker Machine, Trask, Slyfox and Barnett.

Before You Order

Covers are cut for a specific motor family and, in the case of derby and primary covers, for 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. It is a cheap part to add to the order and an annoying one to be without with the cover already off.
