This "AIRBORNE THUMPERHEADS" cover is low profile, at under 1/2" thick, and just over 7 3/4" in diameter. Includes o-ring groove for OEM change-over. Fit for Milwaukee Eight engines.
Derby covers are CNC machined from high strength, 6061-T6 aircraft grade billet aluminum. Finished with a durable powder coat finish that will add class and style to your Harley Davidson motorcycle.
For our “Contrast” series, we machine custom designs back into the aluminum after painting for a high contrast finish that makes them “pop”.
