Our 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. Our Deep Cut 5-hole Derby and Timing Covers fit all 1999-Newer Twin Cam Bikes - all models of Dyna, Softail and Touring. For our "Contrast" series, we machine custom designs back into the aluminum after painting for a high contrast finish that makes them "pop". Other road names/slogans and designs available for purchase online at www.bigborecustom.com We accept Visa, MasterCard, PayPal, E-transfer and ship worldwide from our shop in Parksville BC via Canada Post. Makes the perfect gift.
