Stealth Pipes’ Derby Covers are CNC machined in the USA from aircraft-grade 6061 aluminum and built to deliver durability, clean style, and rider personalization. Available for both M8 Touring models (2015+) and Twin Cam Harleys (1999–2017 Dyna, 2007–2019 Softail, 2007–2015 Touring), these covers come in a raw machined finish and can be engraved with the design of your choice.

Designed for precise fitment with OEM specs, each Derby Cover uses stock style flat gaskets (not included) and stock hardware (Twin Cam) or requires flat style gaskets (M8). They’re the perfect blend of American made quality and custom ready design, built for riders who want to make their Harley stand out.
