James Gaskets Derby Cover Gaskets

4 products — part of all Derby Cover Gaskets

James Gaskets derby cover gaskets reflect 45 years of exclusive Harley-Davidson sealing expertise — the brand has made nothing but HD gaskets, seals, and O-rings since 1979, which means the compound choice for a primary derby cover gasket is based on actual knowledge of Harley-Davidson primary chemistry, thermal cycling, and surface finish, not a general-purpose solution. Dyna models from 2006 to 2017, Softail from 2007 to 2018 (excluding the 2018 FLSB Sport Glide), and FLT/Touring from 2007 to 2025 including Trikes are covered, with additional listings for vintage Big Twin applications back to 1970 and 1999 to 2006 Softail six-speed primary units. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, carries the James Gaskets range through Iron Stable. When you're replacing a primary derby cover gasket on a Harley-Davidson, the material matters as much as the fitment — 45 years of single-brand focus on HD applications is why James Gaskets is the professional shop standard.
