Feuling Engine

Feuling engine components are built around one pursuit — extracting every reliable horsepower from a Harley-Davidson V-twin without compromising longevity. Based in Oceanside, California, Feuling has earned its reputation through camchest kits, oil pumps, valvetrain hardware, and Race Series oil systems that deliver measurable gains on Twin Cam, Evolution, and Milwaukee-Eight powerplants. The Race Series oil systems, arguably Feuling's signature contribution, address one of the Twin Cam engine's known weaknesses — excess sump oil that robs horsepower and generates heat — by redesigning the scavenging system from first principles. The results show up on the dyno. Feuling's engineering credibility extends to the highest level of competition: their components have contributed to world land speed records, including a run at 332 mph that stands as the world's fastest motorcycle. For Milwaukee-Eight bagger builds, Twin Cam performance upgrades, or an Evolution rebuild where stock simply isn't enough, Feuling targets the systems that move the needle. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Feuling engine components for UK riders who want proven performance. Browse the full Feuling Engine range below.
