FEULING PARTS

Feuling Parts Camshafts, Oil Pumps and Air Cleaners for Harley-Davidson

Feuling titles read like a parts list: a four-digit number, the line name (HP+, Race Series, OE+ or BA), then the engine family. We list about 535 Feuling products, nearly all under Motorcycle. Around 230 titles name the Twin Cam, 140 the Milwaukee-Eight (M8), 40 the Evolution, and a smaller group the Sportster, XR1200 and Buell.

The company's own history page describes Feuling as a designer of performance aftermarket parts for Harley-Davidson and says it designed and licensed cylinder head and valve technology to Harley-Davidson for the Twin Cam engine.

Camshafts and camchest kits

Camshafts holds about 100 listings, and roughly 75 of them are complete camshaft or camchest kits. The Reaper name appears in about 60 titles, with numbers such as 472, 543, 574, 594 and 630. Examples are the HP+ Reaper 472 chain drive kit for M8, the HP+ 574 chain drive camchest kit for Twin Cam and the Race Series Reaper 594 gear drive kit. M8 options include the 465 cam and the oil-cooled 508 Race Series camchest. Older engines have the 518 grind for the Evolution and the 580 series for Buell and XL. Titles say gear drive (about 30) or chain drive (about 70).

Oiling

About 25 listings sit in Oil Pumps & Parts, with more filed as oil system kits. The Hi Volume pump for Twin Cam and the HP+ pump for oil-cooled '17-'24 M8 show the split between engine families, and the HP+ pump with cam plate for water-cooled M8 covers the liquid-cooled head. Vented dipsticks come in black or polished for Dyna, Touring and Trike and M8 Softail.

Valvetrain and timing

Push Rods include HP+ stock-length rods for Twin Cam, 0.040" longer rods for M8 and adjustable Race Series rods for the Evolution Big Twin. Tappets & Lifters lists hydraulic roller sets like the standard OD set for M8 and Twin Cam, plus Race Series solid lifters. In Valve Guides, Springs & Parts, the Endurance beehive kit and high load beehive kit come with titanium retainers. For Twin Cam chain drives, Tensioners & Pulleys has the hydraulic conversion kit for '01-'06 and replacement tensioner pads.

Air cleaners and fuel

About 85 BA air cleaner kits are in Air Filters, sold by finish and filter color (red or black). The BA Series in black anodized with a red filter and the BA Race Series in raw are M8 listings. About 26 BA Slim kits cover Twin Cam and Evolution, such as the chrome Slim with a red filter. Fuel Injectors has 16 listings, including electric replacement injectors, and Oxygen Sensors has the 12 mm sensor for M8.

Shop tools and small parts

Around 27 fastener kits cover rocker boxes, cam plates and 12-point primary and transmission bolts. Eleven titles are tools, such as the crankshaft runout tool.

Matching the part

Check the engine family first: Twin Cam, M8, Evolution or Sportster. Then check the cooling type or year range, since oil-cooled and water-cooled M8 parts are listed separately. A few titles omit the years, so open the listing before ordering.

Feuling questions

What do HP+, Race Series and OE+ mean? They are line names in the titles. Compare the full title and description of each before choosing.

Do cam kits come with lifters and pushrods? Some Camchest kits name lifters or one-piece pushrods in the title. Others do not, so read the title.

Is gear drive or chain drive listed? Both, and the title says which.
