What Is In This Collection

Valve springs, retainers and seals, big bore kits, lifters, pushrods and camshafts, from Feuling, S&S Cycles, Colony, Alloy Art, JIMS and Revolution Performance.

Sportster Fitment

Sportster covers '57-'22 - XL883, XL1200, Iron, Forty-Eight, Roadster and Nightster. The air-cooled XL is cable throttle. The liquid-cooled RH Sportster is a different motorcycle and does not share these parts - see RH Sportster.

Years that change what fits:

  • 2004 - the Sportster moved to a rubber-mounted frame, which changes a great deal of chassis hardware.
  • 2007 - fuel injection replaced the carburetor across the range.

Engine Parts Go By Cam Chest, Not By Model

This is the one that catches people out. Two bikes of the same year wearing the same badge can take completely different cams, plates, tensioners and oil pumps, because what matters is which engine generation is in the frame. Read the fitment list on the product page against your own motor rather than going by the model name.
