This listing features a solid, genuine factory cast iron front cylinder lifter block housing paired with a matched set of 4 premium Sifton hydraulic lifters. Having only seen around 8k miles of road use, these components have plenty of service life left and offer a substantial upgrade over standard stock configurations. []

🏍️ Fitment & Vehicle Compatibility:
Direct drop-in mechanical assembly for classic 74 cubic inch (1200cc) and 80 cubic inch (1340cc) Harley Shovelhead platforms running hydraulic valvetrains:
  • Harley-Davidson Shovelhead: Fits all electric and kick-start FL, FLH, FX, FXE, FXS, and FXWG models from 1966 to 1984. [1, 2]

🔍 Condition Notes:
This is a clean, low-mileage used vintage assembly set.
  • The Lifter Block: The OEM cast iron housing is structural, completely sound, and free from any cracks, chips, or hairline fractures along the mounting bolt tabs. Bores are smooth and free of ridge scoring.
  • The Sifton Lifters: All four hydraulic units feature excellent roller wheels that spin completely smooth and tight without flat spots or excessive lateral play. Please Note: One (1) of the Sifton assemblies is currently missing its internal adjustable pushrod screw socket piece. You will need to transfer over your existing adjuster screw to make the set complete.
Fast shipping with tracking included. Please review all photos to confirm your configuration before purchasing.
