The 2001-2008 8.1L engines require the installation of 271-99155-16 7/16" rocker arm studs (no machining required) and factory pushrod guideplates.

  • Made for popular V8 engines, Crane Cams Classic Aluminum Rocker Arms are the strongest, lightest, and most accurate aluminum rockers available. They have extruded aluminum bodies with needle bearing fulcrums and roller tips; the alloy maintains it strength at elevated temperatures. These rocker arms are the preferred choice of professional race engine builders, offering outstanding power advantages for street performance, moderate circle track, bracket drag racing, marine and off-road applications. Positive locking adjusting nuts included.

    Features
  • Heat-Treated CNC-Machined Billet Aluminum
  • Maximum Open Spring Pressure: 600 pounds
  • Precision Ground Steel Needle Bearings
  • Heat-Treated Steel Roller Tips
  • Adjustable Lock Nuts

    Note: Crane Classic Rocker Arms are intended for use in applications where open valve spring pressures do not exceed 600 pounds
