Description

PROFORM Aluminum Shaft-Mount Roller Rocker Arms, 1.7 Ratio, Chrysler Big Block (B/RB)

PN. 440-873

PROFORM shaft-mount aluminum roller rockers reduce valvetrain friction while the race-proven roller tip helps free up horsepower, extend valvetrain life and reduce wear on valve stem tips. Each rocker pivots on a bronze bushing, and oil travels up through the shaft and into the rocker beneath the bushing, where channels and holes lubricate the pivot. They are precision machined for consistency and ratio accuracy, and adjustable pushrod tips allow precise lash setting.

Part number 440-873 is a set of 16 1.7 ratio rockers for Chrysler Big Block (B/RB) engines.

Features and Benefits:

  • Aluminum shaft-mount roller rockers
  • Roller tip reduces wear on valve stem tips
  • Bronze bushings
  • Shaft-fed oiling to the pivot
  • Adjustable pushrod tips
  • Precision machined for ratio accuracy
  • 16 rockers, hardened shafts and spacer hardware included
