  • 1" stainless steel sleeved bore
  • Unpolished aluminum
  • Height from center line to the top most point on the retaining bar is 3.5"
  • 3/8"-24 inverted flare ports on each side
  • 'Standard' or 'Long' thread 3/8"-24 IF male fittings should be used
  • 'Short' thread IF male fittings will not seal properly
  • Includes plugs for the side not used
  • Deep piston design for manual or power brakes 
  • Pushrod NOT included

Learn more about selecting the proper master cylinder for your vehicle by reading our tech article. Brake System Selection.

Notes
